Undergraduate major correlates with average LSAT performance: published analyses of LSAC data have consistently placed analytical fields such as philosophy, physics, mathematics, and economics near the top, while some pre-professional and applied majors average lower. Major matters far less than preparation, though. the low-to-mid 150s (LSAC does not publish a single headline average; the median falls near 152 on the percentile tables)

Analyses of LSAC test-taker data have long found that certain analytical and reading-intensive majors post the highest average LSAT scores. Fields commonly near the top include philosophy, physics, mathematics, economics, and classics, while some applied and pre-professional majors tend to average lower. These are group averages, so individual scores within any major vary enormously and depend far more on preparation than on the major itself.
The table lays out the ranking structure of average LSAT score by undergraduate major, to be filled from a current published analysis of LSAC data. Because these averages shift as data is updated, treat the ordering as approximate until confirmed against the source.
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.
Every major and average in this table should be taken from a current, clearly dated analysis of LSAC LSAT data rather than assumed.
Average LSAT scores by major come from analyses of LSAC data, which records each test-taker's undergraduate field alongside their score. Independent researchers and test-prep organizations periodically publish these breakdowns, so figures can differ slightly by source and year. Because LSAC does not brand any major as better, read these rankings as descriptive correlations, not as advice about what to study.
Choosing a major solely to raise your LSAT score is rarely worth it, because the gaps between majors are group averages that individual preparation can easily overcome. Law schools do not prefer any particular major, and admissions turn on your actual LSAT score and GPA, not your field. Study what you can excel in, then prepare specifically for the LSAT to lift your own score.
A good LSAT score is one at or above the medians of your target law schools on the 120 to 180 scale, regardless of your undergraduate major. Schools compare your actual score to their 50th percentile, not your field of study. Check your target schools' published 25th-50th-75th percentile figures to set your benchmark.
The overall average LSAT score across all test-takers is in the low 150s, near the middle of the 120 to 180 scale, and it varies slightly by testing year. Averages by major sit above or below that overall mean. For the current national figure, see the low-to-mid 150s (LSAC does not publish a single headline average; the median falls near 152 on the percentile tables).
The LSAT is scored by converting your raw score, the number of correct answers, into a scaled 120 to 180 score using your form's conversion table, with no penalty for wrong answers, the same for every major. Since August 2024 the scored sections are two Logical Reasoning sections and one Reading Comprehension section, plus one unscored variable section.
