The SAT is a standardized test widely used for college admissions in the United States. It was first introduced in 1926, and its name and scoring have changed several times, being originally called the Scholastic Aptitude Test, then the Scholastic Assessment Test, then the SAT Reasoning Test, and now simply the SAT.
The SAT is owned and published by the Educational Testing Service. The test is intended to assess a student's readiness for college. It is designed to not be aligned to high school curriculum.
The current SAT, introduced in 2005, takes 3 hours and 45 minutes to finish, and as of 2014 costs US$52.50 (up to US$101.5 outside of the United States), excluding late fees. Possible scores on the SAT range from 600 to 2400, combining test results from three 800-point sections: Mathematics, Critical Reading, and Writing. Taking the SAT or its competitor, the ACT, is required for freshman entry to many, but not all, universities in the United States.
On March 5, 2014, the College Board announced that a redesigned version of the SAT would be administered for the first time in 2016. The exam will revert to the 1600-point scale, the essay will be optional, and students will have 3 hours to take the exam plus 50 additional minutes to complete the essay.

The SAT is typically taken by high school sophomores, juniors and seniors. The College Board states that the SAT measures literacy and writing skills that are needed for academic success in college. They state that the SAT assesses how well the test takers analyze and solve problems—skills they learned in school that they will need in college. However, the test is administered under a tight time limit (speeded) to help produce a range of scores.
The College Board also states that use of the SAT in combination with high school grade point average (GPA) provides a better indicator of success in college than high school grades alone, as measured by college freshman GPA. Various studies conducted over the lifetime of the SAT show a statistically significant increase in correlation of high school grades and college freshman grades when the SAT is factored in. A large independent validity study on the SAT's ability to predict college freshman GPA was performed by the University of California. The results of this study found how well various predictor variables could explain the variance in college freshman GPA. It found that independently high school GPA could explain 15.4% of the variance in college freshman GPA, SAT I (the Math and Verbal SAT sections) could explain 13.3% of the variance in college freshman GPA, and SAT II (also known as SAT subject tests; in the UC's case specifically Writing, Mathematics IC or IIC, plus a third subject test of the student's choice) could explain 16% of the variance in college freshman GPA. When high school GPA and the SAT I were combined, they explained 20.8% of the variance in college freshman GPA. When high school GPA and the SAT II were combined, they explained 22.2% of the variance in college freshman GPA. When SAT I was added to the combination of high school GPA and SAT II, it added a .1% increase in explaining the variance in college freshman GPA for a total of 22.3%.
There are substantial differences in funding, curricula, grading, and difficulty among U.S. secondary schools due to U.S. federalism, local control, and the prevalence of private, distance, and home schooled students. SAT (and ACT) scores are intended to supplement the secondary school record and help admission officers put local data—such as course work, grades, and class rank—in a national perspective.
Historically, the SAT was more widely used by students living in coastal states and the ACT was more widely used by students in the Midwest and South; in recent years, however, an increasing number of students on the East and West coasts have been taking the ACT. Since 2007, all four-year colleges and universities in the United States that require a test as part of an application for admission will accept either the SAT or ACT, and hundreds of colleges and universities do not require any standardized test scores at all for admission.
SAT consists of three major sections: Critical Reading, Mathematics, and Writing. Each section receives a score on the scale of 200–800. All scores are multiples of 10. Total scores are calculated by adding up scores of the three sections. Each major section is divided into three parts. There are 10 sub-sections, including an additional 25-minute experimental or "equating" section that may be in any of the three major sections. The experimental section is used to normalize questions for future administrations of the SAT and does not count toward the final score. The test contains 3 hours and 45 minutes of actual timed sections; most administrations (after accounting for orientation, distribution of materials, completion of biographical sections, and fifteen minutes of timed breaks) run for about four and a half hours. The questions range from easy, medium, and hard depending on the scoring from the experimental sections. Easier questions typically appear closer to the beginning of the section while harder questions are toward the end in certain sections. This is not true for every section (the Critical Reading section is in chronological order) but it is the rule of thumb mainly for math, grammar, and the 19 sentence-completions in the reading sections.
The Critical Reading section of the SAT is made up of three scored sections: two 25-minute sections and one 20-minute section, with varying types of questions, including sentence completions and questions about short and long reading passages. Critical Reading sections normally begin with 5 to 8 sentence completion questions; the remainder of the questions are focused on the reading passages. Sentence completions generally test the student's vocabulary and understanding of sentence structure and organization by requiring the student to select one or two words that best complete a given sentence. The bulk of the Critical Reading section is made up of questions regarding reading passages, in which students read short excerpts on social sciences, humanities, physical sciences, or personal narratives and answer questions based on the passage. Certain sections contain passages asking the student to compare two related passages; generally, these consist of shorter reading passages. The number of questions about each passage is proportional to the length of the passage. Unlike in the Mathematics section, where questions go in the order of difficulty, questions in the Critical Reading section go in the order of the passage. Overall, question sets near the beginning of the section are easier, and question sets near the end of the section are harder.
The Mathematics section of the SAT is widely known as the Quantitative Section or Calculation Section. The mathematics section consists of three scored sections. There are two 25-minute sections and one 20-minute section, as follows:
- One of the 25-minute sections is entirely multiple choice.
- The other 25-minute section contains 8 multiple choice questions and 10 grid-in questions. For grid-in questions, test-takers write the answer inside a grid on the answer sheet. Unlike multiple choice questions, there is no penalty for incorrect answers on grid-in questions because the test-taker is not limited to a few possible choices.
- The 20-minute section is all multiple choice, with 16 questions.
- New topics include Algebra II and scatter plots. These recent changes have resulted in a shorter, more quantitative exam requiring higher level mathematics courses relative to the previous exam.
Four-function, scientific, graphing and Computer Algebra System (CAS) calculators are permitted on the SAT math section; however, calculators are not permitted on either of the other sections. Calculators with

This broke the once tight link between academic coursework and college admission, a break that remains to this day."

The SAT is sometimes given to students younger than 13 by organizations such as the Study of Mathematically Precocious Youth, Johns Hopkins Center for Talented Youth, Duke TIP, and other organizations who use the results to select, study and mentor students of exceptional ability.
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 of 1450 on tests taken before April 1995, and scores of at least 1520 on tests taken between April 1995 and February 2005.
Use by high-IQ societies
Perelman, along with the National Council of Teachers of English also criticized the 25-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. "You're getting teachers to train students to be bad writers", concluded Perelman.
In 2005, MIT Writing Director Les Perelman plotted essay length versus essay score on the new SAT from released essays and found a high correlation between them. After studying over 50 graded essays, he found that longer essays consistently produced higher scores. In fact, he argues that by simply gauging the length of an essay without reading it, the given score of an essay could likely be determined correctly over 90% of the time. He also discovered that several of these essays were full of factual errors; the College Board does not claim to grade for factual accuracy.
In the 1960s and 1970s 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.
In response to threats by the University of California to drop the SAT as an admission requirement, the College Entrance Examination Board announced the restructuring of the SAT, to take effect in March 2005, as detailed above.
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.
One example of a college that did this is Drew University in New Jersey. After they adopted an optional SAT policy, they had a 20% increase in applications. Dean of Admissions Mary Beth Carey says that "Our own research showed us that high school grade point average is by far the most important predictor of success in college." The college reported that they accepted their most diverse class ever as a result of the policy.
A growing number of colleges have joined the SAT optional movement. These colleges do not require the SAT for admission.
Montgomery and Lilly (2012) performed a systematic literature review of all published SAT coaching research in search of high quality studies (defined as those with randomized controlled trials). They found that the randomized treatments resulted in V/M gains of +23/32 points for a total of +56; the high quality study that showed the highest score increase was Johnson (1984; San Francisco) which was based on a 30-hour prep course that showed an average increase of 178 points. The Johnson San Francisco study was also the only high quality study found on a prep course of 30 hours or more in length, although validity of this outlier study is uncertain due to the attrition of half the participants.
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. Other studies have shown significantly different results. A longitudinal study from Ohio State showed that taking private SAT prep classes correlated with scores higher by ~60 points. A study from Oxford showed that coaching courses boosted scores by an average of 56 points. The founder of Ivy Bound Test Prep claimed in an interview that diligent students of their courses will see at least a 150-point increase.
The third and final major discrepancy is family income. Parents with a higher income can afford to spend money on their child’s education if they are not satisfied with it, while families with a lower income cannot. Families that have a higher family income can purchase multiple prep books, more specifically the College Board one. They can also pay for tutors, prep classes, and other resources such as The Princeton Review and Kaplan. These resources not only prepare the students for the knowledge required in the test, but also provide practice tests and sample problems that can be studied and possibly be seen on the real exam. Another source of this difference comes from the quality of schooling as family income increases. Those with higher income families, “tend to have better teachers, more resource-rich educational environments, more educated parents who can help them with school and, sometimes, expensive SAT tutoring.” The quality of education the student receives greatly affect the success during the test because the school not only relates to the student’s knowledge but also many times correlates with the students study habits and motivation to succeed. As with racial bias, this correlation with income could also be due to the social class of the makers of the test, although empirical research suggests that poorer students actually perform worse on 'neutral' than such 'privileged' questions.
The largest correlation 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.
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 commonly perceived 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.
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. Some studies have also shown that African American students under-perform in college relative to their white peers with the same SAT test scores; researchers have argued that this is likely because white students tend to benefit from social advantages outside of the educational environment (for example, high parental involvement in their education) which result in better grades.
One set of studies has reported differential item functioning - namely, some test questions function differently based on the racial group of the test taker, reflecting some kind of systematic difference in a groups ability to understand certain test questions or to acquire the knowledge required to answer them. In 2003 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.  The study was severely criticized by the ETS board, but the findings were replicated in a subsequent study by Santelices and Wilson in 2010.
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. Some researchers have also argued that since SAT scores correlate highly with IQ scores, which in turn they consider to be partially determined by innate biology, the SAT discrepancy can be explainable in part by biological differences between races. It has also been suggested that stereotype threat has a significant effect on lowering achievement of minority students. 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.
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.
Race and ethnicity
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. A famous (and long past) example of this bias in the SAT I was the oarsman–regatta analogy question. The object of the question was to find the pair of terms that had the relationship most similar to the relationship between "runner" and "marathon". 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. However, according to Murray and Herrnstein, the black-white gap is smaller in culture-loaded questions like this one than in questions that appear to be culturally neutral. Analogy questions have since been replaced by short reading passages.
Frey and Detterman (2003) investigated associations of SAT scores with intelligence test scores. Using an estimate of general mental ability, or g, based on the ASVAB test battery, which can be best thought of as representing crystallized intelligence (learned abilities), they found SAT scores to be highly correlated with g (r=.82 in their sample, .857 when adjusted for non-linearity) in their sample taken from a 1979 national probability survey. 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 found that the correlation of SAT results with scores on the Raven's Advanced Progressive Matrices was .483. They estimated that this latter correlation would have been about 0.72 were it not for the restriction of ability range in the sample. They also noted that there appeared to be a ceiling effect on the Raven’s scores which may have suppressed the correlation. Beaujean and colleagues (2006) have reached similar conclusions to those reached by Frey and Detterman.
Correlations with student traits
The College Board has been accused of completely reusing old SAT papers previously given in the United States.
Reuse of old SAT exams
In 2002, Richard Rothstein (education scholar and columnist) wrote in The New York Times that the U.S. math averages on the SAT and ACT continued its decade-long rise over national verbal averages on the tests.
Math–verbal achievement gap

On March 5, 2014, 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 new exam will be administered for the first time in spring 2016. Some of the major changes are: an emphasis on the use of evidence to support answers, a shift away from obscure vocabulary to words that students are more likely to encounter in college and career, a math section that is focused on fewer areas, a return to the 1600-point score scale, an optional essay, and the removal of penalty for wrong answers (rights-only scoring). To combat the perceived advantage of costly test preparation courses, the College Board announced a new partnership with Khan Academy to offer free online practice problems and instructional videos.
Beginning in 2012, test takers are required to submit a current, recognizable photo during registration. Students are required to present their photo admission ticket – or another acceptable form of photo ID – for admittance to their designated test center. Student scores and registration information, including the photo provided, are made available to the student’s high school. 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 they are all admitted students.
In late 2008, a new variable came into play. Previously, applicants to most colleges were required to submit all scores, with some colleges that embraced Score Choice retaining the option of allowing their applicants not to have to submit all scores. However, in 2008, an initiative to make Score Choice universal had begun, with some opposition from colleges desiring to maintain score report practices. While students theoretically now have the choice to submit their best score (in theory one could send any score one wishes to send) to the college of their choice, some popular colleges and universities, such as Cornell, ask that students send all test scores. This had led the College Board to display on their web site which colleges agree with or dislike Score Choice, with continued claims that students will still never have scores submitted against their will. Regardless of whether a given college permits applicants to exercise Score Choice options, most colleges do not penalize students who report poor scores along with high ones; many universities, such as Columbia and Cornell, expressly promise to overlook those scores that may be undesirable to the student and/or to focus more on those scores that are most representative of the student's achievement and academic potential. College Board maintains a list of colleges and their respective score choice policies that is recent as of November 2011.
In March 2006, it was announced that a small percentage of the SATs taken in October 2005 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 announced they would change the scores for the students who were given a lower score than they earned, but at this point many of those students had already applied to colleges using their original 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 2006 on behalf of the 4,411 students who received an incorrect score on the SAT. The class-action suit was settled in August 2007 when the College Board and Pearson Educational Measurement, the company that scored the SAT tests, announced they would pay $2.85 million into a settlement fund. Under the agreement each student could either elect to receive $275 or submit a claim for more money if he or she felt the damage was greater. A similar scoring error occurred on a secondary school admission test in 2010-2011 when the ERB (Educational Records Bureau) announced after the admission process was over that an error had been made in the scoring of the tests of 2010 (17%) of the students who had taken the Independent School Entrance Examination for admission to private secondary schools for 2011. Commenting on the effect of the error on students' school applications in the New York Times, David Clune, President of the ERB stated "It is a lesson we all learn at some point — that life isn’t fair."
Scoring problems of October 2005 tests
In 2005, the test was changed again, largely in response to criticism by the University of California system. Because of issues concerning ambiguous questions, especially analogies, certain types of questions were eliminated (the analogies from the verbal and quantitative comparisons from the Math section). The test was made marginally harder, as a corrective to the rising number of perfect scores. A new writing section, with an essay, based on the former SAT II Writing Subject Test, was added, in part to increase the chances of closing the opening gap between the highest and midrange scores. Other factors included the desire to test the writing ability of each student; hence the essay. The New SAT was first offered on March 12, 2005, after the last administration of the "old" SAT in January 2005. The Mathematics section was expanded to cover three years of high school mathematics. The Verbal section's name was changed to the Critical Reading section.
In October 2002, the College Board dropped the Score Choice Option for SAT-II exams. Under this option, scores were not released to colleges until the student saw and approved of the score. The College Board has since decided to re-implement Score Choice in the spring of 2009. It is described as optional, and it is not clear if the reports sent will indicate whether or not this student has opted-in or not. A number of highly selective colleges and universities, including Yale, the University of Pennsylvania, and Stanford, have announced they will require applicants to submit all scores. Stanford, however, only prohibits Score Choice for the traditional SAT. Others, such as MIT and Harvard, have fully embraced Score Choice.
2002 changes – Score Choice
Certain educational organizations viewed the SAT re-centering initiative as an attempt to stave off international embarrassment in regard to continuously declining test scores, even among top students. As evidence, it was presented that the number of pupils who scored above 600 on the verbal portion of the test had fallen from a peak of 112,530 in 1972 to 73,080 in 1993, a 36% backslide, despite (or perhaps because of) the fact that the total number of test-takers had risen over 500,000.
1995 re-centering controversy
Beginning with the test administered in April 1995, the SAT score scale was recentered to return the average math and verbal scores close to 500. Although only 25 students had received perfect scores of 1600 in all of 1994, 137 students taking the April test scored a 1600. The new scale used a reference group of about one million seniors in the class of 1990: the scale was designed so that the SAT scores of this cohort would have a mean of 500 and a standard deviation of 110. Because the new scale would not be directly comparable to the old scale, scores awarded on April 1995 and later were officially reported with an "R" (for example, "560R") to reflect the change in scale, a practice that was continued until 2001. Scores awarded before April 1995 may be compared to the those on the recentered scale by using official College Board tables. For example, verbal and math scores of 500 received before 1995 correspond to scores of 580 and 520, respectively, on the 1995 scale.
The drop in SAT verbal scores, in particular, meant that the usefulness of the SAT score scale (200 to 800) had become degraded. At the top end of the verbal scale, significant gaps were occurring between raw scores and uncorrected scaled scores: a perfect raw score no longer corresponded to an 800, and a single omission out of 85 questions could lead to a drop of 30 or 40 points in the scaled score. Corrections to scores above 700 had been necessary to reduce the size of the gaps and to make a perfect raw score result in an 800. At the other end of the scale, about 1.5 percent of test takers would have scored below 200 on the verbal section if that had not been the reported minimum score. Although the math score averages were closer to the center of the scale (500) than the verbal scores, the distribution of math scores was no longer well approximated by a normal distribution. These problems, among others, suggested that the original score scale and its reference group of about 10,000 students taking the SAT in 1941 needed to be replaced.
By the early 1990s, average total SAT scores were around 900 (typically, 425 on the verbal and 475 on the math). The average scores on the 1994 modification of the SAT I were similar: 428 on the verbal and 482 on the math. SAT scores for admitted applicants to highly selective colleges in the United States were typically much higher. For example, the score ranges of the middle 50% of admitted applicants to Princeton University in 1985 were 600 to 720 (verbal) and 660 to 750 (math). Similarly, median scores on the modified 1994 SAT for freshmen entering Yale University in the fall of 1995 were 670 (verbal) and 720 (math). For the majority of SAT test takers, however, verbal and math scores were below 500: In 1992, half of the college-bound seniors taking the SAT were scoring between 340 and 500 on the verbal section and between 380 and 560 on the math section, with corresponding median scores of 420 and 470, respectively.
1995 recentering (raising mean score back to 500)
Major changes were also made to the SAT mathematics section at this time, due in part to the influence of suggestions made by the National Council of Teachers of Mathematics. Test-takers were now permitted to use calculators on the math sections of the SAT. Also, for the first time since 1935, the SAT would now include some math questions that were not multiple choice, instead requiring students to supply the answers. Additionally, some of these "student-produced response" questions could have more than one correct answer. The tested mathematics content on the SAT was expanded to include concepts of slope of a line, probability, elementary statistics including median and mode, and counting problems.
In early 1994, substantial changes were made to the SAT. Antonyms were removed from the verbal section in order to make rote memorization of vocabulary less useful. Also, the fraction of verbal questions devoted to passage-based reading material was increased from about 30% to about 50%, and the passages were chosen to be more like typical college-level reading material, compared to previous SAT reading passages. The changes for increased emphasis on analytical reading were made in response to a 1990 report issued by a commission established by the College Board. The commission recommended that the SAT should, among other things, "approximate more closely the skills used in college and high school work". A mandatory essay had been considered as well for the new version of the SAT; however, criticism from minority groups as well as a concomitant increase in the cost of the test necessary to grade the essay led the College Board to drop it from the planned changes.
From 1926 to 1941, scores on the SAT were scaled to make 500 the mean score on each section. In 1941 and 1942, SAT scores were standardized via test equating, and as a consequence, average verbal and math scores could vary from that time forward. In 1952, mean verbal and math scores were 476 and 494, respectively, and scores were generally stable in the 1950s and early 1960s. However, starting in the mid-1960s and continuing until the early 1980s, SAT scores declined: the average verbal score dropped by about 50 points, and the average math score fell by about 30 points. By the late 1970s, only the upper third of test takers were doing as well as the upper half of those taking the SAT in 1963. From 1961 to 1977, the number of SAT tests taken per year doubled, suggesting that the decline could be explained by demographic changes in the group of students taking the SAT. Commissioned by the College Board, an independent study of the decline found that most (up to about 75%) of the test decline in the 1960s could be explained by compositional changes in the group of students taking the test; however, only about 25 percent of the 1970s decrease in test scores could similarly be explained. Later analyses suggested that up to 40 percent of the 1970s decline in scores could be explained by demographic changes, leaving unknown at least some of the reasons for the decline.
1960s and 1970s score declines
Paragraph reading was eliminated from the verbal portion of the SAT in 1946, and replaced with reading comprehension, and "double definition" questions were replaced with sentence completions. Between 1946 and 1957 students were given 90 to 100 minutes to complete 107 to 170 verbal questions. Starting in 1958 time limits became more stable, and for 17 years, until 1975, students had 75 minutes to answer 90 questions. In 1959 questions on data sufficiency were introduced to the mathematics section, and then replaced with quantitative comparisons in 1974. In 1974 both verbal and math sections were reduced from 75 minutes to 60 minutes each, with changes in test composition compensating for the decreased time.
1946 test and associated changes
In order to make cross-year score comparisons possible, in April 1941 the SAT verbal section was scaled to a mean of 500, and a standard deviation of 100, and the June 1941 SAT verbal section was equated (linked) to the April 1941 test. All SAT verbal sections after 1941 were equated to previous tests so that the same scores on different SAT tests would be comparable. Similarly, in June 1942 the SAT math section was equated to the April 1942 math section, which itself was linked to the 1942 SAT verbal section, and all SAT math sections after 1942 would be equated to previous tests. From this point forward, SAT mean scores could change over time, depending on the average ability of the group taking the test compared to the roughly 10,600 students taking the SAT in April 1941. The 1941 and 1942 score scales would remain in use until 1995.  
Until 1941, the scores on all SAT tests had been scaled to a mean of 500 with a standard deviation of 100. Although one test-taker could be compared to another for a given test date, comparisons from one year to another could not be made. For example, a score of 500 achieved on an SAT taken in one year could reflect a different ability level than a score of 500 achieved in another year. By 1940, it had become clear that setting the mean SAT score to 500 every year was unfair to those students who happened to take the SAT with a group of higher average ability.
1941 and 1942 score scales
In 1930 the SAT was first split into the verbal and math sections, a structure that would continue through 2004. The verbal section of the 1930 test covered a more narrow range of content than its predecessors, examining only antonyms, double definitions (somewhat similar to sentence completions), and paragraph reading. In 1936, analogies were re-added. Between 1936 and 1946, students had between 80 and 115 minutes to answer 250 verbal questions (over a third of which were on antonyms). The mathematics test introduced in 1930 contained 100 free response questions to be answered in 80 minutes, and focused primarily on speed. From 1936 to 1941, like the 1928 and 1929 tests, the mathematics section was eliminated entirely. When the mathematics portion of the test was re-added in 1942, it consisted of multiple choice questions.
1930 test and 1936 changes
In 1928 the number of verbal sections was reduced to 7, and the time limit was increased to slightly under two hours. In 1929 the number of sections was again reduced, this time to 6. These changes in part loosened time constraints on test-takers. Math was eliminated entirely for these tests, instead focusing only on verbal ability.
1928 and 1929 tests
The first administration of the SAT occurred on June 23, 1926, when it was known as the Scholastic Aptitude Test. This test, prepared by a committee headed by Princeton psychologist Carl Campbell Brigham, had sections of definitions, arithmetic, classification, artificial language, antonyms, number series, analogies, logical inference, and paragraph reading. It was administered to over 8,000 students at over 300 test centers. Men composed 60% of the test-takers. Slightly over a quarter of males and females applied to Yale University and Smith College. The test was paced rather quickly, test-takers being given only a little over 90 minutes to answer 315 questions.
On June 17, 1901, the first exams of the College Board were administered to 973 students across 67 locations in the United States, and two in Europe. Although those taking the test came from a variety of backgrounds, approximately one third were from New York, New Jersey, or Pennsylvania. The majority of those taking the test were from private schools, academies, or endowed schools. About 60% of those taking the test applied to Columbia University. The test contained sections on English, French, German, Latin, Greek, history, mathematics, chemistry, and physics. The test was not multiple choice, but instead was evaluated based on essay responses as "excellent", "good", "doubtful", "poor" or "very poor".
1901 essay exams
The SAT was a replacement for the individual tests that were used for each university. It was introduced during the Progressive Era and helped to give more students a chance to attend universities. Originally used mainly by colleges and universities in the northeastern United States, and developed by Carl Brigham, one of the psychologists who worked on the Army Alpha and Beta tests, the SAT was originally developed as a way to eliminate test bias between people from different socio-economic backgrounds.
The College Board and ACT, Inc. conducted a joint study of students who took both the SAT and the ACT between 2004 and 2006 and released a pair of concordance tables in 2009 that concord composite and writing scores separately. ACT, Inc. has also created its own "Estimated Relationship between ACT Composite Score and SAT CR+M+W Score" chart.
SAT-ACT score comparisons
In 2015 the average score for the Class of 2015 was 1490 out of a maximum 2400. That was down 7 points from the previous class’s mark and was the lowest composite score of the past decade.
The older SAT (before 1995) had a very high ceiling. In any given year, only seven of the million test-takers scored above 1580. A score above 1580 was equivalent to the 99.9995 percentile.
Score, 1600 Scale
Score, 2400 Scale
|* The percentile of the perfect score was 99.98 on the 2400 scale and 99.93 on the 1600 scale.|
|** 99+ means better than 99.5 percent of test takers.|
The percentiles that various SAT scores for college-bound seniors correspond to are summarized in the following chart:
The corresponding percentile of each scaled score varies from test to test—for example, in 2003, a scaled score of 800 in both sections of the SAT Reasoning Test corresponded to a percentile of 99.9, while a scaled score of 800 in the SAT Physics Test corresponded to the 94th percentile. The differences in what scores mean with regard to percentiles are due to the content of the exam and the caliber of students choosing to take each exam. Subject Tests are subject to intensive study (often in the form of an AP, which is relatively more difficult), and only those who know they will perform well tend to take these tests, creating a skewed distribution of scores.
Students receive their online score reports approximately three weeks after test administration (six weeks for mailed, paper scores), with each section graded on a scale of 200–800 and two sub scores for the writing section: the essay score and the multiple choice sub score. In addition to their score, students receive their percentile (the percentage of other test takers with lower scores). The raw score, or the number of points gained from correct answers and lost from incorrect answers is also included. Students may also receive, for an additional fee, the Question and Answer Service, which provides the student's answer, the correct answer to each question, and online resources explaining each question.
Raw scores, scaled scores, and percentiles
Students with verifiable disabilities, including physical and learning disabilities, are eligible to take the SAT with accommodations. The standard time increase for students requiring additional time due to learning disabilities is time + 50%; time + 100% is also offered.
Candidates whose religious beliefs prevent them from taking the test on a Saturday may request to take the test on the following day, except for the October test date in which the Sunday test date is eight days after the main test offering. Such requests must be made at the time of registration and are subject to denial.
The SAT costs $51 ($78 International, $99 for India and Pakistan, since the older testing system is in place). The College Board makes fee waivers available for low income students. Additional fees apply for late registration, standby testing, registration changes, scores by telephone, and extra score reports (beyond the four provided for free).
Candidates wishing to take the test may register online at the College Board's website, by mail, or by telephone, at least three weeks before the test date.
The SAT is offered seven times a year in the United States; in October, November, December, January, March (or April, alternating), May, and June. The test is typically offered on the first Saturday of the month for the November, December, May, and June administrations. In other countries, the SAT is offered on the same dates as in the United States except for the first spring test date (i.e., March or April), which is not offered. The test was taken by 1,672,395 high school graduates in the class of 2014.
|Section||Average Score||Time (Minutes)||Content|
|Writing||487||60||Grammar, usage, and diction.|
|Mathematics||513||70||Number and operations; algebra and functions; geometry; statistics, probability, and data analysis|
|Critical Reading||497||70||Vocabulary, Critical reading, and sentence-level reading|
The SAT therefore recommends only making educated guesses, that is, when the test taker can eliminate at least one answer he or she thinks is wrong. Without eliminating any answers one's probability of answering correctly is 20%. Eliminating one wrong answer increases this probability to 25% (and the expected gain to 1/16 of a point); two, a 33.3% probability (1/6 of a point); and three, a 50% probability (3/8 of a point).
The questions are weighted equally. For each correct answer, one raw point is added. For each incorrect answer one quarter of a point is deducted. No points are deducted for incorrect math grid-in questions. This ensures that a student's mathematically expected gain from guessing is zero. The final score is derived from the raw score; the precise conversion chart varies between test administrations.
Most of the questions on the SAT, except for the essay and the grid-in math responses, are multiple choice; all multiple-choice questions have five answer choices, one of which is correct. The questions of each section of the same type are generally ordered by difficulty. However, an important exception exists: Questions that follow the long and short reading passages are organized chronologically, rather than by difficulty. Ten of the questions in one of the math sub-sections are not multiple choice. They instead require the test taker to bubble in a number in a four-column grid.
Style of questions
In March 2005, Les Perelman analyzed 15 scored sample essays contained in the College Board's ScoreWrite book along with 30 other training samples and found that in over 90% of cases, the essay's score could be predicted from simply counting the number of words in the essay. Two years later, Perelman trained high school seniors to write essays that made little sense but contained infrequently used words such as "plethora" and "myriad". All of the students received scores of "10" or better, which placed the essays in the 92nd percentile or higher.
The essay section, which is always administered as the first section of the test, is 25 minutes long. All essays must be in response to a given prompt. The prompts are broad and often philosophical and are designed to be accessible to students regardless of their educational and social backgrounds. For instance, test takers may be asked to expand on such ideas as their opinion on the value of work in human life or whether technological change also carries negative consequences to those who benefit from it. No particular essay structure is required, and the College Board accepts examples "taken from [the student's] reading, studies, experience, or observations." Two trained readers assign each essay a score between 1 and 6, where a score of 0 is reserved for essays that are blank, off-topic, non-English, not written with a Number 2 pencil, or considered illegible after several attempts at reading. The scores are summed to produce a final score from 2 to 12 (or 0). If the two readers' scores differ by more than one point, then a senior third reader decides. The average time each reader/grader spends on each essay is less than 3 minutes.
The multiple choice questions include error-identification questions, sentence-improvement questions, and paragraph-improvement questions. Error-identification and sentence-improvement questions test the student's knowledge of grammar, presenting an awkward or grammatically incorrect sentence; in the error identification section, the student must locate the word producing the source of the error or indicate that the sentence has no error, while the sentence improvement section requires the student to select an acceptable fix to the awkward sentence. The paragraph improvement questions test the student's understanding of logical organization of ideas, presenting a poorly written student essay and asking a series of questions as to what changes might be made to best improve it.
The writing portion of the SAT, based on but not directly comparable to the old SAT II subject test in writing (which in turn was developed from the old Test of Standard Written English (TSWE)), includes multiple choice questions and a brief essay. The essay subscore contributes about 28% to the total writing score, with the multiple choice questions contributing 70%. This section was implemented in March 2005 following complaints from colleges about the lack of uniform examples of a student's writing ability and critical thinking.
The use of a Computer Algebra System calculator is sometimes preferred, especially for geometry problems and exercises involving multiple calculations. According to research conducted by the CollegeBoard, performance on the math sections of the exam is associated with the extent of calculator use, with those using calculators on about a third to a half of the items averaging higher scores than those using calculators less frequently. The use of a CAS calculator in mathematics courses, and also becoming familiar with the calculator outside of the classroom, is known to have a positive effect on the performance of students using a graphing calculator during the exam.
With the recent changes to the content of the SAT math section, the need to save time while maintaining accuracy of calculations has led some to use calculator programs during the test. These programs allow students to complete problems faster than would normally be possible when making calculations manually.
