LSAT to IQ: What a 160, 170 or 180 LSAT Suggests
LSAT to IQ is a rough estimate at best. The LSAT is a hard reasoning test, so a 170 usually points to strong logical and reading skills (think IQ somewhere in the mid-120s to low 130s), but LSAC publishes no LSAT to IQ chart, the test focuses on one slice of intelligence, and prep moves scores a lot.

Can you convert LSAT to IQ?
You can make an educated guess. You can't make a real conversion.
The LSAT is the law school admission test used in the US and Canada. It's scored from 120 to 180, with the median usually landing around 150-152. It measures:
- Logical reasoning: reading short arguments and finding assumptions, flaws or what must be true.
- Reading comprehension: dense passages, often on law, science or humanities.
- (Formerly) analytical reasoning, aka "logic games," which was removed starting with the August 2024 test.
That's a narrow, deep test of verbal-logical reasoning. An IQ test covers more ground, including patterns, numbers and spatial stuff. So an lsat to iq conversion always involves some stretching.
Why LSAT takers skew high
Everyone taking the LSAT already has (or is finishing) a degree and wants to go to law school. That's a group that averages above the general population on reasoning. So the 50th percentile on the LSAT is not the same as an IQ of 100. That selection effect is what every good lsat to iq calculator has to adjust for, and most don't.
LSAT to IQ chart: 150 to 180
Here's a rough LSAT to IQ conversion chart. It matches approximate LSAT percentiles, then adjusts for the fact that LSAT takers are a select group.
| LSAT score | Approx. LSAT percentile | Rough IQ estimate |
|---|---|---|
| 150 | ~45th | 105-112 |
| 155 | ~63rd | 110-116 |
| 160 | ~80th | 114-121 |
| 165 | ~91st | 119-126 |
| 170 | ~97th | 124-131 |
| 175 | ~99.5th | 129-136 |
| 180 | ~99.9th | 133+ |
Percentiles shift slightly each testing year, so use LSAC's current tables for your exact spot.
160 LSAT to IQ
A 160 is solid, around the 80th percentile of test-takers. As an lsat to iq score, it suggests something in the mid-to-high 110s. Plenty of good law schools admit students in this range.
165 LSAT to IQ
A 165 is around the top 10%. Rough estimate: low-to-mid 120s. This is where the LSAT starts rewarding careful, precise reading.
170 LSAT to IQ
A 170 is roughly the top 2-3%. Estimates land around 124 to 131. Getting here almost always takes both real reasoning chops and lots of practice.
180 LSAT to IQ
A perfect 180 is extremely rare. It points to excellent logical reasoning, but the test can't show how far above the ceiling someone is. So the most honest 180 lsat to iq answer is "high, exact number unknown."
What the LSAT actually measures
Law schools use the LSAT because it predicts first-year law school grades, not because it's an IQ test. Here's what it's really checking:
- Can you find the hidden assumption? Every argument rests on something unsaid.
- Can you spot the flaw? Correlation vs causation, sampling issues, overgeneralizing.
- Can you read slowly and exactly? "Some" vs "most" vs "all" matters.
- Can you hold several conditions in your head? This used to be the core of logic games.
Think about the group chat when someone says "everyone at our school vapes." The LSAT brain immediately goes: "everyone? Or everyone you've seen at one party?" That's the skill.
Is the LSAT an IQ test?
No. It's a focused test of verbal and logical reasoning. It overlaps with IQ, but it doesn't touch visual patterns or number series much, and it rewards prep heavily. Many people raise their LSAT by 10+ points with months of practice, which would be weird for a pure IQ measure.
Judging your own logic is hard. You can reread an argument five times and still not know if your reasoning is sharp or you just got lucky. IQ Tester scores your logic questions alongside number series, verbal analogy and pattern questions, weights harder ones more, and shows which categories are strongest, so you know exactly what to practice.

Correlation: how tight is it?
Here's the honest part: there isn't a famous study pinning down an exact LSAT to IQ correlation the way there is for the SAT (about 0.8 with general intelligence, from Frey and Detterman in 2004) or the ACT (about 0.77, from Koenig and colleagues in 2008).
What we can reasonably say:
- The LSAT is a demanding reasoning test, so it very likely correlates well with IQ.
- Selection (only grads take it) and heavy prep make the relationship messier.
- Anyone quoting an exact LSAT to IQ correlation number should show their source.
For comparison, see our SAT score to IQ conversion and GRE to IQ conversion guides, which have similar caveats.
Logic games and reasoning skills
Logic games were the LSAT section people either loved or hated. They looked like this:
Six friends sit in a row. Maya sits next to Jordan. Priya isn't at either end. If Leo sits in seat 2, who must sit in seat 5?
Even though the LSAT dropped logic games in 2024, the skill behind them is still gold:
- Diagramming: sketch the setup instead of juggling it in your head.
- Conditional rules: "if A then B" does not mean "if B then A."
- Must vs could: know the difference between what has to be true and what might be.
These same habits show up in IQ logic questions, in coding, and in winning arguments in the group chat. If you're into games, compare this with the research on chess Elo to IQ, which shows a similar "related, but not the same thing" story.
Practise logical reasoning
Want your logic to get sharper, whether for the LSAT or just life? Try this five-minute daily routine:
- One argument a day. Take a headline or a viral post and ask: what's the conclusion, and what's it assuming?
- Name the flaw. Is it a small sample? Correlation called causation? An "all" that should be "some"?
- Do three logic puzzles. Short and focused beats long and rare.
- Say your reasoning out loud. If you can't explain it, you don't have it yet.
- Track what trips you up. Patterns in your mistakes are where the growth is.
UK readers: practise (UK) and practice (US) are the same thing here. And if you're in Canada, the LSAT is your law school test too, so this applies directly.

FAQ
What IQ is a 170 on the LSAT?
A 170 roughly suggests an IQ in the mid-120s to low 130s. It's an estimate, since the LSAT measures logical and reading skills after prep, not IQ directly.
Is there an official LSAT to IQ conversion chart?
No. LSAC publishes percentiles, not IQ equivalents. Any LSAT to IQ conversion chart online is an unofficial estimate.
Does the LSAT measure intelligence?
It measures part of it: verbal and logical reasoning, plus careful reading. It doesn't really test visual patterns or number skills, and prep can raise scores a lot.
Are logic games still on the LSAT?
No. Starting with the August 2024 test, LSAC removed the analytical reasoning (logic games) section and replaced it with a second logical reasoning section.
What does Reddit say about LSAT to IQ?
Reddit threads usually share hobby-site charts and personal stories. They can be fun, but they rarely adjust for the fact that LSAT takers are a select, heavily prepped group.
