IQ to SAT converter

The SAT score people at each IQ typically get, from the same model as the calculator and the SAT to IQ converter. The likely range covers about four in five people at that IQ. The last column shows how rare the IQ itself is in the general population.

People with the same IQ do not get the same SAT score. In this model the SAT explains about 56% of the variation in IQ among test-takers (r = 0.75, squared). The rest is knowledge, preparation, motivation and luck on the day. Around the typical score, one standard deviation is about 155 points, so four in five people at an IQ of 130 land between 1190 and 1580.

The two directions are not inverses

An IQ of 130 points to a typical SAT of 1410. Put 1410 into the SAT to IQ converter and you get 118, not 130. Both directions regress to the mean: very high IQs usually come with high but not quite as high scores, and very high scores usually come from people who are high but not quite as high on IQ. It is the same effect as tall parents having children who are tall, but a little closer to average.

Many converters use percentile matching. They find how rare an IQ of 130 is (about 1 in 44 people), then give the SAT score that is just as rare among test-takers. For 130 that is 1530. It answers “how rare is this?” and treats the SAT as a perfect IQ test.

The SAT is not a perfect IQ test. With a correlation of 0.75 the typical score at an IQ of 130 is 1410, which is 120 lower. The gap grows at the extremes.

This chart uses the current 400 to 1600 scale and the Class of 2025 norms. The digital SAT, introduced in the US in March 2024, kept that scale but made each section adaptive, so the same table applies. No research yet links the digital format to IQ, and we do not claim it changes the answer.

Older scores need care. The SAT was recentred in 1995, which raised typical scores by roughly 100 points, and the 2016 redesign returned to the 400 to 1600 scale used now. A 1300 from 1993 is not a 1300 today. Translate an older score with College Board's concordance tables first, then use the chart. The SAT to IQ converter covers scores going the other way.

Evidence grade: moderate. The SAT is one of the few tests with a published comparison to a general-ability measure. That comparison used the pre-1995 SAT and a military battery, not a Wechsler test and not the digital SAT.

Typical score = SAT mean + r × SAT SD × (IQ − 102) ÷ 14, then mapped through the published percentile table. The spread around it is the SAT SD × √(1 − r²), and the likely range is the typical score plus or minus 1.28 of those, capped at the ends of the scale. For the SAT the middle of that calculation is 1029 + 0.75 × 235 × (IQ − 102) ÷ 14.

Published facts we used

• SAT and ASVAB-derived general ability: r = .82 (N = 917), from Frey and Detterman (2004).
• Class of 2025 SAT mean 1029, SD 235, about 2.0 million test-takers (College Board annual report).
• College Board percentile table for actual test-takers, interpolated between rows.

Assumptions we made

• Mean IQ of SAT test-takers: 102. This is our assumption.
• IQ spread among test-takers: SD 14, a little under 15 because test-takers are a selected group.
• Correlation between SAT and IQ among test-takers: .75, set below the published .82 because selected groups show weaker correlations and the study used an older SAT.
