Racial achievement gap in the United States

From Wikipedia, the free encyclopedia
The racial achievement gap in the United States refers to the educational disparities between various ethnic groups. It manifests itself in a variety of ways: among students, blacks and Hispanics are more likely to receive lower grades, score lower on standardized tests, drop out of high school, and they are less likely to enter and complete college than whites, who similarly score lower than East Asians who originate from the rich industrialized developed countries of Taiwan, Japan, Singapore, South Korea and China.

Evidence of the racial achievement gap

Over the past 45 years, students in the United States have made notable gains in academic achievement. However, the racial achievement gap remains because not all groups of students are advancing at the same rates. Evidence of the racial achievement gap has been manifested through standardized test scores, high school dropout rates, high school completion rates, college acceptance and retention rates, as well as through longitudinal trends. While efforts to close the racial achievement gap have increased over the years with varying success, studies have shown that disparities still exist between achievement levels of minorities compared to their White counterparts.

Early schooling years

Kindergarten through fifth grade

The racial achievement gap has been found to exist before students enter kindergarten for their first year of schooling. At the start of kindergarten, Hispanic and black students have math and reading scores substantially lower than those of white students. While both Hispanics and blacks scores have significantly lower test scores than their white counterparts, Hispanic and black have scores that are roughly equal to each other. In a study published in 2009, Reardon and Galindo (2009) specifically examine test scores by race and ethnicity. The data Reardon and Galindo (2009) use comes from the ECLS-K, sponsored by the National Center for Education Statistics. The ECLS-K contains data on a nationally representative sample of approximately 21,400 students from the kindergarten class of 1998–1999. Students in the sample were assessed in reading and mathematics skills six times from 1998 to 2004. The content areas of the tests are based on the National Assessment of Educational Progress (NAEP) fourth-grade content areas, adapted to be age appropriate at each grade level. The assessments were scored using a three-parameter Item Response Theory (IRT) model. Reardon and Galindo (2009) found that average Hispanic and black students begin kindergarten with math scores three quarters of a standard deviation lower than those of white students and with reading scores a half standard deviation lower than those of white students. Six years later, Hispanic-white gaps narrow by roughly a third, whereas black-white gaps widen by about a third. More specifically, the Hispanic-white gap is a half standard deviation in math, and three-eighths in reading at the end of fifth grade. The trends in the Hispanic-white gaps are especially interesting because of the rapid narrowing that occurs between kindergarten and first grade. Specifically, the estimated math gap declines from 0.77 to 0.56 standard deviations, and the estimated reading gap from 0.52 to 0.29 in the roughly 18 months between the fall of kindergarten and the spring of first grade. In the four years from the spring of first grade through the spring of fifth grade, the Hispanic-white gaps narrow slightly to 0.50 standard deviations in math and widening slightly to 0.38 deviations in reading.

Third through eighth grade

In a 2009 study Clotfelter et al. examine test scores of elementary and middle school students by race. The data used in the study comes from administrative records created by North Carolina's Department of Public Instruction and maintained by the North Carolina Education Research Data Center and are not nationally representative. North Carolina requires all students to take standardized achievement tests in both math and reading at the end of every grade between grades 3 and 8. In order to make comparisons across years, Clotfelter et al. (2009) normalized the scaled scores for each test in every year over all students in the state who took the test so that each test would have a mean score of 0 and a standard deviation of 1. On this normalized scale, positive scores denote above-average performances relative to the statewide average, and negative scores denote below-average performance. Analysis by Clotfelter et al. (2009) found gaps between four different racial groups: whites, Asians, Hispanics, and blacks. Essentially, while the black-white gaps are substantial, both Hispanic and Asian students tend to gain on whites as they progress in school. The white-black achievement gap in math scores is about half a standard deviation, and the white-black achievement gap in reading is a little less than half a standard deviation. By fifth grade, Hispanic and white students have roughly the same math and reading scores. By eighth grade, scores for Hispanic students in North Carolina surpassed those of observationally equivalent whites by roughly a tenth of a standard deviation. Asian students surpass whites on math and reading tests in all years except third and fourth grade reading.

Secondary school

In a 2006 study, LoGerfo, Nichols, and Reardon (2006) found that, starting in the eighth grade, white students have an initial advantage in reading achievement over black and Hispanic students but not Asian students. Using nationally representative data from by the National Center for Education Statistics (NCES)—the Early Childhood Longitudinal Study (ECLS-K) and the National Education Longitudinal Study (NELS:88), LoGerfo, Nichols, and Reardon (2006) claim that black students score 5.49 points lower than white students and Hispanic students score 4.83 points lower than white students on reading tests. These differences in initial status are compounded by differences in reading gains made during high school. Specifically, between ninth and tenth grades, white students gain slightly more than black students and Hispanic students, but white students gain less than Asian students. Between tenth and twelfth grades, white students gain at a slightly faster rate than black students, but white students gain at a slower rate than Hispanic students and Asian students.

In eighth grade, white students also have an initial advantage over black and Hispanic students in math tests. However, Asian students have an initial 2.71 point advantage over white students and keep pace with white students throughout high school. Between eighth and tenth grade, black students and Hispanic students make slower gains in math than white students, and black students fall farthest behind. Asian students gain 2.71 points more than white students between eight and tenth grade. Some of these differences in gains persist later in high school. For example, between tenth and twelfth grades, white students gain more than black students, and Asian students gain more than white students. There are no significant differences in math gains between white students and Hispanic students. By the end of high school, gaps between groups increase slightly. Specifically, the initial 9-point advantage of white students over black students increases by about a point, and the initial advantage of Asian students over white students also increases by about a point. Essentially, by the end of high school, Asian students are beginning to learn intermediate-level math concepts, whereas black and Hispanic students are far behind, learning fractions and decimals, which are math concepts that the white and Asian students learned in the eighth grade. Black and Hispanic students end twelfth grade with scores 11 and 7 points behind those of white students, while the male-female difference in math scores is only around 2 points.

Standardized test scores

The racial group differences across admissions tests, such as the SAT, ACT, GRE, GMAT, MCAT, LSAT, Advanced Placement Program examinations and other measures of educational achievement, have been fairly consistent. Since the 1960s, the population of students taking these assessments has become increasingly diverse. Consequently, the examination of ethnic score differences have been more rigorous. Specifically, the largest gaps exist between white and African American students. On average, they score about .82 to 1.18 standard deviations lower than white students in composite test scores. Following closely behind is the gap between white and Hispanic students. Asian American students overall performance were higher than those of White students except Asian American students performed one quarter standard deviation unit lower on the SAT verbal section, and about one half a standard deviation unit higher in the GRE Quantitative test. However, in the new current version of the SAT, Asian-American students of Taiwanese, Korean, Japanese, Indian and Han Chinese descent have scored higher on both the verbal and math sections of the new SAT test than whites and all other student racial groups.

The National Assessment of Educational Progress reports the national Black-White gap and the Hispanic-White Gap in math and reading assessments, measured at the 4th and 8th grade level. The trends show both gaps widen in mathematics as students grow older, but tend to stay the same in reading. Furthermore, the NAEP measures the widening and narrowing of achievement gaps on a state level. From 2007 to 2009, the achievement gaps for the majority of states stayed the same, although more fluctuations were seen at the 8th grade level than the 4th grade level.

The Black-White Gap demonstrates:
  • In mathematics, a 26-point difference at the 4th grade level and a 31-point difference at the 8th grade level.
  • In reading, a 27-point difference at the 4th grade level and a 26-point difference at the 8th grade level.
The Hispanic White Gap demonstrates:
  • In mathematics, a 21-point difference at the 4th grade level and a 26-point difference at the 8th grade level.
  • In reading, there is a 25-point difference at the 4th grade level and a 24-point difference at the 8th grade level (NAEP, 2011).
The National Educational Longitudinal Survey (NELS, 1988) demonstrates similar findings in their evaluation of assessments administered to 12th graders in reading and math.

High school dropout rates

According to the US Department of Education, event dropout rate is the percentage of high school students who dropped out of high school between the beginning of one school year and the beginning of the next school year. Five out of every 100 students enrolled in high school in October 2000 left school before October 2001 without successfully completing a high school program. The percentage of students who were event dropouts decreased from 1972 through 1987. However, despite some year-to-year fluctuations, the percentage of students dropping out of school each year has stayed relatively the same since 1987. Data from the October 2001 Current Population Survey (CPS) show that black and Hispanic students were more likely to have dropped out of high school between October 2000 and October 2001 than were white or Asians/Pacific Islander students. During this period, 6.3% of black and 8.8% of Hispanic high school students dropped out compared to 4.1% of white and 2.3% of Asian/Pacific Islander high school students.

Asian/Pacific Islander 2.3%
White 4.1%
Black 6.3%
Hispanic 8.8%

According to the US Department of Education, status dropout rates measure the percentage of individuals who are not enrolled in high school and who lack a high school credential, independent of when they dropped out. Status rates are higher than event rates because they include all dropouts in this age range, regardless of when they last attended school or whether or not they ever entered the US education system. In October 2001, about 3.8 million 16- through 24-year-olds were not enrolled in a high school program and had not completed high school. These individuals accounted for 10.7% of the 35.2 million 16- through 24-year-olds in the United States in 2001. In 1972, the white status dropout rate was 40% and the black status dropout rate was 49%. Because the black rate declined more steeply than the white rate, there has been a narrowing of the gap between the dropout rates for blacks and whites. However, this narrowing occurred in the 1980s, and the gap between whites and blacks has remained fairly constant since 1990. The percentage of Hispanics who were status dropouts has remained higher than that of blacks and whites in every year since 1970. Even though Hispanics represented approximately the same percentage of the young adult population as did blacks, Hispanics were disproportionately represented among status dropouts in 2001. Also in 2001, the status dropout rate for Asians/Pacific Islanders ages 16–24 was lower than for any other 16- through 24-year-olds. Specifically, the status rate for Asians/Pacific Islanders was 3.6%, compared with 27.0% for Hispanics, 20.9% for blacks, and 7.3% for whites.

High school completion rates

Status completion rates measure the percentage of a given population that has a high school credential, regardless of when the credential was earned. In 2001, 86.5% of 18- through 24-year-olds not enrolled in elementary or secondary school had completed high school. Status completion rates increased from 82.8% in 1972 to 85.6% in 1990. Since 1991, the rate has shown no consistent trend and has fluctuated between 84.8% and 86.5%. High school status completion rates for white and black young adults increased between the early 1970s and 1990 but has remained relatively the same since 1990. Specifically, status completion rates for white students increased from 86.0% in 1972 to 89.6% in 1990. Since 1990, white completion rates have remained in the range of 89.4–91.8%. In 2001, 91.0% of white and 85.6% of black 18- through 24-year-olds had completed high school. The percentage of black students completing high school rose from 72.1% in 1972 to 85.6% in 2001. The gap between black and white completion rates narrowed between 1972 and 2001. In 2001, 65.7% of all Hispanic 18- through 24-year- olds completed high school. This percentage compares to 91.0% of whites, 85.6% of blacks, and 96.1% of Asians/Pacific Islanders. Essentially, in 2001, whites and Asians/Pacific Islanders were more likely than their black and Hispanic peers to have completed high school. Also, whites completed high school at a higher rate than both blacks and Hispanic students. Black students completed high school at a higher rate than Hispanics.

2001 Status Completion Rates: 18- to 24-year-olds by Race

Asian/Pacific Islander 96.1%
White 91.0%
Black 85.6%
Hispanic 65.7%

The four-year completion rate is the percentage of 9th-grade students who left school over a subsequent 4-year period while also completing a high school credential. Data for the 4-year completion rate calculations are taken from the Common Core of Data (CCD). The 4-year completion rate calculation is dependent on the availability of dropout estimates over a 4-year span, and current counts of completers. Because dropout rate information was missing for many states during the 4-year period considered by the US Department of Education, 4- year completion rate estimates for the 2000-01 school year are only available for 39 states. Since data were not available from all states, an overall national rate could not be calculated. However, among reporting states, the high school 4-year completion rates for public school students ranged from a high of 90.1% in North Dakota to a low of 65.0% in Louisiana.

SAT scores

Racial and ethnic variations in SAT scores follow a similar pattern to other racial achievement gaps. In 1990, the average SAT was 528 for Asian-Americans, 491 for whites, , 429 for Mexican Americans and 385 for blacks. 34% of Asians compared with 20% of whites, 3% of blacks, 7% of Mexican Americans, and 9% of Native Americans scored above a 600 on the SAT math section. On the SAT verbal section in 1990, whites scored an average of 442, compared with 410 for Asians, 352 for blacks, 380 for Mexican Americans, and 388 for Native Americans. In 2015, the average SAT scores on the math section were 598 for Asian-Americans, 534 for whites, 457 for Hispanic Latinos and 428 for blacks. Additionally, 10% of Asian-Americans, 8% of whites, 3% of Mexican Americans, 3% of Native Americans and 2% of blacks scored above 600 on the SAT verbal section in 1990. Race gaps on the SATs are especially pronounced at the tails of the distribution. In a perfectly equal distribution, the racial breakdown of scores at every point in the distribution should ideally mirror the demographic composition of test-takers as whole i.e. 51% whites, 21% Hispanic Latinos, 14% blacks, and 14% Asian-Americans. But ironically, among the highest top scorers, those scoring between a 750 and 800 (perfect scores) over 60% are East Asians of Taiwanese, Japanese, Korean and Han Chinese descent, while only 33% are white, compared to 5% Hispanic Latinos and 2% blacks.

There are some limitations to the data which may mean that, if anything, the race gap is being understated. The ceiling on the SAT score may, for example, understate the achievement and full potential of East Asians of Taiwanese, Japanese, Korean and Han Chinese descent. If the exam was redesigned to increase score variance (add harder and easier questions than it currently has), the achievement gap across racial groups could be even more wider and pronounced. In other words, if the math section was scored between 0 and 1000, we might see more complete tails on both the right and the left. More East Asians score between 750 and 800 than score between 700 and 750, suggesting that many East Asians of Taiwanese, Japanese, Korean and Han Chinese descent could be scoring high above 800 if the test allowed them to.

College enrollment and graduation rates

The US Department in Education demonstrates performance of different ethnic groups in colleges and universities. Specifically, they found that about 72% of White students who have completed high school enrolled in college the same year, compared to 44% for Black students, and 50% for Hispanic students. Furthermore, trends in undergraduate and graduate enrollment have shown increases in all ethnicity groups, but the largest gap still exists for Black student enrollment. Hispanic and Asian/Pacific Islanders student enrollment have experienced the most growth since 1976. The 6-year national college graduation rate is 59% for White students, 51% for Hispanic students, 46% for Black females, and 35% for Black males. Furthermore, even at prestigious institutions, the graduation rate of white students is higher than that of black student.

Long-term trends

The National Assessment of Educational Progress (NAEP) has been testing seventeen-year-olds since 1971. From 1971 to 1996, the black-white reading gap shrank by almost one half and the math gap by almost one third. Specifically, blacks scored an average of 239 points, and whites scored an average of 291 points on the NAEP reading tests in 1971. In 1990, blacks scored an average of 267, and whites scored an average of 297 points. On NAEP math tests in 1973, blacks scored an average of 270, and whites scored 310. In 1990, black average score was 289 and whites scored an average of 310 points. For Hispanics, the average NAEP math score for seventeen-year-olds in 1973 was 277 and 310 for whites. In 1990, the average score among Hispanics was 284 compared with 310 for whites.

Because of small population size in the 1970s, similar trend data are not available for Asian Americans. Data from the 1990 NAEP Mathematics Assessment Tests show that among twelfth graders, Asians scored an average of 315 points compared with 301 points for whites, 270 for blacks, 278 for Hispanics, and 290 for Native Americans. Racial and ethnic differentiation is most apparent at the highest achievement levels. Specifically, 13% of Asians performed at level of 350 points or higher, 6% of whites, less than 1% of blacks, and 1% of Hispanics did so.

The NAEP has since collected and analyzed data through 2008. Overall, the White-Hispanic and the White-Black gap for NAEP scores have significantly decreased since the 1970s.[23] The Black-White Gap demonstrates:
  • In mathematics, the gap for 17-year-olds was narrowed by 14 points from 1973 to 2008.
  • In reading, the gap for 17-year-olds was narrowed by 24 points from 1971 to 2008.
The Hispanic-White Gap demonstrates:
  • In mathematics, the gap for 17-year-olds was narrowed by 12 points from 1973 to 2008.
  • In reading, the gap for 17-year-olds was narrowed by 15 points from 1975 to 2008.
Furthermore, subgroups showed predominant gains in 4th grade at all achievement levels. In terms of achieving proficiency, gaps between subgroups in most states have narrowed across grade levels, yet had widened in 23% of instances. The progress made in elementary and middle schools was greater than that in high schools, which demonstrates the importance of early childhood education. Greater gains were seen in lower-performing subgroups rather than in higher-performing subgroups. Similarly, greater gains were seen in Latino and African American subgroups than for low-income and Native American subgroups.

Income

Research that was conducted shows that income is a factor that affects the racial achievement gap. Black and Hispanic students tend to come from low-income communities and they also tend to be behind white students in terms of math and reading scores. Another piece of evidence is that when you compare the gap between white and minority students with similar family economic backgrounds, the achievement gap results are different.Katherine Paschall is a researcher who believes that family income plays more of a factor in the academic achievement gap than race/ethnicity. This is due to the fact that even within racial groups, there are differences in economic statuses. Family income was able to explain most of the evidence that was shown. Katherine Paschall conducted research to see if the achievement gap is due to a combination of race/ethnicity and income rather than just race/ethnicity by itself. Paschall discuses how important it is to look at both race/ethnicity and poverty status together. Since there is already research on both factors separately, it is important to look at the intersection between them in order to further understand the achievement gap. Paschall believes that these findings are important in the development of educational policies that try to reduce the achievement gaps.

Theories about the origin of the racial achievement gap

The achievement gap between low-income minority students and middle-income White students has been a popular research topic among sociologists since the publication of the report, "Equality of Educational Opportunity" (more widely known as the Coleman Report). This report was commissioned by the U.S. Department of Education in 1966 to investigate whether the performance of African-American students was caused by their attending schools of a lesser quality than white students. The report suggested that both in-school factors and home/community factors affect the academic achievement of students and contribute to the achievement gap that exists between races.

The study of the achievement gap can be addressed from two standpoints—from a supply-side and a demand-side viewpoint of education. In Poor Economics, Banerjee and Duflo explain the two families of arguments surrounding education of underserved populations. Demand-side arguments focus on aspects of minority populations that influence education achievement. These include family background and culture, which shape perceptions and expectations surrounding education. A large body of research has been dedicated to studying these factors contributing to the achievement gap. Supply-side arguments focus on the provision of education and resources and the systemic structures in place that perpetuate the achievement gap. These include neighborhoods, funding, and policy. In 2006, Ladson-Billings called on education researchers to move the spotlight of education research from family background to take into account the rest of the factors that affect educational achievement, as explained by the Coleman Report. The concept of opportunity gaps—rather than achievement gaps—has changed the paradigm of education research to assess education from a top-down approach.

Non-Cognitive Factors

Social Belonging

A person’s sense of social belonging is one non-cognitive factor that plays a part in the racial achievement gap. Some of the processes that threaten a person’s sense of belonging in schools include social stigma, negative intellectual stereotypes, and numeric under-representation.

Walton and Cohen describe three ways in which a sense of social belonging boosts motivation, the first being positive self-image. By adopting similar interests as those who a person considers to be socially significant, it may help to increase or affirm a person’s sense of his or her personal worth. People have a basic need to belong, which is why people may feel a sense of distress when social rejection occurs. Students in minority groups have to battle other factors as well, such as peer and friend groups being separated by race. Homogeneous friend groups can segregate people out of important networking connections, thus limiting important future opportunities that non-minority groups have because they have access to these networking connections.

Students who do not fall into the majority or dominant group in their schools often worry about whether or not they will belong and find a valued place in their school. Their thoughts are often centered around whether they will be accepted and valued for who they are around their peers. Social rejection can cause reductions in IQ test performance, self-regulation, and also can prompt aggression. People can do more together than they can alone. Social life is a form of collaborative activity, and an important feature of human life. When goals and objectives become shared, they offer a person and the social units he or she is a part of major advantages over if he or she was working alone.

Under performing groups in schools often report that they feel like they do not belong and that they are unhappy a majority of the time. Steele offers an example, explaining an observation done by his colleague, Treisman. It was observed that African American students at Berkeley did their work independently in their rooms with nobody to converse with. They spent most of their time checking answers to their arithmetic in the back of their textbook, weakening their grasp of the concepts themselves. This ultimately caused these students to do worse on tests and assessments than their white peers, creating a frustrating experience and also contributing to the racial achievement gap.
Purpose
When students feel that what they are doing has purpose, they are more likely to succeed academically. Students who identify and actively work towards their individual, purposeful, life goals have a better chance at eliminating disengagement that commonly occurs in middle school and continues into later adolescence. These life goals give students a chance to believe that their school work is done in hopes of achieving larger, more long-term goals that matter to the world. This also gives students the opportunity to feel that their lives have meaning by working towards these goals.

Purposeful life goals, such as work goals, may also increase students motivation to learn. Adolescents may make connections between what they are learning in school and how they will use those skills and knowledge will help them make an impact in the future. This idea ultimately will lead students to create their own goals related to mastering the material they are learning in school.

Adolescents who have goals, and believe that their opinions and voices can impact the world positively, they may become more motivated. They become more committed to mastering concepts and being accountable for their own learning, rather than focusing on getting the highest grade in the class. Students will study more intently and deeply, as well as persist longer, seeking out more challenges. They will like learning more because the tasks they are doing have purpose, creating a personal meaning to them and in turn leading to satisfaction.
Mindset
Students’ mindsets (how they perceive their abilities) play a large role in their achievement and also their motivation. An adolescent's level of self-efficacy is a great predictor of their level of academic performance, going above and beyond a student's measured level of ability and also their prior performance in school. Students having a growth mindset believe that their intelligence can be developed over time. Those with a fixed mindset believe that their intelligence is fixed and cannot grow and develop. Students with growth mindsets tend to outperform their peers who have fixed mindsets.

Students are highly influenced by their teachers in which kind of mindset they develop in school. When people are taught with a growth mindset, the ideas of challenging themselves and putting in more effort follow. People believe that each mindset is better than the other, which causes students to feel that they are not as good as other students in school. A big question that is asked in schooling is when does someone feel smart: when they are flawless or when they are learning? With a fixed mindset, you must be flawless, and not just smart in the classroom. With this mindset, there is even more pressure on students to not only succeed, but to be flawless in front of their peers.

Students who have a fixed mindset, have come to change the idea of failure as an action to an identity. They come to think of the idea of failing something as being that they are a failure and that they cannot achieve something. This links back into how they think of themselves as a person and decreases their motivation in school. This sense of "failure" is especially prominent during adolescence. If one thing goes wrong, one with a fixed mindset will feel that they cannot overcome this small failure, and thus their mindset motivation will decrease.

Education Debt

Education debt is a theory developed by Gloria Ladson-Billings, a pedagogical theorist.  In her theory of education debt, she likens the focus of the achievement gap to the United States current focus on the national deficit. She argues that instead the true issue is debt rather than deficit: an education debt to African Americans, Native Americans, and Latino/as.  As defined by a colleague of Ladson-Billings, Professor Emeritus Robert Haveman, education debt is the “foregone schooling resources that we could have (should have) been investing in (primarily) low income kids, which deficit leads to a variety of social problems (e.g. crime, low productivity, low wages, low labor force participation) that require on-going public investment”. The education debt has historical, economic, sociopolitical and moral components; the structure of the education debt theory makes is a logical cause of the racial achievement gap.   

Historical Component

Historical debt is the concept of inequality throughout history that has prevented equal education of minorities.  Inequities surrounding education throughout history have been designed to prevent people based on their race, class, and gender from receiving quality education.  Disparity in achievement is a result of legislation that has prevented education of minorities, specifically African Americans.  After the abolishment of slavery, African Americans were subject to follow the laws of their bitter oppressors.  This left African Americans with little to no representation.  It was prohibited by law in many places across the United States, specifically the south, for African Americans to attend school. This is an early example in history of education being denied to African Americans.  Similarly, the Native American population was prevented from obtaining a quality education.  After forced labor and genocides, the remaining population was funneled into boarding schools focused on religious teachings and assimilation into European culture. Native Americans had little to no representation. Latino/as were also denied equal education.  In the case Mendez vs. West Minister, Latino fathers challenged the courts as their children, and thousands of others, were victims of racial segregation. Historically, much of the inequalities embedded within legislation was perpetuated by leaders of the country.  The falsity that African Americans were unable to be educated was endorsed by Thomas Jefferson, even though he supported the idea of education for all American people.  Historic events and legislation are both related to economic debt, in the fact that they both affected the education opportunities of minorities.

Economic Component

Economic debt has greatly accumulated from the disparities in school funding.  Even after it was deemed unconstitutional for education to be withheld on the basis of race, legislation regarding the allocation of money for public schools was passed regardless of the fact that it left minority school districts with significantly less money than districts of White counterparts.  The concept of separate but equal, made constitutional by Plessy vs. Ferguson, allowed a significant of amount of funding disparity to be perpetuated.  Although, Plessy vs. Ferguson was overturned, the segregation it caused can still be observed today.  Statistics show that Chicago public school spend spend roughly $8,000 a year per child; the population of Chicago public school students is 87% African American and Latino/a. Highland Park school district spends more than double the amount of the Chicago public school district; Highland Park (a neighboring town) public schools has a population of 91% White students. It is important to consider an affect of economic debt; earning ratios. Gloria Ladson-Billings points to the relation of level of schoolings and earning ratios. Higher level of income is related to a higher level of education data suggests.    

Sociopolitical Component

Sociopolitical debt “is the degree to which communities of color are excluded from the civic process” (Landson-Billings 2006). The civic process includes refers to the engagement of conversation or activity that addresses issues or concerns within society. Disenfranchisement of voting rights contributed to and continues to contribute to sociopolitical debt.  With little to no access to franchise, African American, Latino/a, and Native American communities received no representation or legislation that reflected their issues and concerns.  These groups were often excluded from legislation and conversation concerning education which did not allow them to advocate for the equal education. An example of the mitigation of sociopolitical debt is the Voting Rights Act of 1965.  This piece of legislation ensured a voice to minorities within the political sphere.  No such legislation has been passed that focuses on diminishing education inequalities. Affirmative action is the closest legislation that has had a strong impact. Although affirmative action benefited White women the most, observations show that the emergence of the Black middle class was aided by the policy (Bowen and Bok 1999). Members of the Black middle class  and other minority groups continue to fight for change in education despite being silenced. The sociopolitical debt has limited access to resources such as policy makers and law experts; disadvantages as these do not allow for the gain of political capital needed to enact change.

Moral Component

Moral debt is the final component of the education debt and “reflects disparity between what we know is right and what we actually do” (Ladson-Billings). Moral debt is expressed as the lack of honor given when honor is due.  There is no hesitation in giving honor to Martin Luther King Jr. or Rosa Parks. Another example of repaying moral debt are the reparations placed on Germany after WWII. Debate is happening on the basis of moral debt, reparations and success but much of the debate focuses on the individual and the responsibility of the individual to ensure success.  “No nation can enslave a race of people for hundreds of years, set them free bedraggled and penniless, pit them, without assistance in a hostile environment, against privileged victimizers, and then reasonably expect the gap between the heirs of the two groups to narrow. Lines, begun parallel and left alone, can never touch.” Randall Robinson states.  Individual responsibility becomes an unrealistic expectation when a group has been exploited, disenfranchised and oppressed for centuries.

Family structure/parenting style

Children can differ in their readiness to learn before they enter school. Research has shown that parental involvement in a child's development has a significant effect on the educational achievement of minority children. According to sociologist Annette Lareau, differences in parenting styles can affect a child's future achievement. In her book Unequal Childhoods, she argues that there are two main types of parenting: concerted cultivation and the achievement of natural growth.
  • Concerted cultivation is usually practiced by middle-class parents, regardless of their race. These parents are more likely to be involved in their children's education, encourage their children's participation in extracurricular activities or sports teams, and to teach their children how to successfully communicate with authority figures. These communication skills give children a form of social capital that help them communicate their needs and negotiate with adults throughout their life.
  • The achievement of natural growth is generally practiced by poor and working-class families. These parents generally do not play as large a role in their children's education, their children are less likely to participate in extracurriculars or sports teams, and they usually do not teach their children the communication skills that middle- and upper-class children have. Instead, these parents are more concerned that their children obey authority figures and have respect for authority, which are two characteristics that are important to have in order to succeed in working-class jobs.
The parenting practices that a child is raised with influences their future educational achievement. However, parenting styles are heavily influenced by the parents' and family's social, economic, and physical circumstances. In particular, immigration status (if applicable), education level, incomes, and occupations influence the degree of parental involvement their children's academic achievement. These factors directly determine the access of the parents to time and resources to dedicate to their children's development. These factors also indirectly determine the home environment and parents' educational expectations of their children. For example, children from poor families have lower academic performance in kindergarten than children from middle to upper-class backgrounds, but children from poor families who had cognitively stimulating materials in the home demonstrated higher rates of academic achievement in kindergarten. Additionally, parents of children living in poverty are less likely to have cognitively stimulating materials in the home for their children and are less likely to be involved in their child's school. The quality of language that the student uses is affected by family’s socioeconomic backgrounds, which is another factor in the academic achievement gap.

In the United States, most minority groups are more likely to live in poverty than White Americans. Unemployment rate and mortgages for African and Latin Americans are usually higher than White Americans'. And although Asian American families earn, on average, more income than White American families do, there are usually more family members working in the Asian American family than the White American family. These disparities in socioeconomic status between minority groups and White Americans help explain differences in parenting styles, family structure, and the resultant educational achievement of minority children. However, the racial gaps persists when comparing families with similar income. Whites from families with incomes below $10,000 had a mean SAT test score that was 61 points higher than blacks whose families had incomes of between $80,000 and $100,000.
African-American family structure
In 2010, 72% of Black babies were born to unwed mothers.

There is consensus in the literature about the negative consequences of growing up in single-parent homes on educational attainment and success. Children growing up in single-parent homes are more likely to not finish school and generally obtain less years of schooling than those in two-parent homes. Specifically, boys growing in homes with only their mothers are more likely to receive poorer grades and display behavioral problems.

For black high school students, the African American family structure does affect their educational goals and expectations also. Studies on the topic have indicated that children growing up in single-parent homes faces disturbances in young childhood, adolescence and young adulthood as well. Although these effects are sometimes minimal and contradictory, it is generally agreed that the family structure a child grows up in is important for their success in the educational sphere.

The black family structure is seen as a source of low student achievement because it is seen as a family structure that creates a “culture of poverty”. Research has found that student’s that come from “culture of poverty” tend to be low achievers due to them already being at a disadvantage, making it hard for them to be high achievers.

Cultural differences

Some experts believe that cultural factors contribute to the racial achievement gap. Students from minority cultures face language barriers, differences in cultural norms in interactions, learning styles, varying levels of receptiveness of their culture to White American culture, and varying levels of acceptance of the White American culture by the students. In particular, it has been found that minority students from cultures with views that generally do not align with the mainstream cultural views have a harder time in school. Furthermore, views of the value of education differ by minority groups as well as members within each group. Both Hispanic and African-American youths often receive mixed messages about the importance of education, and often end up performing below their academic potential.
Latino American
Many Hispanic parents who immigrate to The United States see a high school diploma as being a sufficient amount of schooling and may not stress the importance of continuing on to college. Parental discouragement from pursuing higher education tends to be based on the notion of "we made it without formal schooling, so you can too". Additionally, depending on the immigration generation and economic status of the student, some students prioritize their obligations to assisting their family over their educational aspirations. Poor economic circumstances place greater pressure on the students to sacrifice time spent working towards educational attainment in order to dedicate more time to help support the family. Surveys have shown that while Latino American families would like their children to have a formal education, they also place high value on getting jobs, marrying, and having children as early as possible, all of which conflict with the goal of educational achievement. However, counselors and teachers usually promote continuing on to college. This message conflicts with the one being sent to Hispanic students by their families and can negatively affect the motivation of Hispanic students, as evidenced by the fact that Latinos have the lowest college attendance rates of any racial/ethnic group. Overall, Latino American students face barriers such as financial stability and insufficient support for higher education within their families. Reading to children when they are younger increases literacy comprehension, which is a fundamental concept in the education system; however, it is less likely to occur within Latino American families because many parents do not have any formal education. Currently, Latino Americans over the age of 25 have the lowest percentage in obtaining a bachelor's degree or higher amongst all other racial groups; while only having 11 percent.
African American
African American students are also likely to receive different messages about the importance of education from their peer group and from their parents. Many young African-Americans are told by their parents to concentrate on school and do well academically, which is similar to the message that many middle-class white students receive. However, the peers of African-American students are more likely to place less emphasis on education, sometimes accusing studious African-American students of "acting white." This causes problems for black students who want to pursue higher levels of education, forcing some to hide their study or homework habits from their peers and perform below their academic potential.
Asian American
Asian American students are more likely to view education as a means to social mobility, as they believe it provides a means to overcome language barriers as well as discrimination. This notion comes from parental expectations of their children, which are rooted in the cultural belief that hard work is the key to educational and eventually occupational attainment. Many Asian Americans immigrated to the United States voluntarily, in search for better opportunities. This immigration status comes into play when assessing the cultural views of Asian Americans since attitudes of more recent immigration are associated with optimistic views about the correlation between hard work and success. Obstacles such as language barriers and acceptance of White American culture are more easily overcome by voluntary immigrants since their expectations of attaining better opportunities in the United States influence their interactions and experiences.

Geographic and neighborhood factors

The quality of school that a student attends and the socioeconomic status of the student's residential neighborhood are two factors that can affect a student's academic performance.

In the United States, the financing of most public schools is based on local property taxes This system means that schools located in areas with lower real estate values have proportionately less money to spend per pupil than schools located in areas with higher real estate values. This system has also maintained a "funding segregation:" because minority students are much more likely to live in a neighborhood with lower property values, they are much more likely to attend a school that receives significantly lower funding.

Data from research shows that when the quality of the school is better and students are given more resources, it affects the racial achievement gap by reducing it. When white and black schools were given the equal amount of resources, it shows that black students started improving while white students stayed the same because they didn’t need the resources. This showed that lack of resources is a factor in the racial achievement gap. The research that was conducted shows that predominantly white schools have more resources than black schools. However, lack of resources is only a small effect on academic achievement in comparison to students’ family backgrounds.

Using property taxes to fund public schools contributes to school inequality. Lower-funded schools are more likely to have (1) lower-paid teachers; (2) higher student-teacher ratios, meaning less individual attention for each student; (3) older books; (4) fewer extracurricular activities, which have been shown to increase academic achievement; (5) poorly maintained school buildings and grounds; and (6) less access to services like school nursing and social workers. All of these factors can affect student performance and perpetuate inequalities between students of different races.

Living in a high-poverty or disadvantaged neighborhood have been shown to negatively influence educational aspirations and consequently attainment. The Moving to Opportunity experiment showed that moving to a low-poverty neighborhood had a positive effect on the educational attainment of minority adolescents. The school characteristics associated with the low-poverty neighborhoods proved to be effective mediators, since low-poverty neighborhoods tended to have more favorable school composition, safety, and quality. Additionally, living in a neighborhood with economic and social inequalities leads to negative attitudes and more problematic behavior due to and social tensions. Greater college aspirations have been correlated with more social cohesiveness among neighborhood youth, since community support from both youth and adults in the neighborhood tends to have a positive influence on educational aspirations. Some researchers believe that vouchers should be given to low income students so they can go to school in other places. However, other researchers believe that the idea of vouchers promotes equality and doesn’t eliminate it.

Racial and ethnic residential segregation in the United States still persists, with African Americans experiencing the highest degree of residential segregation, followed by Latino Americans and Asian Americans and Pacific Islanders. This isolation from White American communities is highly correlated with low property values and high-poverty neighborhoods. This issue is propagated by issues of home ownership facing minorities, especially African Americans and Latino Americans, since residential areas predominantly populated by these minority groups are perceived as less attractive in the housing market. Home ownership by minority groups is further undermined by institutionalized discriminatory practices, such as differential treatment of African Americans and Latino Americans in the housing market compared with White Americans. Higher mortgages charged to African American or Latino American buyers make it more difficult for members of these minority groups to attain full home ownership and accumulate wealth. As a result, African American and Latino American groups continue to live in racially segregated neighborhoods and face the socioeconomic consequences of residential segregation.

Differences in the academic performance of African-American and White students exist even in schools that are desegregated and diverse, and studies have shown that a school's racial mix does not seem to have much effect on changes in reading scores after sixth grade, or on math scores at any age. In fact, minority students in segregated-minority schools have more optimism and greater educational aspirations as well as achievements than minority students in segregated-white schools. This can be attributed to various factors, including the attitudes of faculty and staff at segregated-white schools and the effect of stereotype threat.

History

The minority status of a student plays a major role in the minority experience of schooling. Non-White minority groups are classified into voluntary and involuntary minority groups, which are differentiated by the reasons that brought the groups to the United States. Voluntary minorities are immigrants who came to the United States for better social, economic, and political opportunities, such as the Chinese and Punjabi Indians. Optimism regarding educational and occupational prospects are reflected in parents' expectations of their children. It should be noted, however, that earlier generations of students from voluntary minority groups tend to perform better and place a higher value on education than native-born and later-generation students of the same group. Involuntary minorities are those from groups who came to the United States or integrated into the United States against their will, such as Native Americans or African Americans. Involuntary minority groups face both external and internal tensions; institutionalized socioeconomic factors prevent social mobility for these groups, in addition to the identity-related conflicts within a minority culture. These ethnic histories thus define the social status of minority groups and thereby influence the schooling experience of minority students.
Legacy of discrimination argument
An argument has been put that the disparity in income that exists between African Americans and Whites directly contributes to the racial achievement gap. This school of thought argues that the origin of this "wealth gap" is the slavery and racism that made it extremely difficult for African-Americans to accumulate wealth for almost 100 years. A comparable history of discrimination created a similar gap between Hispanics and whites. This results in many minority children being born into low socioeconomic backgrounds, which in turn affects educational opportunities.

Research has shown time and again that the wealth and income of parents is a primary factor influencing student achievement. A low socioeconomic background can have negative effects on a child's educational achievement before even starting school; indeed, research has shown that the achievement gap is present between races before starting formal education. On average, when entering kindergarten, African-American students are one year behind White students in terms of vocabulary and basic math skills, and this gap continues to grow as a child's education continues.
Refugees
Part of the racial achievement gap can be attributed to the experience of the refugee population in the United States. Refugee groups in particular face obstacles such as cultural and language barriers and discrimination, in addition to premigration stresses. These factors affect how successfully refugee children can assimilate to and succeed in the United States. Furthermore, it has been shown that immigrant children from politically unstable countries do not perform as well as immigrant children from politically stable countries.

Genetic differences

J. Philippe Rushton and Arthur Jensen suggested that the results of intelligence testing demonstrate that genetic differences can explain some or all of the racial achievement gap in American education.

Robert Sternberg later published a reply to Rushton and Jensen in which he wrote critically of their approach to the subject and of some of their specific claims and rhetoric. Sternberg states his belief that science should be conducted with values in mind. He then argues that Rushton and Jensen were wrong to suggest any policy implications of their research because international variation in social norms and definitions of success may affect the influence IQ has on the attainment of success. While Sternberg acknowledges that there is a genetic factor affecting individual intelligence, he asserts that intelligence is changeable, and at the group level, subjective.

Implications of the achievement gap

Economic outcomes

The racial achievement gap has consequences on the life outcomes of minority students. However, this gap also has the potential for negative implications for American society as a whole, especially in terms of workforce quality and the competitiveness of the American economy. As the economy has become more globalized and the United States' economy has shifted away from manufacturing and towards a knowledge-based economy; education has become an increasingly important determinate of economic success and prosperity. A strong education is now essential for preparing and training the future workforce that is able to compete in the global economy. Education is also important for attaining jobs and a stable career, which is critical for breaking the cycle of poverty and securing a sound economic future, both individually and as a nation. Students with lower achievement are more likely to drop out of high school, entering the workforce with minimal training and skills, and subsequently earning substantially less than those with more education. Therefore, eliminating the racial achievement gap and improving the achievement of minority students will help eliminate economic disparities and ensure that America's future workforce is well prepared to be productive and competitive citizens.

Reducing the racial achievement gap is especially important because the United States is becoming an increasingly diverse country. The percentage of African-American and Hispanic students in school is increasing: in 1970, African-Americans and Hispanics made up 15% of the school-age population, and that number had increased to 30% by 2000. It is expected that minority students will represent the majority of school enrollments by 2015. Minorities make up a growing share of America's future workforce; therefore, the United States' economic competitiveness depends heavily on closing the racial achievement gap.

The racial achievement gap affects the volume and quality of human capital, which is also reflected through calculations of GDP. The cost of racial achievement gap accounts for 2–4 percent of the 2008 GDP. This percentage is likely to increase as blacks and Hispanics continue to account for a higher proportion of the population and workforce. Furthermore, it was estimated that $310 billion would be added to the US economy by 2020 if minority students graduated at the same rate as white students. Even more substantial is the narrowing of educational achievement levels in the US compared to those of higher-achieving nations, such as Finland and Korea. McKinsey & Company estimate a $1.3 trillion to $2.3 trillion, or a 9 to 16 percent difference in GDP. Furthermore, if high school dropouts were to cut in half, over $45 billion would be added in savings and additional revenue. In a single high school class, halving the dropout rate would be able to support over 54,000 new jobs, and increase GDP by as much as $9.6 billion. Overall, the cost of high school drop outs on the US economy is roughly $355 billion.

$3.7 billion would be saved on community college remediation costs and lost earnings if all high school students were ready for college. Furthermore, if high school graduation rates for males raised by 5 percent, cutting back on crime spending and increasing earnings each year would lead to an $8 billion increase the US economy.

Job opportunities

As the United States' economy has moved towards a globalized knowledge-based economy, education has become even more important for attaining jobs and a stable career, which is critical for breaking the cycle of poverty and securing a sound economic future. The racial achievement gap can hinder job attainment and social mobility for minority students. The United States Census Bureau reported $62,545 as the median income of White families, $38,409 of Black families, and $39,730 for Hispanic families. And while the median income of Asian families is $75,027, the number of people working in these households is usually greater than that in White American families. The difference in income levels relate highly to educational opportunities between various groups. Students who drop out of high school as a result of the racial achievement gap demonstrate difficulty in the job market. The median income of young adults who do not finish high school is about $21,000, compared to the $30,000 of those who have at least earned a high school credential. This translates into a difference of $630,000 in the course of a lifetime. Students who are not accepted or decide not to attend college as a result of the racial achievement gap may forgo over $450,000 in lifetime earnings had they earned a Bachelor of Arts degree. In 2009, $36,000 was the median income for those with an associate degree was, $45,000 for those with a bachelor's degree, $60,000 for those with a master's degree or higher.

Stereotype threat

Beyond differences in earnings, minority students also experience stereotype threat that negatively affects performance through activation of salient racial stereotypes. The stereotype threat both perpetuates and is caused by the achievement gap. Furthermore, students of low academic performance demonstrate low expectations for themselves and self-handicapping tendencies. Psychologists Claude Steele, Joshua Aronson, and Steven Spencer, have found that Microaggression such as passing reminders that someone belongs to one group or another (i.e.: a group stereotyped as inferior in academics) can affect test performance.

Steele, Aronson and Spencer, have examined and performed experiments to see how stereotypes can threaten how students evaluate themselves, which then alters academic identity and intellectual performance. Steele tested the stereotype threat theory by giving Black and White college students a half-hour test using difficult questions from the verbal Graduate Record Examination (GRE). In the stereotype-threat condition, they told students the test diagnosed intellectual ability. In saying that the test diagnoses intellectual ability it can potentially elicit the stereotype that Blacks are less intelligent than Whites. In the no-stereotype-threat condition, they told students that the test was a problem-solving lab task that said nothing about ability. This made stereotypes irrelevant. In the stereotype threat condition, Blacks who were evenly matched with Whites in their group by SAT scores, performed worse compared to their White counterparts. In the experiments with no stereotype threat, Blacks performed slightly better than in those with a stereotype threat, though still significantly worse than whites. Aronson believes the study of stereotype threat offers some "exciting and encouraging answers to these old questions [of achievement gaps] by looking at the psychology of stigma -- the way human beings respond to negative stereotypes about their racial or gender group". When pressed, Steele, Aronson, and Spenser, acknowledge that their experiments on stereotype threat only explain a modest portion of test-score gaps. However, their findings have consistently been erroneously attributed to explaining the entirety of the test score gap. The American Psychological Association is one such institution that misuses the study to posit that stereotype threat undercuts the tendency of evolutionary psychologists to lay the blame on genetic and cultural factors, such as whether African Americans "value" education. Researchers from Heterodox Academy, a think tank dedicated to pursuing intellectual diversity in academia, posit that the tendency of some social scientists to over emphasise the potency of stereotype threat, has to do with their loyalty to politically correct clean slate ideology, rather than objective reasoning. Adherence to such dogma therefore permits these individuals to dismiss the possibility of less palatable explanations for racial group disparities, such as genetics and culture.

Political representation

Another consequence of the racial achievement gap can be seen in the lack of representation of minority groups in public office. Studies have shown that higher socioeconomic status—in terms of income, occupation, and/or educational attainment—is correlated with higher participation in politics. This participation is defined as "individual or collective action at the national or local level that supports or opposes state structures, authorities, and/or decisions regarding allocation of public goods"; this action ranges from engaging in activities such as voting in elections to running for public office.

Since median income per capita for minority groups is lower than that of White Americans, and since minority groups are more likely to occupy less gainful employment and achieve lower education levels, there is a lowered likelihood of political participation among minority groups. Education attainment is highly correlated with earnings and occupation. And there is a proven disparity between educational attainment of White Americans and minority groups, with only 30% of bachelor's degrees awarded in 2009 to minority groups. Thus socioeconomic status—and therefore political participation—is correlated with race. Research has shown that African Americans, Latino Americans, and Asian Americans are less politically active, by varying degrees, than White Americans.

A consequence of underrepresentation of minority groups in leadership is incongruence between policy and community needs. A study conducted by Kenneth J. Meier and Robert E. England of 82 of the largest urban school districts in the United States showed that African American membership on the school board of these districts led to more policies encouraging more African American inclusion in policy considerations. It has been shown that both passive and active representation of minority groups serves to align constituent policy preference and representation of these opinions, and thereby facilitate political empowerment of these groups.

Special programs

Achievement gaps among students may also manifest themselves in the racial and ethnic composition of special education and gifted education programs. Typically, African American and Hispanic students are enrolled in greater numbers in special education programs than their numbers would indicate in most populations, while these groups are underrepresented in gifted programs.Research shows that these disproportionate enrollment trends may be a consequence of the differences in educational achievement among groups.

Efforts to narrow the achievement gap

The United States has seen a variety of different attempts to narrow the racial achievement gap. These attempts include focusing on the importance of early childhood education, using federal standards based reforms, and implementing institutional changes.

Early childhood education

There are large cognitive and emotional gaps that form at early ages. They persist throughout childhood and strongly influence adult outcomes. The gaps originate before formal schooling begins and persists through childhood and into adulthood. Remediating the problems created by the gaps is not as cost effective as preventing them at the outset. Eight psychologists performed an experiment of infant children born in Quebec in 1997/1998 and followed annually until 7 years of age. Children receiving formal childcare were distinguished from those receiving informal childcare. Children of mothers with low levels of education showed a consistent pattern of lower scores on academic readiness and achievement tests at 6 and 7 years than those of highly educated mothers, unless they received formal childcare. The findings provide further evidence suggesting that formal childcare could represent a preventative means of attenuating effects of disadvantage on children's early academic trajectory. Economic research shows that investment at this stage is both more effective and cost effective than interventions later in a child's life. An evaluation of Chicago Public Schools' federally funded Child Parent Centers find that for every $1 invested in the preschool program, nearly $11 is projected to return to society over the participants' lifetimes. This amount is equivalent to an 18% annual return.

Head Start Program, Title I of the Elementary and Secondary Education Act (ESEA), and various state-funded pre-kindergarten programs target students from low-income families in an attempt to equal the playing field for these children before school begins. The evidence in favor of investing in early childhood education as a means of closing the achievement gap is strong: various studies have a positive and long-lasting effect on academic achievement of low-income and minority students. Evaluations of Head Start have reported positive results. However, fade-out effects were found in Head Start.

Critics question whether an emphasis on early childhood education will benefit long-term kindergarten through 12th grade learning. Critics point to fade-out effects found in Head Start. Adam Schaeffer, a policy analyst with the Cato Institute highlights research shows that students make some gains in the first two years after preschool but it fades out after. Recent literature also reveals positive, short-term effects of early childhood education on children's development that weaken over time. Even more substantial is the narrowing of educational achievement levels in the US compared to those of higher-achieving nations, such as Finland and Korea. McKinsey & Company estimate a $1.3 trillion to $2.3 trillion, or a 9 to 16 percent difference in GDP. However, Mary Ellen McGuire, an education policy director at think tank New America Foundations, pointed out that early childhood education isn't intended to be a silver-bullet fix to the educational system. It is merely one aspect. In order for those effects to last high-quality early childhood education needs to be connected to high-quality elementary schools.

Standards-based reform

Standards-based reform has been a popular strategy used to try to eliminate the achievement gap in recent years. The goal of this reform strategy is to raise the educational achievement of all students, not just minorities. Many states have adopted higher standards for student achievement. This type of reform focuses on scores on standardized tests, and these scores show that a disproportionate share of the students who are not meeting state achievement standards are Hispanic and African-American.  Therefore, it is not enough for minorities to improve just as much as Whites do—they must make greater educational gains in order to close the gap.

Goals 2000

One example of standards-based reform was Goals 2000, also known as the Educate America Act. Goals 2000 was enacted in 1994 by President Clinton and allowed the federal government a new role in its support for education. It aimed to "provide a framework for meeting the National Education Goals". It was designed to provide resources to states and communities to make sure that all students achieved their full potential by the year 2000. This program set forth eight goals for American students, including all children in America will start school ready to learn, increasing the high school graduation rate to at least 90%, and increasing the standing of American students to first in the world in achievement in math and science. Goals 2000 also placed an emphasis on the importance of technology, promising that all teachers would have modern computers in their classroom and that effective software would be an integral part of the curriculum in every school. President George Bush's No Child Left Behind Act essentially replaced the Goals 2000 program.

No Child Left Behind

The No Child Left Behind Act(NCLB) legislation was signed by President Bush in January 2002 and dramatically expanded federal influence over the nation's more than 90,000 public schools. The main implications of this legislation was states had to conduct annual student assessments linked to state standards to identify schools failing to make "adequate yearly progress" (AYP) toward the stated goal of having all students achieve proficiency in reading and math by 2013–2014 and to institute sanctions and rewards based on each school's AYP status. One of the motivations for this reform is that publicizing detailed information on school-specific performance and linking that "high-stakes" test performance to the possibility of sanctions will improve the focus and productivity of public schools. However, critics charge that test-based school accountability has several negative consequences for the broad cognitive development of children.

Critics argue that NCLB and other test-based accountability policies cause educators to shift resources away from important but non-tested subjects and to focus instruction in math and reading on the relatively narrow set of topics that are most heavily represented on the high-stakes tests. Some even suggest that high-stakes testing may lead school personnel to intentionally manipulate student test scores.

NCLB has shown mixed success in eliminating the racial achievement gap. Although test scores are improving, they are improving equally for all races, which means that minority students are still behind whites. There has also been some criticism as to whether an increase in test scores actually corresponds to improvements in education, since test standards vary from state to state and from year to year.

Institutional changes

Research has shown that making certain changes within schools can improve the performance of minority students. These include lowering class size in schools with a large population of minority students; expanding access to high-quality preschool programs to minority families; and focus on teaching the critical thinking and problem-solving skills that are necessary to retain high-level information.

Charter schools

In the United States there are now 5,042 charter schools serving 1.5 million students in 39 states and Washington, D.C. Although they serve only a fraction of the nation's public school students, charter schools have seized a prominent role in education today. The question of whether charters or traditional public schools do a better job of educating students is still open to debate. The research is highly mixed due the complexities of comparison and wide performance differences among charters.

Charter schools are by definition independent public schools. Although funded with taxpayer dollars, they operate free from many of the laws and regulations that govern traditional public schools. In exchange for that freedom, they are bound to the terms of a contract, or "charter," that lays out a school's mission, academic goals, and accountability procedures. The average charter school enrollment is 372, compared with about 478 in all public schools. Researchers have linked small schools with higher achievement, more individualized instruction, greater safety, and increased student involvement. With their relative autonomy, charter schools are also seen as a way to provide greater educational choice and innovation within the public school system. Another attraction of charter schools is that they often have specialized educational programs. Charters frequently take alternative curricular approaches, emphasize particular fields of study or serve special populations of students. That growth of charter schools has been particularly strong in cities. More than 55 percent of public charter schools were in urban settings.  Some charters have high concentrations of minority students because demand for schooling alternatives is highest among such students, whom they say are often poorly served by the traditional public school systems. Lastly, another positive argument for charter schools is that they improve the existing school systems through choice and competition.

However, there are some criticisms of charter schools. There is a high variability in the quality and success of charter schools across the nation. A high-profile report from the American Federation of Teachers (2002), for example, argued that many charter school authorizers have failed to hold the administrators and teachers accountable, leaving some students to languish in low-performing schools. Another concern of critics is that charters are more racially segregated than traditional public schools, thus denying students the educational "benefits associated with attending diverse schools". Skeptics also worry that charter schools unfairly divert resources and policy attention from regular public schools.

Taken together, studies about charter schools are inconclusive and have mixed results. Studies by the Goldwater Institute and California State University-Los Angeles found that students in charter schools show higher growth in achievement than their counterparts in traditional public schools. However, another study by the Institute of Race and Poverty at the University of Minnesota Law show that after two decades of experience, most charter schools in the Twin Cities still underperform comparable traditional public schools and are highly segregated by race and income.
Non-English schools
To evade a shift to English, some Native American tribes have initiated language immersion schools for children, where a native Indian language is the medium of instruction. For example, the Cherokee Nation instigated a 10-year language preservation plan that involved growing new fluent speakers of the Cherokee language from childhood on up through school immersion programs as well as a collaborative community effort to continue to use the language at home. This plan was part of an ambitious goal that in 50 years, 80% or more of the Cherokee people will be fluent in the language. The Cherokee Preservation Foundation has invested $3 million into opening schools, training teachers, and developing curricula for language education, as well as initiating community gatherings where the language can be actively used. Formed in 2006, the Kituwah Preservation & Education Program (KPEP) on the Qualla Boundary focuses on language immersion programs for children from birth to fifth grade, developing cultural resources for the general public and community language programs to foster the Cherokee language among adults.

There is also a Cherokee language immersion school in Tahlequah, Oklahoma that educates students from pre-school through eighth grade. Because Oklahoma's official language is English, Cherokee immersion students are hindered when taking state-mandated tests because they have little competence in English. The Department of Education of Oklahoma said that in 2012 state tests: 11% of the school's sixth-graders showed proficiency in math, and 25% showed proficiency in reading; 31% of the seventh-graders showed proficiency in math, and 87% showed proficiency in reading; 50% of the eighth-graders showed proficiency in math, and 78% showed proficiency in reading. The Oklahoma Department of Education listed the charter school as a Targeted Intervention school, meaning the school was identified as a low-performing school but has not so that it was a Priority School. Ultimately, the school made a C, or a 2.33 grade point average on the state's A-F report card system. The report card shows the school getting an F in mathematics achievement and mathematics growth, a C in social studies achievement, a D in reading achievement, and an A in reading growth and student attendance. "The C we made is tremendous," said school principal Holly Davis, "[t]here is no English instruction in our school's younger grades, and we gave them this test in English." She said she had anticipated the low grade because it was the school's first year as a state-funded charter school, and many students had difficulty with English. Eighth graders who graduate from the Tahlequah immersion school are fluent speakers of the language, and they usually go on to attend Sequoyah High School where classes are taught in both English and Cherokee.

Private schools

Private schools are another institution used in attempt to narrow the racial achievement gap. A disparity between achievement gaps in private and public schools can be seen using a U.S. Department of Education database to compute the average National Assessment of Educational Progress test score differences between black students and white students in both public and private schools.

NAEP Achievement Differences for Public and Private Schools
NAEP Test Subject Year 4th Grade Gap (Public) 12th Grade Gap (Public) Percent Difference* Between 4th and 12th Grade Gaps (Public) 4th Grade Gap (Private) 12th Grade Gap (Private) Percent Difference* Between 4th and 12th Grade Gaps (Private)
Reading 2002 29 25 -13.8 27 14 -48.1
Writing 2002 20 23 15 22 18 -18.2
Math 2000 30 33 10 28 23 -17.9
Science 2001 35 31 -11.4 27 20 -25.9

The table on White/Black NAEP Achievement Differences for Public and Private Schools above, shows a sizeable achievement gap between black and white fourth-graders in both public and private schools. However, the private-sector achievement gap is narrower in the 12th grade than the fourth grade for all of the core NAEP subjects. Public schools, on the other hand, see a larger gap in both writing and mathematics at the 12th-grade level than at the fourth. Averaged across subjects, the public school racial achievement gap is virtually unchanged between fourth and 12th grades, while the gap in private schools is an average of 27.5 percentage points smaller in the 12th grade than the fourth.

The achievement gap closes faster in private schools not because white private school students lose ground with respect to white public school students as they move to higher grades, but because black private school students learn at a substantially higher rate than black public school students. Economist Derek Neal has found that black students attending urban private schools are far more likely to complete high school, gain admission to college, and complete college than similar students in urban public schools. Similarly, in a study comparing graduation rates of all Milwaukee public school students (of all income levels) with those of the low-income participants in the city's private school voucher program, Manhattan Institute Senior Fellow Jay Greene found the voucher students were more than one-and-a-half-times as likely to graduate as public school students.

However, others argue that private schools actually perpetuate and exacerbate the achievement gap. Without controlling for student background differences, private schools scored higher than public schools. However, a study showed that demographic differences between students in public and private schools more than account for the relatively high scores of private schools. In fact, after controlling for these differences, the advantageous "private school effect" disappears and even reverses in most cases. Private schools have selective acceptance and a different demographic. Another criticism is that private schools only serve a small percent of the population and therefore cannot make a huge effect on closing the achievement gap.

Greg Wiggan believes that although there is a lot of research on the topic of the racial achievement gap, there is a gap in the research. Wiggan believes that the gap that is missing is the research of the perspective of the students, specifically high-achieving Black students in private schools.

Teach For America

Teach for America (TFA) recruits and selects graduates from some of the top colleges and universities across the country to teach in the nation's most challenging K-12 schools throughout the nation. It began in 1990 with 500 teachers and has since expanded to over 4,000 teacher placements in 2010. In the Journal of Policy Analysis and Management they use individual-level student data linked to teacher data in North Carolina to estimate the effects of having a TFA teacher compared to a traditional teacher. According to studies about the effect of different teacher-preparation programs in Louisiana, North Carolina, and Tennessee, TFA is among the most effective sources of new teachers in low-income communities. Each of these statewide studies, conducted between 2009 and 2012, found that corps members often help their students achieve academic gains at rates equal to or larger than those for students of more veteran teachers. The findings show that TFA teachers are in general more effective, according to student exam scores, than traditional teachers that would be in the classroom in their stead. These estimates demonstrate that, compared with traditional teachers with similar levels of experience, TFA teachers have strong positive effects on student test scores. And despite the limitations of TFA teachers, they are no worse than average traditional teachers in teaching math subjects and much more effective in teaching science subjects.

Although TFA teachers tend to have stronger academic credentials, they have not been taught in traditional training programs, are more likely to teach for a few years, and are assigned to some of the most challenging schools in the country. Given these differences, the TFA program has been controversial. Critics of Teach For America point out two of the major problems. The first is that most TFA teachers have not received traditional teacher training. TFA corps members participate in an intensive five-week summer national institute and a two-week local orientation and induction program prior to their first teaching assignment, and therefore some argued they are not as prepared for the demands of the classroom as traditionally trained teachers. The second criticism is that TFA requires only a two-year teaching commitment, and the majority of corps members leave at the end of that commitment. The short tenure of TFA teachers is troubling because research shows that new teachers are generally less effective than more experienced teachers.

Interventions fon Non-Cognitive Factors

Many different types of interventions can be done to help students who are a part of a negative stereotype, but a self-affirmation intervention would be the most helpful for students academic performance. This intervention was expected to help improve a group of students who are at risk to intervene with the group’s academic performance. This intervention was tested in two different double-blind field experiences, and then compared. One of the things seen was that African American students who were a part of the control condition, who saw their performance declining early in the term, their performance did not improve as the term went on, and in fact it got worse. One thing that could lead to a slight improvement is having a small reduction in the psychological threats. Small interventions were seen to have a greater effect when they were carried out in multiple trials, different times. Having just one intervention one time does not have a positive effect on a student, rather if there are multiple smaller interventions carried out different times.

Euthenics

From Wikipedia, the free encyclopedia

Euthenics /jˈθɛnɪks/ is the study of the improvement of human functioning and well-being by improvement of living conditions. Affecting the "improvement" through altering external factors such as education and the controllable environment, including the prevention and removal of contagious disease and parasites, environmentalism, education regarding employment, home economics, sanitation, and housing.
 
Rose Field notes of the definition in a May 23, 1926 New York Times article, "the simplest being efficient living". A right to environment.

The Flynn effect has been often cited as an example of euthenics. Another example is the steady increase in body size in industrialized countries since the beginning of the 20th century.

Euthenics is not normally interpreted to have anything to do with changing the composition of the human gene pool by definition, although everything that affects society has some effect on who reproduces and who does not.

Origin of the term

Ellen Swallow Richards, the first female student and instructor at MIT.

The term was derived in the late 19th century from the Greek verb eutheneo, εὐθηνέω (eu, well; the, root of τίθημι tithemi, to cause).

(To be in a flourishing state, to abound in, to prosper.—Demosthenes. To be strong or vigorous.—Herodotus. To be vigorous in body.—Aristotle.)

Also from the Greek Euthenia, Εὐθηνία. Good state of the body: prosperity, good fortune, abundance.—Herodotus.

The opposite of Euthenia is Penia, Πενία ("deficiency" or "poverty") the personification of poverty and need.

History

Ellen H. Swallow Richards (1842–1911; Vassar Class of '70) was one of the first writers to use the term, in The Cost of Shelter (1905), with the meaning "the science of better living". It is unclear if (and probably unlikely that) any of the study programs of euthenics ever completely embraced Richards' multidisciplinary concept, though several nuances remain today, especially that of interdisciplinarity.

Vassar College Institute of Euthenics

Julia Clifford Lathrop as the first chief of the U.S. Children's Bureau.

After Richards' death in 1911, Julia Lathrop (1858–1932; VC '80)—one of Vassar's most distinguished alumnae—continued to promote the development of an interdisciplinary program in euthenics at the college. Lathrop soon teamed with alumna Minnie Cumnock Blodgett (1862–1931; VC '84), who with her husband, John Wood Blodgett, offered financial support to create a program of euthenics at Vassar College. Curriculum planning, suggested by Vassar president Henry Noble MacCracken in 1922, began in earnest by 1923, under the direction of Professor Annie Louise Macleod (Chemistry; First woman PhD, McGill University, 1910).

According to Vassar's chronology entry for March 17, 1924, "the faculty recognized euthenics as a satisfactory field for sequential study (major). A Division of Euthenics was authorized to offer a multidisciplinary program [radical at the time] focusing the techniques and disciplines of the arts, sciences and social sciences on the life experiences and relationships of women. Students in euthenics could take courses in horticulture, food chemistry, sociology and statistics, education, child study, economics, economic geography, physiology, hygiene, public health, psychology and domestic architecture and furniture. With the new division came the first major in child study at an American liberal arts college."

For example, a typical major in child study in euthenics includes introductory psychology, laboratory psychology, applied psychology, child study and social psychology in the Department of Psychology; the three courses offered in the Department of Child Study; beginning economics, programs of social reorganization and the family in Economics; and in the Department of Physiology, human physiology, child hygiene, principles of public health.

The Vassar Summer Institute of Euthenics accepted its first students in June 1926. Created to supplement the controversial euthenics major which began February 21, 1925, it was also located in the new Minnie Cumnock Blodgett Hall of Euthenics (York & Sawyer, architects; ground broke October 25, 1925). Some Vassar faculty members (perhaps emotionally upset with being displaced on campus to make way, or otherwise politically motivated) contentiously "believed the entire concept of euthenics was vague and counter-productive to women's progress."

Having overcome a lukewarm reception, Vassar College officially opened its Minnie Cumnock Blodgett Hall of Euthenics in 1929. Dr. Ruth Wheeler (Physiology and Nutrition – VC '99) took over as director of euthenics studies in 1924. Wheeler remained director until Mary Shattuck Fisher Langmuir (VC '20) succeeded her in 1944, until 1951.

The college continued for the 1934–35 academic year its successful cooperative housing experiment in three residence halls. Intended to help students meet their college costs by working in their residences. For example, in Main, students earned $40 a year by doing relatively light work such as cleaning their rooms.

In 1951, Katharine Blodgett Hadley (VC '20) donated $400,000, through the Rubicon Foundation, to Vassar to help fund operating deficits in the current and succeeding years and to improve faculty salaries.

"Discontinued for financial reasons, the Vassar Summer Institute for Family and Community Living, founded in 1926 as the Vassar Summer Institute of Euthenics, held its last session, July 2, 1958. This was the first and last session for the institute's new director, Dr. Mervin Freedman."

Elmira College

Elmira College is noted as the oldest college still in existence which (as a college for women) granted degrees to women which were the equivalent of those given to men (the first to do so was the now-defunct Mary Sharp College). Elmira College became coeducational in all of its programs in 1969.

A special article was written in the December 12, 1937 New York Times, quoting recent graduates of Elmira College, urging for courses in colleges for men on the care of children. Reporting that "preparation for the greatest of all professions, that of motherhood and child-training, is being given the students at Elmira College in the Nursery School which is Conducted as part of the Department of Euthenics."

Elmira College was one of the first of the liberal arts colleges to recognize the fact that women should have some special training, integrated with the so-called liberal studies, which would prepare them to carry on, with less effort and fewer mistakes, a successful family life. Courses in nutrition, household economics, clothing selection, principles of foods and meal planning, child psychology, and education in family relations are a part of the curriculum.

The Elmira College nursery school for fifteen children between the ages of two and five years was opened primarily as a laboratory for college students, but it had become so popular with parents in the community that there was always a long waiting list.

The New York Times article notes how the nursery had become one of the essential laboratories of the college, where recent mothers testified to the value of the training they received while in college. "Today," one graduate said, "when it is often necessary for young women to continue professional work outside the home after marriage, it is important that young fathers, who must share in the actual care and training of the children, should have some knowledge of correct methods."

Today

Many factors led to the movement never getting the funding it needed to remain relevant, including: vigorous debate about the exact meaning of euthenics, a strong antifeminism movement paralleling even stronger women's rights movements, confusion with the term eugenics, the economic impact of the Great Depression and two world wars. These factors also prevented the discipline from gaining the attention it needed to put together a lasting, vastly multidisciplinary curriculum. Therefore, it split off into separate disciplines. Child Study is one such curriculum.

Martin Heggestad of the Mann Library notes that "Starting around 1920, however, home economists tended to move into other fields, such as nutrition and textiles, that offered more career opportunities, while health issues were dealt with more in the hard sciences and in the professions of nursing and public health. Also, improvements in public sanitation (for example, the wider availability of sewage systems and of food inspection) led to a decline in infectious diseases and thus a decreasing need for the largely household-based measures taught by home economists." Thus, the end of euthenics as originally defined by Ellen Swallow Richards ensued.

Relationship with eugenics

According to Ellen Richards, in her book Euthenics: the science of controllable environment (1910):
The betterment of living conditions, through conscious endeavor, for the purpose of securing efficient human beings, is what the author means by Euthenics.
"Human vitality depends upon two primary conditions—heredity and hygiene—or conditions preceding birth and conditions during life."
Eugenics deals with race improvement through heredity.
Euthenics deals with race improvement through environment.
Eugenics is hygiene for the future generations.
Euthenics is hygiene for the present generation.
Eugenics must await careful investigation.
Euthenics has immediate opportunity.
Euthenics precedes eugenics, developing better men now, and thus inevitably creating a better race of men in the future. Euthenics is the term proposed for the preliminary science on which Eugenics must be based.

Debate, misconceptions and opposition

Abraham Flexner, c. 1895
 
 

Debate over misconceptions about the movement started almost from the beginning. In his comparison "Eugenics, Euthenics, And Eudemics", (American Journal of Sociology, Vol. 18, No. 6, May 1913), Lester F. Ward of Brown University opens the second section regarding euthenics lamenting:
Is there, then, nothing to do? Are we to accept that modem scientific fatalism known as laissez faire, which enjoins the folding of the arms? Are we to preach a gospel of inaction? I for one certainly am not content to do so, and I believe that nothing I have thus far said [about eugenics] is inconsistent with the most vigorous action, and that in the direction of the betterment of the human race. The end and aim of the eugenists cannot be reproached. The race is far from perfect. Its condition is deplorable. Its improvement is entirely feasible, and in the highest degree desirable. Nor do I refer merely to economic conditions, to the poverty and misery of the disinherited classes. The intellectual state of the world is deplorable, and its improvement is clearly within the reach of society itself. It is therefore a question of method rather than of principle that concerns us.
Ward later noted about the organic environment that:
Darwin has taught us that the chief barrier to the advance of any species of plants or animals is its competition with other plants and animals that contest the same ground. And therefore the fiercest opponents of any species are the members of the same species which demand the same elements of subsistence. Hence the chief form of relief in the organic world consists in the thinning-out of competitors. Any species of animals or plants left free to propagate at its normal rate would overrun the earth in a short time and leave no room for any other species. Any species that is sufficiently vigorous to resist its organic environment will crowd out all others and monopolize the earth. If nature permitted this there could be no variety, but only one monotonous aspect devoid of interest or beauty. Whatever we may think of the harsh method by which this is prevented, we cannot regret that it is prevented, and that we have a world of variety, interest, and aesthetic attractiveness.
Vassar historians note that "critics faulted the new program as a weakening of science and a slide into vocationalism. The influential educator and historian of education, Abraham Flexner—one of the founders of the Princeton Institute for Advanced Study—attacked the program, along with other “ad hoc” innovations like intercollegiate athletics and student governments, in Universities, American, English, German (1930)."


In the summer of 1926, Margaret Sanger created a stir when she gave a radio address, called "Racial Betterment", in the first Euthenics Institute, where she praised attempts to "close our gates to the so-called 'undesirables'" and proposed efforts to "discourage or cut down on the rapid multiplication of the unfit and undesirable at home", by government-subsidized voluntary sterilization. (from The Selected Papers of Margaret Sanger, vol. 1 (2003), Esther Katz, ed.)

Eugenicist, Charles Benedict Davenport, noted in his article "Euthenics and Eugenics," found reprinted in the Popular Science Monthly of January 1911, page 18, 20:
Thus the two schools of euthenics and eugenics stand opposed, each viewing the other unkindly. Against eugenics it is urged that it is a fatalistic doctrine and deprives life of the stimulus toward effort. Against euthenics the other side urges that it demands an endless amount of money to patch up conditions in the vain effort to get greater efficiency. Which of the two doctrines is true?

The thoughtful mind must concede that, as is so often the case where doctrines are opposed, each view is partial, incomplete and really false. The truth does not exactly lie between the doctrines; it comprehends them both. What a child becomes is always the resultant of two sets of forces acting from the moment the fertilized egg begins its development—one is the set of internal tendencies and the other is the set of external influences. What the result of an external influence—a particular environmental condition—shall be depends only in part upon the nature of the influence; it depends also upon the internal nature of the reacting protoplasm.

Incest, cousin marriage, the marriage of defectives and tuberculous persons, are, in wide circles, taboo. This fact affords the basis for the hope that, when the method of securing strong offspring, even from partially defective stock—and where is the strain without any defect?—is widely known, the teachings of science in respect even to marriage matings will be widely regarded and that in the generations to come the teachings and practice of euthenics will yield greater result because of the previous practice of the principles of eugenics.
In a New York Times op-ed dated October 24, 1926, entitled "Eugenics and euthenics", in response to an op-ed entitled "Bright Children Who Fail" which appeared the previous October 15, student of child psychology, Joseph A. Krisses observes:

Flynn effect

From Wikipedia, the free encyclopedia

The Flynn effect is the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that was measured in many parts of the world over the 20th century. When intelligence quotient (IQ) tests are initially standardized using a sample of test-takers, by convention the average of the test results is set to 100 and their standard deviation is set to 15 or 16 IQ points. When IQ tests are revised, they are again standardized using a new sample of test-takers, usually born more recently than the first. Again, the average result is set to 100. However, when the new test subjects take the older tests, in almost every case their average scores are significantly above 100.

Test score increases have been continuous and approximately linear from the earliest years of testing to the present. For the Raven's Progressive Matrices test, a study published in the year 2009 found that British children's average scores rose by 14 IQ points from 1942 to 2008. Similar gains have been observed in many other countries in which IQ testing has long been widely used, including other Western European countries, Japan, and South Korea.

There are numerous proposed explanations of the Flynn effect, as well as some skepticism about its implications. Similar improvements have been reported for other cognitions such as semantic and episodic memory. Research suggests that there is an ongoing reversed Flynn effect, i.e. a decline in IQ scores, in Norway, Denmark, Australia, Britain, the Netherlands, Sweden, Finland, France and German-speaking countries, a development which appears to have started in the 1990s.

Origin of term

The Flynn effect is named for James R. Flynn, who did much to document it and promote awareness of its implications. The term itself was coined by Richard Herrnstein and Charles Murray, authors of The Bell Curve. Although the general term for the phenomenon - referring to no researcher in particular - continues to be "secular rise in IQ scores", many textbooks on psychology and IQ testing have now followed the lead of Herrnstein and Murray in calling the phenomenon the Flynn effect.

Rise in IQ

IQ tests are updated periodically. For example, the Wechsler Intelligence Scale for Children (WISC), originally developed in 1949, was updated in 1974, in 1991, 2003 and again in 2014. The revised versions are standardized based on the performance of test-takers in standardization samples. A standard score of IQ 100 is defined as the median performance of the standardization sample. Thus one way to see changes in norms over time is to conduct a study in which the same test-takers take both an old and new version of the same test. Doing so confirms IQ gains over time. Some IQ tests, for example tests used for military draftees in NATO countries in Europe, report raw scores, and those also confirm a trend of rising scores over time. The average rate of increase seems to be about three IQ points per decade in the United States, as scaled by the Wechsler tests. The increasing test performance over time appears on every major test, in every age range, at every ability level, and in every modern industrialized country, although not necessarily at the same rate as in the United States. The increase was continuous and roughly linear from the earliest days of testing to the mid 1990s. Though the effect is most associated with IQ increases, a similar effect has been found with increases in attention and of semantic and episodic memory.

Ulric Neisser estimated that using the IQ values of 1997, the average IQ of the United States in 1932, according to the first Stanford–Binet Intelligence Scales standardization sample, was 80. Neisser states that "Hardly any of them would have scored 'very superior', but nearly one-quarter would have appeared to be 'deficient.'" He also wrote that "Test scores are certainly going up all over the world, but whether intelligence itself has risen remains controversial."

Trahan et al. (2014) found that the effect was about 2.93 points per decade, based on both Stanford–Binet and Wechsler tests; they also found no evidence the effect was diminishing. In contrast, Pietschnig & Voracek (2015) reported, in their meta-analysis of studies involving nearly 4 million participants, that the Flynn effect had decreased in recent decades. They also reported that the magnitude of the effect was different for different types of intelligence ("0.41, 0.30, 0.28, and 0.21 IQ points annually for fluid, spatial, full-scale, and crystallized IQ test performance, respectively"), and that the effect was stronger for adults than for children.

Raven (2000) found that, as Flynn suggested, data interpreted as showing a decrease in many abilities with increasing age must be re-interpreted as showing that there has been a dramatic increase of these abilities with date of birth. On many tests this occurs at all levels of ability.

Some studies have found the gains of the Flynn effect to be particularly concentrated at the lower end of the distribution. Teasdale and Owen (1989), for example, found the effect primarily reduced the number of low-end scores, resulting in an increased number of moderately high scores, with no increase in very high scores. In another study, two large samples of Spanish children were assessed with a 30-year gap. Comparison of the IQ distributions indicated that the mean IQ-scores on the test had increased by 9.7 points (the Flynn effect), the gains were concentrated in the lower half of the distribution and negligible in the top half, and the gains gradually decreased as the IQ of the individuals increased. Some studies have found a reverse Flynn effect with declining scores for those with high IQ.

In 1987, Flynn took the position that the very large increase indicates that IQ tests do not measure intelligence but only a minor sort of "abstract problem-solving ability" with little practical significance. He argued that if IQ gains do reflect intelligence increases, there would have been consequent changes of our society that have not been observed (a presumed non-occurrence of a "cultural renaissance"). Flynn no longer endorses this view of intelligence and has since elaborated and refined his view of what rising IQ scores mean.

Precursors to Flynn's publications

Earlier investigators had discovered rises in raw IQ test scores in some study populations, but had not published general investigations of that issue in particular. Historian Daniel C. Calhoun cited earlier psychology literature on IQ score trends in his book The Intelligence of a People (1973). R. L. Thorndike drew attention to rises in Stanford-Binet scores in a 1975 review of the history of intelligence testing.

Intelligence

There is debate about whether the rise in IQ scores also corresponds to a rise in general intelligence, or only a rise in special skills related to taking IQ tests. Because children attend school longer now and have become much more familiar with the testing of school-related material, one might expect the greatest gains to occur on such school content-related tests as vocabulary, arithmetic or general information. Just the opposite is the case: abilities such as these have experienced relatively small gains and even occasional decreases over the years. Meta-analytic findings indicate that Flynn effects occur for tests assessing both fluid and crystallized abilities. For example, Dutch conscripts gained 21 points during only 30 years, or 7 points per decade, between 1952 and 1982. But this rise in IQ test scores is not wholly explained by an increase in general intelligence. Studies have shown that while test scores have improved over time, the improvement is not fully correlated with latent factors related to intelligence. Rushton has shown that the gains in IQ over time (the Lynn-Flynn effect) are unrelated to g. Other researchers have shown that the IQ gains described by the Flynn effect are due in part to increasing intelligence, and in part to increases in test-specific skills. In parallel with the measured gains in IQ scores, secular declines have been found for "mental speed, digit span backwards, the use of difficult words, and color acuity, all of which are related to intelligence".

Proposed explanations

A 2017 survey of 75 experts in the field of intelligence research suggested four key causes of the Flynn effect: Better health, better nutrition, more and better education, and rising standards of living. Genetic changes were seen as not important. The experts' views agreed with an independently performed meta-analysis on published Flynn effect data, except that the latter found life history speed to be the most important factor.

The expert survey explained the possible end or decline in the Flynn effect by asymmetric fertility by means of genetic effects, migration, asymmetric fertility by means of socialization effects, declines in education, and the influence of media.

Schooling and test familiarity

Duration of average schooling has increased steadily. One problem with this explanation is that if in the US comparing older and more recent subjects with similar educational levels, then the IQ gains appear almost undiminished in each such group considered individually.

Many studies find that children who do not attend school score drastically lower on the tests than their regularly attending peers. During the 1960s, when some Virginia counties closed their public schools to avoid racial integration, compensatory private schooling was available only for Caucasian children. On average, the scores of African-American children who received no formal education during that period decreased at a rate of about six IQ points per year.

Another explanation is an increased familiarity of the general population with tests and testing. For example, children who take the very same IQ test a second time usually gain five or six points.  However, this seems to set an upper limit on the effects of test sophistication. One problem with this explanation and others related to schooling is that in the US, the groups with greater test familiarity show smaller IQ increases.

Early intervention programs have shown mixed results. Some preschool (ages 3–4) intervention programs like "Head Start" do not produce lasting changes of IQ, although they may confer other benefits. The "Abecedarian Early Intervention Project", an all-day program that provided various forms of environmental enrichment to children from infancy onward, showed IQ gains that did not diminish over time. The IQ difference between the groups, although only five points, was still present at age 12. Not all such projects have been successful. Also, such IQ gains can diminish until age 18.

Citing a high correlation between rising literacy rates and gains in IQ, David Marks has argued that the Flynn effect is caused by changes in literacy rates.

Generally more stimulating environment

Still another theory is that the general environment today is much more complex and stimulating. One of the most striking 20th century changes of the human intellectual environment has come from the increase of exposure to many types of visual media. From pictures on the wall to movies to television to video games to computers, each successive generation has been exposed to richer optical displays than the one before and may have become more adept at visual analysis. This would explain why visual tests like the Raven's have shown the greatest increases. An increase only of particular form(s) of intelligence would explain why the Flynn effect has not caused a "cultural renaissance too great to be overlooked."

In 2001, Dickens and Flynn presented a model for resolving several contradictory findings regarding IQ. They argue that the measure "heritability" includes both a direct effect of the genotype on IQ and also indirect effects such that the genotype changes the environment, thereby affecting IQ. That is, those with a greater IQ tend to seek stimulating environments that further increase IQ. These reciprocal effects result in gene environment correlation. The direct effect could initially have been very small, but feedback can create large differences of IQ. In their model, an environmental stimulus can have a very great effect on IQ, even for adults, but this effect also decays over time unless the stimulus continues (the model could be adapted to include possible factors, like nutrition during early childhood, that may cause permanent effects). The Flynn effect can be explained by a generally more stimulating environment for all people. The authors suggest that any program designed to increase IQ may produce long-term IQ gains if that program teaches children how to replicate the types of cognitively demanding experiences that produce IQ gains outside the program. To maximize lifetime IQ, the programs should also motivate them to continue searching for cognitively demanding experiences after they have left the program.

Flynn in his 2007 book What Is Intelligence? further expanded on this theory. Environmental changes resulting from modernization — such as more intellectually demanding work, greater use of technology and smaller families — have meant that a much larger proportion of people are more accustomed to manipulating abstract concepts such as hypotheses and categories than a century ago. Substantial portions of IQ tests deal with these abilities. Flynn gives, as an example, the question 'What do a dog and a rabbit have in common?' A modern respondent might say they are both mammals (an abstract, or a priori answer, which depends only on the meanings of the words 'dog' and 'rabbit' ), whereas someone a century ago might have said that humans catch rabbits with dogs (a concrete, or a posteriori answer, which depended on what happened to be the case at that time).

Nutrition

Improved nutrition is another possible explanation. Today's average adult from an industrialized nation is taller than a comparable adult of a century ago. That increase of stature, likely the result of general improvements of nutrition and health, has been at a rate of more than a centimeter per decade. Available data suggest that these gains have been accompanied by analogous increases of head size, and by an increase in the average size of the brain. This argument had been thought to suffer the difficulty that groups who tend to be of smaller overall body size (e.g. women, or people of Asian ancestry) do not have lower average IQs. Richard Lynn, however, claims that while people of East Asian origin may often have smaller bodies, they tend to have larger brains and higher IQs than average whites.

A 2005 study presented data supporting the nutrition hypothesis, which predicts that gains will occur predominantly at the low end of the IQ distribution, where nutritional deprivation is probably most severe. An alternative interpretation of skewed IQ gains could be that improved education has been particularly important for this group. Richard Lynn makes the case for nutrition, arguing that cultural factors cannot typically explain the Flynn effect because its gains are observed even at infant and preschool levels, with rates of IQ test score increase about equal to those of school students and adults. Lynn states that "This rules out improvements in education, greater test sophistication, etc. and most of the other factors that have been proposed to explain the Flynn effect. He proposes that the most probable factor has been improvements in pre-natal and early post-natal nutrition."

A century ago, nutritional deficiencies may have limited body and organ functionality, including skull volume. The first two years of life is a critical time for nutrition. The consequences of malnutrition can be irreversible and may include poor cognitive development, educability, and future economic productivity. On the other hand, Flynn has pointed to 20-point gains on Dutch military (Raven's type) IQ tests between 1952, 1962, 1972, and 1982. He observes that the Dutch 18-year-olds of 1962 had a major nutritional handicap. They were either in the womb, or were recently born, during the great Dutch famine of 1944 – when German troops monopolized food and 18,000 people died of starvation. Yet, concludes Flynn, "they do not show up even as a blip in the pattern of Dutch IQ gains. It is as if the famine had never occurred." It appears that the effects of diet are gradual, taking effect over decades (affecting mother as well as child) rather than a few months.

In support of the nutritional hypothesis, it is known that, in the United States, the average height before 1900 was about 10 cm (∼4 inches) shorter than it is today. Possibly related to the Flynn effect is a similar change of skull size and shape during the last 150 years. Though the idea that brain size is unrelated to race and intelligence was popularized in the 1980s, studies continue to show significant correlations. A Norwegian study found that height gains were strongly correlated with intelligence gains until the cessation of height gains in military conscript cohorts towards the end of the 1980s. Both height and skull size increases probably result from a combination of phenotypic plasticity and genetic selection over this period. With only five or six human generations in 150 years, time for natural selection has been very limited, suggesting that increased skeletal size resulting from changes in population phenotypes is more likely than recent genetic evolution.

It is well known that micronutrient deficiencies change the development of intelligence. For instance, one study has found that iodine deficiency caused a fall, on average, of 12 IQ points in China.

Scientists James Feyrer, Dimitra Politi, and David N. Weil have found in the U.S. that the proliferation of iodized salt increased IQ by 15 points in some areas. Journalist Max Nisen has stated that, with this type of salt becoming popular, that "the aggregate effect has been extremely positive."

Daley et al. (2003) found a significant Flynn effect among children in rural Kenya, and concluded that nutrition was one of the hypothesized explanations that best explained their results (the others were parental literacy and family structure).

Infectious diseases

Eppig, Fincher, and Thornhill (2009) argue that "From an energetics standpoint, a developing human will have difficulty building a brain and fighting off infectious diseases at the same time, as both are very metabolically costly tasks" and that "the Flynn effect may be caused in part by the decrease in the intensity of infectious diseases as nations develop." They suggest that improvements in gross domestic product (GDP), education, literacy, and nutrition may have an effect on IQ mainly through reducing the intensity of infectious diseases.

Eppig, Fincher, and Thornhill (2011) in a similar study instead looking at different US states found that states with a higher prevalence of infectious diseases had lower average IQ. The effect remained after controlling for the effects of wealth and educational variation.

Atheendar Venkataramani (2010) studied the effect of malaria on IQ in a sample of Mexicans. Exposure during the birth year to malaria eradication was associated with increases in IQ. It also increased the probability of employment in a skilled occupation. The author suggests that this may be one explanation for the Flynn effect and that this may be an important explanation for the link between national malaria burden and economic development. A literature review of 44 papers states that cognitive abilities and school performance were shown to be impaired in sub-groups of patients (with either cerebral malaria or uncomplicated malaria) when compared with healthy controls. Studies comparing cognitive functions before and after treatment for acute malarial illness continued to show significantly impaired school performance and cognitive abilities even after recovery. Malaria prophylaxis was shown to improve cognitive function and school performance in clinical trials when compared to placebo groups.

Heterosis

Heterosis, or hybrid vigor associated with historical reductions of the levels of inbreeding, has been proposed by Michael Mingroni as an alternative explanation of the Flynn effect. However, James Flynn has pointed out that even if everyone mated with a sibling in 1900, subsequent increases in heterosis would not be a sufficient explanation of the observed IQ gains.

Possible end of progression

Jon Martin Sundet and colleagues (2004) examined scores on intelligence tests given to Norwegian conscripts between the 1950s and 2002. They found that the increase of scores of general intelligence stopped after the mid-1990s and declined in numerical reasoning sub-tests.

Teasdale and Owen (2005) examined the results of IQ tests given to Danish male conscripts. Between 1959 and 1979 the gains were 3 points per decade. Between 1979 and 1989 the increase approached 2 IQ points. Between 1989 and 1998 the gain was about 1.3 points. Between 1998 and 2004 IQ declined by about the same amount as it gained between 1989 and 1998. They speculate that "a contributing factor in this recent fall could be a simultaneous decline in proportions of students entering 3-year advanced-level school programs for 16–18-year-olds." The same authors in a more comprehensive 2008 study, again on Danish male conscripts, found that there was a 1.5-point increase between 1988 and 1998, but a 1.5-point decrease between 1998 and 2003/2004. A possible contributing factor to the more recent decline may be changes in the Danish educational system. Another may be the rising proportion of immigrants or their immediate descendants in Denmark. This is supported by data on Danish draftees where first or second generation immigrants with Danish nationality score below average.

In Australia, the IQ of 6–11 year olds as measured by the Colored Progressive Matrices has shown no increase from 1975–2003.

In the United Kingdom, a study by Flynn (2009) found that tests carried out in 1980 and again in 2008 show that the IQ score of an average 14-year-old dropped by more than two points over the period. For the upper half of the results the performance was even worse. Average IQ scores declined by six points. However, children aged between five and 10 saw their IQs increase by up to half a point a year over the three decades. Flynn argues that the abnormal drop in British teenage IQ could be due to youth culture having “stagnated” or even dumbed down. He also states that the youth culture is more oriented towards computer games than towards reading and holding conversations. Researcher Richard Gray, commenting on the study, also mentions the computer culture diminishing reading books as well as a tendency towards teaching to the test.

Lynn and Harvey argued in 2008 that the causes of the above are difficult to interpret since these countries had had significant recent immigration from countries with lower average national IQs. Nevertheless, they expect that similar patterns will occur, or have occurred, first in other developed nations and then in the developing world as there is a limit to how much environmental factors can improve intelligence. Furthermore, during the last century there is a negative correlation between fertility and intelligence although there is not yet any conclusive evidence of the association between the two. They estimate that there has been a dysgenic decline in the world's genotypic IQ (masked by the Flynn effect for the phenotype) of 0.86 IQ points per decade for the years 1950–2000.

Bratsberg & Rogeberg (2018) present evidence that the Flynn effect in Norway has reversed, and that both the original rise in mean IQ scores and their subsequent decline were caused by environmental factors.

IQ group differences

If the Flynn effect has ended in developed nations, then this may possibly allow national differences in IQ scores to diminish if the Flynn effect continues in nations with lower average national IQs.

Also, if the Flynn effect has ended for the majority in developed nations, it may still continue for minorities, especially for groups like immigrants where many may have received poor nutrition during early childhood or have had other disadvantages. A study in the Netherlands found that children of non-Western immigrants had improvements for g, educational achievements, and work proficiency compared to their parents, although there were still remaining differences compared to ethnic Dutch.

There is a controversy as to whether the US racial gap in IQ scores is diminishing. If that is the case then this may or may not be related to the Flynn effect. Flynn has commented that he never claimed that the Flynn effect has the same causes as the black-white gap, but that it shows that environmental factors can create IQ differences of a magnitude similar to the gap. Research that has examined whether g factor and IQ gains from the Flynn effect are related have found there is a negative correlation between the two, which may indicate that group differences and the Flynn effect are possibly due to differing causes.

The Flynn effect has also been part of the discussions regarding Spearman's hypothesis, which states that differences in the g factor are the major source of differences between blacks and whites observed in many studies of race and intelligence.
