The undergraduate majors that post the highest average LSAT scores are generally quantitative and reasoning-heavy fields, led by physics and mathematics and followed by economics, philosophy, and similar analytical majors the low-to-mid 150s (LSAC publishes no single headline average; the median sits near 152). Major matters far less than dedicated preparation, since the LSAT tests learnable reasoning skills on the 120 to 180 scale.

The highest average LSAT scores belong to students from quantitative and logic-heavy majors. Physics and mathematics majors usually lead, with economics, philosophy, and engineering close behind the low-to-mid 150s (LSAC publishes no single headline average; the median sits near 152). These fields build the formal-reasoning and close-reading habits the LSAT measures across its scored sections.
No, your undergraduate major does not determine your LSAT score. The gap between the highest and lowest scoring majors reflects skills practiced in that coursework, not a ceiling on what you can achieve. A dedicated study plan lets a student from any major reach a top score on the 120 to 180 scale see the linked source (see the linked source).
Pre-law students should read LSAT-by-major data as encouragement to build reasoning skills, not as a reason to pick a particular major. Law schools do not favor specific majors; they compare your LSAT and GPA to their medians. Pick a major where you will earn a strong GPA, then prepare specifically for the LSAT your target schools' published 25th-50th-75th percentile figures.
A good LSAT score is one at or above your target schools' medians, whatever your major. Scores above the low-150s national average compete at many programs, while the most selective schools expect high 160s to 170s each school's median LSAT (see its 509 report). Preparation determines your outcome more than your field.
The overall average LSAT score 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). Some majors average above this figure and some below, but the spread reflects practiced skills, so a strong study plan can move any test-taker past the mean.
The LSAT is scored by converting your raw number of correct answers into a scaled score from 120 to 180 through a per-form equating curve, with no penalty for wrong answers. Your major plays no role in the scoring; every test-taker is placed on the same 120 to 180 scale by the same method.
