The Law School Admission Test (LSAT) is a half-day standardized test administered four times each year at designated testing centers throughout the world. Administered by the Law School Admission Council (LSAC) for prospective law school candidates, the LSAT is designed to assess reading comprehension, logical, and verbal reasoning proficiencies.[7] The test is an integral part of the law school admission process in the United States, Canada (common law programs only), the University of Melbourne, Australia,[8][9] and a growing number of other countries. An applicant cannot take the LSAT more than three times within a two-year period.

The test has existed in some form since 1948, when it was created to give law schools a standardized way to assess applicants aside from GPA.[10] The current form of the exam has been used since 1991. The exam has six total sections: four scored multiple choice sections, an unscored experimental section, and an unscored writing section. Raw scores are converted to a scaled score with a high of 180, a low of 120, and a median score around 150. When an applicant applies to a law school, all scores from the past five years are reported. As of June 2014, it costs $170 (USD) to take the LSAT in the United States, and $165 (CAD) in Canada.[11]

The LSAT was the result of a 1945 inquiry of Frank Bowles, a Columbia Law School admissions director, about a more satisfactory admissions test that could be used for admissions than the one that was in use in 1945.[12] The goal was to find a test that would correlate with first year grades rather than bar passage rates. This led to an invitation of representatives from Harvard Law School and Yale Law School who ultimately accepted the invitation and began to draft the first administration of the LSAT exam. NYU, in correspondence by memorandum, was openly unconvinced "about the usefulness of an aptitude test as a method of selecting law school students", but was open to experimenting with the idea, as were other schools that were unconvinced. At a meeting on November 10, 1947, with representatives of law schools extending beyond the original Columbia, Harvard, and Yale representatives, the design of the LSAT was discussed. Interestingly, at this meeting the issue of a way to test students who came from excessively "technical" backgrounds that were deficient in the study of history and literature was discussed but ultimately rejected. The first administration of the LSAT followed and occurred in 1948.


LSAC administers the LSAT four times per year: June, September/October, December, and February. The June examination marks the start of a new "cycle" of testing as most test-takers plan to apply for admission the following year. The September/October administration is typically the most popular with the February administration being the least popular.

129,925 LSATs were administered in the 2011–12 testing year (June 2011–February 2012), the largest percentage decline in LSATs administered in more than 10 years, and a drop of more than 16% from the previous year, when 155,050 LSATs were administered. The number of LSATs administered fell more than 25% over a two-year period (from the 2009–10 testing year to the 2011–12 testing year).[13] The October 2012 administration reflected a 16.4% drop in volume from its 2011 counterpart. LSAT numbers continued to drop over the next two cycles but to a lesser degree, with 13.4% and 6.2% drops, respectively, for the 2012–13 and 2013–14 cycles. February 2014 showed the first increase in test takers (1.1%) since June 2010.[14]

Test composition

The LSAT consists of five 35-minute multiple choice sections (one of which is an unscored experimental section) followed by an unscored writing sample section. Modern tests have 99–102 scored items in total. Several different test forms are used within an administration, each presenting the multiple choice sections in different orders, which is intended to make it difficult to cheat or to guess which is the experimental section.

Logical reasoning

The LSAT contains two logical reasoning ("LR") sections, commonly known as "arguments", designed to test the taker's ability to dissect and analyze arguments. LR sections each contain 24–26 questions.[15] Each question begins with a short argument or set of facts. This is followed by a prompt asking the test taker to find the argument's assumption, to select an alternate conclusion to the argument, to identify errors or logical omissions in the argument, to find another argument with parallel reasoning, or to choose a statement that would weaken/strengthen the argument. Passages are currently followed by a single prompt, though in older tests (pre-2007), a few questions were followed by two prompts.

Reading comprehension

The LSAT contains one reading comprehension ("RC") section consisting of four passages of 400–500 words, and 5–8 questions relating to each passage. Complete sections contain 26–28 questions. Though no real rules govern the content of this section, the passages generally relate to law, arts and humanities, physical sciences, or social sciences. The questions usually ask the examinee to determine the author's main idea, find specific information in the passage, draw inferences from the text, and/or describe the structure of the passage.

In June 2007, one of the four passages was replaced with a "comparative reading" question.[16] Comparative reading presents two shorter passages with differing perspectives on a topic. Parallels exist between the comparative reading question, the SAT's critical reading section, and the science section of the ACT.

Analytical reasoning

The current LSAT contains one analytical reasoning section, which is referred to colloquially as the "logic games (LG)" section. One section contains four "games" falling into a number of categories including grouping, matching, and ordering of elements. Each LG section has 22–24 questions. Each game begins by outlining the premise ("there are five people who might attend this afternoon's meeting") and establishing a set of conditions governing the relationships among the subjects ("if Amy is present, then Bob is not present; if Cathy is present, then Dan is present..."). The examinee is then asked to draw conclusions from the statements ("What is the maximum number of people who could be present?"). What makes the games challenging is that the rules do not produce a single "correct" set of relationships among all elements of the game; rather, the examinee is tested on their ability to analyze the range of possibilities embedded in a set of rules. Individual questions often add rules or modify existing rules, requiring quick reorganization of known information. The analytical reasoning section is commonly regarded by LSAT takers as the most difficult section of the test, as well as the section that requires the most pre-test preparation.

Unscored Variable section

The current test contains one experimental section which Law Services refers to as the "Variable section". It is used to test new questions for future exams. The performance of the examinee on this section is not reported as part of the final score. The examinee is not told which section of the exam is experimental, since doing so could skew the data. Previously, this section has always been one of the first three sections of any given test, but beginning with the administration of the October 2011 LSAT the experimental can be after the first three sections.[17] LSAC makes no specific claim as to what section(s) it has appeared as in the past, and what section(s) it may appear as in the future.

Writing sample

The writing sample appears as the final section of the exam. The writing sample is presented in the form of a decision prompt, which provides the examinee with a problem and two criteria for making a decision. The examinee must then write an essay favoring one of the two options over the other. The decision prompt generally does not involve a controversial subject, but rather something mundane about which the examinee likely has no strong bias. While there is no "right" or "wrong" answer to the writing prompt, it is important that the examinee argues for his/her chosen position and also argues against the counter-position.

LSAC does not score the writing sample. Instead, the essay is digitally imaged and sent to admission offices along with the LSAT score. Between the quality of the handwriting and of the digital image, some admissions officers regard the readability and usefulness of the writing sample to be marginal. Additionally, most schools require that applicants submit a "personal statement" of some kind. These factors sometimes result in admission boards disregarding the writing sample. However, only 6.8% of 157 schools surveyed by LSAC in 2006 indicated that they "never" use the writing sample when evaluating an application. In contrast, 9.9% of the schools reported that they "always" use the sample; 25.3% reported that they "frequently" use the sample; 32.7% responded "occasionally"; and 25.3% reported "seldom" using the sample.[18]


LSAC recommends advance preparation for the LSAT, due to the importance of the LSAT in law school admissions and because scores on the exam typically correspond to preparation time.[19] The structure of the LSAT and the types of questions asked are generally consistent from year to year, which allows students to practice on question types that show up frequently in examinations.

LSAC suggests, at a minimum, that students review official practice tests, called PrepTests, before test day to familiarize themselves with the types of questions that appear on the exams.[20] LSAC offers one free test that can be downloaded from their website.[21] For best results, LSAC suggests taking practice tests under actual time constraints and representative conditions in order to identify problem areas to focus on in further review.[20]

For preparation purposes, only tests after June 1991 are considered modern, since the LSAT was significantly modified after this date. Each released exam is commonly referred to as a PrepTest. The June 1991 LSAT was numbered as PrepTest 1, and the December 2013 LSAT was PrepTest 71.[22] Certain PrepTests are no longer published by LSAC (among them 1–6, 8, 17, 39, and 40), despite the fact that they were in print at one time. However, these tests have been made available through some of the test preparation companies, which have licensed them from LSAC.

Some students taking the LSAT use a test preparation company. Students who do not use these courses often rely on material from LSAT preparation books, previously administered exams, and free web resources such as blogs and forums.


The LSAT is a standardized test in that LSAC adjusts raw scores to fit an expected norm to overcome the likelihood that some administrations may be more difficult than others. Normalized scores are distributed on a scale with a low of 120 to a high of 180.[23]

The LSAT system of scoring is predetermined and does not reflect test takers' percentile, unlike the SAT. The relationship between raw questions answered correctly (the "raw score") and scaled score is determined before the test is administered, through a process called equating.[24] This means that the conversion standard is set beforehand, and the distribution of percentiles can vary during the scoring of any particular LSAT.

Adjusted scores lie in a bell curve, tapering off at the extremes and concentrating near the median. For example, there might be a 3–5 question difference between a score of 175 and a score of 180, but the difference between a 155 from a 160 could be 9 or more questions. Although the exact percentile of a given score will vary slightly between examinations, there tends to be little variance. The 50th percentile is typically a score of about 151; the 90th percentile is around 165 and the 99th is about 173. A 178 or better usually places the examinee in the 99.9th percentile.

Examinees have the option of canceling their scores within six calendar days after the exam, before they get their scores. LSAC still reports to law schools that the student registered for and took the exam, but releases no score. Test takers typically receive their scores by e-mail between three and four weeks after the exam.[25] There is a formal appeals process for examinee complaints,[26] which has been used for proctor misconduct, peer misconduct, and occasionally for challenging a question. In very rare instances, specific questions have been omitted from final scoring.

University of North Texas economist Michael Nieswiadomy has conducted several studies (in 1998, 2006, and 2008) derived from LSAC data. In the most recent study Nieswiadomy took the LSAC's categorization of test-takers into 162 majors and grouped these into 29 categories, finding the averages of each major:[27]

Use of scores in law school admissions

The LSAT is considered an important part of the law school admissions process, along with GPA. Many law schools are selective in their decisions to admit students, and the LSAT is one method of differentiating candidates.

Additionally the LSAC says the LSAT (like the University Of Michigan have added programs designed to waive the LSAT for selected students who have maintained a 3.8 undergraduate GPA at their schools.[28]

LSAC says its own research supports the use of the LSAT as a major factor in admissions, saying the median validity for LSAT alone is .41 (2001) and .40 (2002) in regards to the first year of law school.[29] The correlation varies from school to school, and LSAC says that test scores are strongly correlated to first year law school performance than undergraduate GPA.[30] LSAC says that a more strongly correlated single-factor measure does not currently exist, that GPA is difficult to use because it is influenced by the school and the courses taken by the student, and that the LSAT can serve as a yardstick of student ability because it is statistically normed. In 2011 it was reported that the American Bar Association was considering a recommendation to end the requirement for law schools to use the LSAT as an admission requirement, as emphasis on LSAT scores is considered by some to be detrimental to the promotion of diversity among applicants.[31]

Most admission boards use an admission index, which is a formula that applies different weight to the LSAT and undergraduate GPA and adds the results. This composite statistic can have a stronger correlation to first year performance than either GPA or LSAT score alone, depending on the weighting used. The amount of weight assigned to LSAT score versus undergraduate GPA varies from school to school, as almost all law programs employ a different admission index formula.

Multiple scores

Students may take the test only three times in a two-year period unless they are granted an exemption from LSAC.[32] Every score within five years is reported to law schools during the application process, as well a separate average of all scores on record.[33] For admission determination, many law schools use the highest score on record, some use the average score, and some use the highest score if the difference between the highest and lowest score is at or greater than a certain number.[34]

How the law schools report the LSAT scores of their matriculants to the American Bar Association (ABA) has changed over the years. In June 2006, the ABA revised a rule that mandated law schools to report their matriculants' average score if more than one test was taken. The current ABA rule now requires law schools to report only the highest LSAT score for matriculants who took the test more than once. In response, many law schools began considering only the highest LSAT score during the admissions process, as the highest score is an important factor in law school rankings such as those published by US News and World Report.[35]

Fingerprinting controversy

Starting October 1973, those taking the LSAT were required to have fingerprints taken, after some examinees were found to have hired impostors to take the test on their behalf.[36]

A recent controversy surrounding the LSAT was the requirement that examinees submit to fingerprinting on the day of testing. Although LSAC does not store digital representations of fingerprints, there is a concern that fingerprints might be accessible by the U.S. Department of Homeland Security.[37] At the behest of the Privacy Commissioner of Canada, the LSAC implemented a change as of September 2007 which exempts Canadian test takers from the requirement to provide a fingerprint and instead requires that Canadian test-takers provide a photograph.[38] Starting with the June 2011 admission of the LSAT, LSAC expanded this policy to include test-takers in the United States and Caribbean; LSAC therefore no longer requires fingerprints from any test takers, and instead requires that they submit a photograph.[39]
