The LSAT (Law School Admission Test) is the standardized exam required for admission to virtually every ABA-accredited law school in the United States and Canada. Scored on a 120–180 scale, the LSAT measures your reading comprehension, logical reasoning, and analytical skills — not memorized legal knowledge. Whether you are a college sophomore exploring law school or a senior ready to register, this guide breaks down exactly what the LSAT tests, how it is structured, and what you need to know to start preparing.
The Law School Admission Test — commonly called the LSAT — is a standardized exam administered by the Law School Admission Council (LSAC). Unlike tests that quiz you on specific subjects, the LSAT is a skills-based exam designed to evaluate the reading, reasoning, and analytical abilities that are essential for succeeding in law school. You will not be tested on legal knowledge, case law, or any particular academic subject.
The LSAT is the only admissions test accepted by every ABA-accredited law school in the United States and Canada. That makes it a non-negotiable step for the vast majority of aspiring lawyers. With the 2025–2026 admissions cycle seeing an 18% increase in applicants — the highest volume in over a decade — a strong LSAT score has never been more important for standing out in a competitive applicant pool.
Research conducted by LSAC has consistently shown that the LSAT is the single best predictor of first-year law school performance — outperforming even undergraduate GPA. Law schools use your LSAT score alongside your GPA and personal statement to assess your readiness for the rigors of legal education. Admissions committees view the LSAT as a standardized baseline that allows them to compare applicants from different colleges, majors, and grading systems on a level playing field.
The LSAT format consists of four 35-minute multiple-choice sections plus a separately administered writing task. Three of the four multiple-choice sections are scored; the fourth is an unscored experimental section used by LSAC to test new questions.
| Section | Questions | Time | Scored |
|---|---|---|---|
| Logical Reasoning I | 24–26 | 35 minutes | Yes |
| Logical Reasoning II | 24–26 | 35 minutes | Yes |
| Reading Comprehension | 26–28 | 35 minutes | Yes |
| Experimental (Unscored) | Varies | 35 minutes | No |
| Argumentative Writing | 1 essay | 50 minutes | Sent to schools |
Logical Reasoning makes up two of the three scored sections, meaning it accounts for roughly half of your LSAT score. Each section contains 24–26 questions that ask you to analyze arguments, identify flaws in reasoning, strengthen or weaken conclusions, and draw logical inferences. These questions mirror the kind of critical thinking you will do daily in law school when reading cases and constructing legal arguments.
The Reading Comprehension section presents four passages (including one comparative reading set with two shorter passages) followed by 26–28 questions total. Passages cover topics from law, humanities, sciences, and social sciences. You will need to identify main ideas, understand the author's reasoning, and make inferences based on the text. Strong active reading skills — the ability to quickly grasp structure and argument — are essential here.
One of your four multiple-choice sections will be an unscored experimental section. LSAC uses this section to field-test new questions for future exams. The catch: you will not know which section is experimental during the test. Treat every section as if it counts, because it might.
The Argumentative Writing section is administered separately online, not on test day itself. You have 50 minutes to write an essay arguing for one of two positions on a given topic. While this section is not scored numerically, law schools receive a copy of your essay along with your score report. It demonstrates your ability to construct a clear, organized argument under time pressure — a skill law schools value.
Your LSAT score is calculated in two steps. First, your raw score is determined by the total number of correct answers across the three scored sections (approximately 75–76 questions). There is no penalty for wrong answers, so guessing is always better than leaving a question blank. Your raw score is then converted to a scaled score between 120 and 180 through a statistical process called equating, which ensures that scores from different test administrations are directly comparable.
The majority of LSAT test takers score between 145 and 160. Understanding where your score falls relative to other test takers helps you set realistic law school targets. The table below shows approximate percentile ranges and what they mean for admissions competitiveness.
| Score Range | Approximate Percentile | Competitiveness |
|---|---|---|
| 170–180 | 97th–99th | Top-14 law schools (T14) |
| 165–169 | 90th–96th | Top-25 law schools |
| 160–164 | 80th–89th | Competitive at most schools |
| 155–159 | 60th–79th | Many regional law schools |
| 150–154 | 40th–59th | Some accredited programs |
| 145–149 | 25th–39th | Limited options |
| 120–144 | Below 25th | Below average range |
If you are applying to an ABA-accredited law school in the United States or Canada, you almost certainly need an LSAT score. The LSAT is also accepted by a growing number of international law programs. There is no minimum educational requirement to sit for the LSAT — you do not need to have completed your undergraduate degree — but virtually all law schools require a bachelor's degree for admission.
A growing number of law schools now accept the GRE (Graduate Record Examination) as an alternative to the LSAT. Schools like Harvard, Columbia, and Cornell are among those that accept GRE scores. However, the LSAT remains the only test accepted by all ABA-accredited programs. If you are applying broadly, the LSAT is the safer choice. If you are targeting specific GRE-accepting schools and are already prepared for the GRE from other graduate program applications, it may be worth considering.
| Feature | LSAT | GRE |
|---|---|---|
| Accepted by | All ABA-accredited law schools | Some law schools (growing list) |
| Score range | 120–180 | 260–340 (two sections) |
| Test sections | Logical Reasoning, Reading Comprehension | Verbal, Quantitative, Analytical Writing |
| Test length | ~3 hours + writing | ~3 hours 45 minutes |
| Cost | $248 | $220 |
| Skills tested | Legal reasoning and reading | General academic readiness |
| Best for | Students committed to law school | Students considering multiple graduate paths |
Most LSAT prep experts recommend studying for three to four months, dedicating 10–12 hours per week, for a total of approximately 120 or more hours of preparation. Start by taking a free diagnostic test through LawHub (LSAC's official platform) to identify your baseline score and pinpoint your strengths and weaknesses. This initial assessment helps you build a focused study plan rather than spending time on areas where you already perform well.
The key to LSAT improvement is consistent, deliberate practice — not last-minute cramming. The LSAT tests reasoning patterns that develop over time through repeated exposure and analysis. Students who study regularly over several months consistently outperform those who try to compress their preparation into a few weeks.
Estimate how many hours you need to study based on your starting score and target score.
There is no one right way to prepare for the LSAT. Self-directed learners can access free official practice tests through LawHub and supplement with Khan Academy's LSAT prep materials. For those who prefer structured guidance, commercial prep courses from companies like Kaplan, Blueprint, 7Sage, and Princeton Review offer comprehensive curricula with video lessons, practice sets, and score tracking. The most important factor is consistent practice with official LSAC materials, regardless of which study method you choose.
The LSAT registration fee is $248, which includes access to the Credential Assembly Service (CAS) that compiles and sends your law school applications. You can register online at LSAC.org. Additional fees may apply for late registration or test center changes. If the cost is a barrier, LSAC offers fee waivers for candidates who demonstrate financial need — the waiver covers the LSAT fee and reduces CAS costs.
The LSAT is offered multiple times per year, typically in January, February, April, June, August, September, October, and November. You can take the LSAT up to three times in a single testing year, five times in a five-year period, and seven times total. A major change is coming in August 2026: LSAC is transitioning the LSAT from remote proctoring to in-center testing at Prometric test centers. The June 2026 administration will be the last opportunity for remote testing.
