The undergraduate majors with the highest average LSAT scores are typically quantitative and analytical fields such as physics, mathematics, economics, and philosophy the low-to-mid 150s (LSAC publishes no single headline average; the median sits near 152). Your major is not destiny, though, because deliberate preparation drives your score on the 120 to 180 scale far more than your field of study.

The majors with the highest average LSAT scores are consistently quantitative and reasoning-intensive fields. Physics and mathematics majors typically top the list, followed by economics, philosophy, and other analytical disciplines the low-to-mid 150s (LSAC publishes no single headline average; the median sits near 152). The table ranks the leading majors, with each average score to be confirmed against LSAC data.
The current ranking is best read directly from the source. See the U.S. News Best Law Schools list for the up-to-date order, and each school's ABA Standard 509 report for its median LSAT, GPA, and acceptance rate.
Quantitative and philosophy-heavy majors tend to score higher because their coursework drills the exact skills the LSAT rewards: formal logic, close reading, and structured argument analysis. The pattern reflects skills practiced, not an innate advantage tied to a field. Students in any major who train those reasoning skills directly can match or beat the averages see the linked source (see the linked source).
LSAT-by-major figures come from LSAC data linking test-takers' self-reported undergraduate majors to their scaled scores, often summarized by pre-law analysts. The rankings shift modestly year to year and group some majors broadly see the linked source (see the linked source). Because category sizes differ widely, treat small gaps between adjacent majors as noise rather than meaningful differences.
Treat major-level LSAT averages as background, not a reason to switch majors. Law schools do not prefer specific undergraduate majors; they weigh your actual LSAT score and GPA against their medians. Choose a major you can excel in for a strong GPA, then prepare deliberately for the LSAT to land above your target schools' medians your target schools' published 25th-50th-75th percentile figures.
A good LSAT score is one at or above the median of your target law schools, regardless of your major. Above the low-150s national average is competitive for many programs, while the T14 expect high 160s to 170s each school's median LSAT (see its 509 report). Preparation, not major, gets you there.
The average LSAT score across all test-takers is in the low 150s on the 120 to 180 scale the low-to-mid 150s (LSAC publishes no single headline average; the median sits near 152). Major-level averages sit above or below this overall mean, but the differences reflect skills practiced in that coursework rather than a fixed ceiling for any field.
The LSAT is scored by converting your raw score, the number of questions answered correctly, into a 120 to 180 scaled score through a per-form equating curve, with no penalty for wrong answers. Your undergraduate major has no bearing on this conversion; every test-taker is scored on the same 120 to 180 scale.
