LSAT to IQ converter

The LSAT is built to test the reasoning skills law students need, so it is probably one of the cleaner reasoning-based tests here. But no study has published how closely it tracks IQ, so the link used here is an assumption. Expect the true value for any one person to sit anywhere in the range shown.

Every LSAT score, from the same model as the calculator. The likely range covers about four in five people at that score. The last column is the IQ you would get if the LSAT measured IQ perfectly, which is the number most other charts show.

Going the other way, this is the LSAT score people at each IQ typically get. Scores at the same IQ vary a lot, so the range matters more than the middle figure.

The LSAT tests reading and reasoning with almost no subject knowledge required. Logical Reasoning asks you to find flaws in short arguments and to work out what follows from a set of premises. Reading Comprehension asks for close reading of dense passages.

That design makes it a reasonable stand-in for verbal and analytical reasoning. It is also unusually trainable. The old Logic Games section, which was dropped in August 2024, was the clearest example: people improved by learning the technique, which is why prep courses moved scores by many points there. Removing it removed the most trainable section, though scores on the remaining sections still respond to practice.

We could not find any published study correlating the LSAT with an IQ battery. A figure of .36 circulates online, but it traces to an unsourced student post and looks like a validity figure for law school grades, not for IQ. The correlation used here is an assumption of .60.

LSAT test-takers are college graduates who have chosen to apply to law school. They are, on average, above the general population in ability, so a mid-range LSAT score means something different from a mid-range score on a test everyone takes. This converter assumes law applicants average about 111 in IQ, with a narrower spread than the general population.

That assumption raises every estimate by roughly ten points compared with treating the LSAT percentile as a general-population percentile. It is also the assumption you should question if you disagree with the number you see: change it and the whole table shifts.

Mensa treats the LSAT as an acceptable qualifying test for admission, based on the 95th percentile for tests taken after 1982. The percentile is what matters, and the exact score that corresponds to it changes as LSAC updates its tables, at about 170 or 171 in current data.

The scale is still 120 to 180. LSAC has said scores from before and after the removal of Logic Games remain comparable, and the percentile table here pools the 2023-24, 2024-25 and 2025-26 testing years so it covers the transition.

If your score is from before 2024 it is still a valid score. But the mix of people who take the LSAT has also changed, with volumes up sharply in recent years, so treat older percentile tables in books and guides as approximate.

Percentiles compare you with other recent test-takers. The estimated IQ column shows the most likely value, with the likely range in brackets.

There is no official LSAT to IQ conversion. LSAC does not publish one. What we can do honestly is treat the LSAT as a good but imperfect signal of general ability. We place your score among LSAT test-takers, assume how able that group is on average, and use the correlation between the two to predict the most likely IQ. Because the correlation is below 1, high and low scores are pulled towards the middle. That is why the estimate comes with a range.

Evidence grade: weak. LSAC's percentile table is official and current. Whether the LSAT tracks IQ closely has not been published, so the IQ link is an assumption.

Published facts we used

• Percent of test-takers below each score from 125 to 180 (LSAC LSAT percentiles, pooled 2023-24 to 2025-26).
• The mean of about 153 and SD of about 11 are our calculations from that table, not LSAC figures.

Assumptions we made

• Mean IQ of LSAT test-takers: 111. College graduates applying to law school.
• IQ spread among test-takers: SD 12.
• Correlation between LSAT and IQ among test-takers: .60. No published value exists.
