The mathematics section was expanded to cover three years of high school mathematics. To emphasize the importance of reading, the verbal section's name was changed to the Critical Reading section.
In March , it was announced that a small percentage of the SATs taken in October had been scored incorrectly due to the test papers' being moist and not scanning properly and that some students had received erroneous scores.
The College Board decided not to change the scores for the students who were given a higher score than they earned. A lawsuit was filed in on behalf of the 4, students who received an incorrect score on the SAT.
At the time, some college admissions officials agreed that the new policy would help to alleviate student test anxiety, while others questioned whether the change was primarily an attempt to make the SAT more competitive with the ACT, which had long had a comparable score choice policy.
Since then, Cornell,  University of Pennsylvania,  and Stanford  have all adopted Score Choice, but Yale  continues to require applicants to submit all scores.
Others, such as MIT and Harvard , allow students to choose which scores they submit, and use only the highest score from each section when making admission decisions.
Still others, such as Oregon State University and University of Iowa , allow students to choose which scores they submit, considering only the test date with the highest combined score when making admission decisions.
Beginning in the fall of , test takers were required to submit a current, recognizable photo during registration. In order to be admitted to their designated test center, students were required to present their photo admission ticket—or another acceptable form of photo ID—for comparison to the one submitted by the student at the time of registration.
The changes were made in response to a series of cheating incidents, primarily at high schools in Long Island, New York, in which high-scoring test takers were using fake photo IDs to take the SAT for other students.
In the event of an investigation involving the validity of a student's test scores, their photo may be made available to institutions to which they have sent scores.
Any college that is granted access to a student's photo is first required to certify that the student has been admitted to the college requesting the photo.
On March 5, , the College Board announced its plan to redesign the SAT in order to link the exam more closely to the work high school students encounter in the classroom.
The SAT has been renamed several times since its introduction in It was originally known as the Scholastic Aptitude Test.
According to the president of the College Board at the time, the name change was meant "to correct the impression among some people that the SAT measures something that is innate and impervious to change regardless of effort or instruction.
Test preparation companies in Asia have been found to provide test questions to students within hours of a new SAT exam's administration.
The leaked PDF file was on the internet before the August 25, exam. This predictive validity was found to hold across demographic groups. For decades many critics have accused designers of the verbal SAT of cultural bias as an explanation for the disparity in scores between poorer and wealthier test-takers.
The correct answer was "oarsman" and "regatta". The choice of the correct answer was thought to have presupposed students' familiarity with rowing , a sport popular with the wealthy.
Analogy questions were removed in The largest association with gender on the SAT is found in the math section, where male students, on average, score higher than female students by approximately 30 points.
Some researchers believe that the difference in scores for both race and gender is closely related to the psychological phenomenon known as stereotype threat.
Stereotype threat is thought to occur when an individual who identifies themselves within a subgroup of people encounters a stereotype regarding their subgroup within the content of a test they are taking.
Some researchers believe that stereotype threat may be responsible for the underperformance of about 20 points on the math portion for women.
Other researchers question these assertions, and point to evidence in support of greater male variability in spatial ability and mathematics. Greater male variability has been found in body weight, height, and cognitive abilities across cultures, leading to a larger number of males in the lowest and highest distributions of testing   [ circular reference ].
This results in a higher number of males scoring in the upper extremes of mathematics tests such as the SAT, resulting in the gender discrepancy.
Although aspects of testing such as stereotype are a concern, research on the predictive validity of the SAT has demonstrated that it tends to be a more accurate predictor of female GPA in university as compared to male GPA.
African American, Hispanic, and Native American students, on average, perform an order of one standard deviation lower on the SAT than white and Asian students.
Researchers believe that the difference in scores is closely related to the overall achievement gap in American society between students of different racial groups.
This gap may be explainable in part by the fact that students of disadvantaged racial groups tend to go to schools that provide lower educational quality.
This view is supported by evidence that the black-white gap is higher in cities and neighborhoods that are more racially segregated.
For example, African Americans perform worse on a test when they are told that the test measures "verbal reasoning ability", than when no mention of the test subject is made.
John Ogbu , a Nigerian-American professor of anthropology, concluded that instead of looking to their parents as role models, black youth chose other models like rappers and did not make an effort to be good students.
One set of studies has reported differential item functioning, namely, that some test questions function differently based on the racial group of the test taker, reflecting differences in ability to understand certain test questions or to acquire the knowledge required to answer them between groups.
In , Freedle published data showing that Black students have had a slight advantage on the verbal questions that are labeled as difficult on the SAT, whereas white and Asian students tended to have a slight advantage on questions labeled as easy.
Freedle argued that these findings suggest that "easy" test items use vocabulary that is easier to understand for white middle class students than for minorities, who often use a different language in the home environment, whereas the difficult items use complex language learned only through lectures and textbooks, giving both student groups equal opportunities to acquiring it.
There is no evidence that SAT scores systematically underestimate future performance of minority students. However, the predictive validity of the SAT has been shown to depend on the dominant ethnic and racial composition of the college.
Christopher Jencks concludes that as a group, African Americans have been harmed by the introduction of standardized entrance exams such as the SAT. This, according to him, is not because the tests themselves are flawed, but because of labeling bias and selection bias; the tests measure the skills that African Americans are less likely to develop in their socialization, rather than the skills they are more likely to develop.
Furthermore, standardized entrance exams are often labeled as tests of general ability, rather than of certain aspects of ability.
Thus, a situation is produced in which African American ability is consistently underestimated within the education and workplace environments, contributing in turn to selection bias against them which exacerbates underachievement.
In the s and s there was a movement to drop achievement scores. After a period of time, the countries, states and provinces that reintroduced them agreed that academic standards had dropped, students had studied less, and had taken their studying less seriously.
They reintroduced the tests after studies and research concluded that the high-stakes tests produced benefits that outweighed the costs.
Atkinson , the president of the University of California , urged dropping the SAT as a college admissions requirement:.
Anyone involved in education should be concerned about how overemphasis on the SAT is distorting educational priorities and practices, how the test is perceived by many as unfair, and how it can have a devastating impact on the self-esteem and aspirations of young students.
There is widespread agreement that overemphasis on the SAT harms American education. Even now, no firm conclusions can be reached regarding the SAT's usefulness in the admissions process.
It may or may not be biased, and it may or may not serve as a check on grade inflation in secondary schools. Frey and Detterman investigated associations of SAT scores with intelligence test scores.
Additionally, they investigated the correlation between SAT results, using the revised and recentered form of the test, and scores on the Raven's Advanced Progressive Matrices , a test of fluid intelligence reasoning , this time using a non-random sample.
They also noted that there appeared to be a ceiling effect on the Raven's scores which may have suppressed the correlation. SAT preparation is a highly lucrative field.
The College Board maintains that the SAT is essentially uncoachable and research by the College Board and the National Association of College Admission Counseling suggests that tutoring courses result in an average increase of about 20 points on the math section and 10 points on the verbal section.
A meta-analysis estimated the effect size to be 0. Certain high IQ societies , like Mensa , the Prometheus Society and the Triple Nine Society , use scores from certain years as one of their admission tests.
For instance, the Triple Nine Society accepts scores verbal and math combined of or greater on SAT tests taken before April , and scores of at least on tests taken between April and February After studying over 50 graded essays, he found that longer essays consistently produced higher scores.
He also discovered that several of these essays were full of factual errors; the College Board does not claim to grade for factual accuracy.
Perelman, along with the National Council of Teachers of English, also criticized the minute writing section of the test for damaging standards of writing teaching in the classroom.
They say that writing teachers training their students for the SAT will not focus on revision, depth, accuracy, but will instead produce long, formulaic, and wordy pieces.
