What these converters do differently
Most score-to-IQ tools give a single number taken from a percentile chart. That answers how rare a score is, and it stops there. We do three more things.
- Show a range. One test score cannot pin down IQ. Every result comes with the range that about four in five people at that score fall in.
- Correct for regression to the mean. Because a test and IQ are not perfectly correlated, very high scores usually come from people who are high, but not quite as high, on IQ. Each page shows both the most-likely IQ and the higher number you would get if the test were a perfect measure.
- Grade the evidence. Some links between a test and IQ are published and some are assumed. Every page says which, and lists the assumptions, so you can judge for yourself.
The converters compared
| Test | Scale | Example | Evidence grade |
|---|---|---|---|
| SAT | 400 to 1600 (Reading and Writing plus Math, 200 to 800 each) | 1400 → IQ 117 (106 to 129) | Moderate |
| ACT | Composite 1 to 36, the rounded average of the section scores | 28 → IQ 114 (102 to 127) | Moderate |
| ASVAB | AFQT percentile 1 to 99, calculated from four ASVAB subtests | 75 → IQ 108 (97 to 120) | Moderate |
| Wonderlic | 0 to 50, the number of questions answered correctly on the classic version | 30 → IQ 113 (102 to 125) | Limited |
| GRE | Verbal and Quant 130 to 170 each | 320 → IQ 119 (107 to 130) | Weak |
| LSAT | 120 to 180 | 165 → IQ 119 (106 to 131) | Weak |
| GMAT | Focus Edition total 205 to 805, in 10-point steps ending in 5 | 655 → IQ 118 (106 to 131) | Weak |
| CCAT | 0 to 50, the number of questions answered correctly | 30 → IQ 109 (96 to 122) | Weak |
| MCAT | Total 472 to 528 | 512 → IQ 120 (108 to 132) | Weak |
| UCAT | Three cognitive subtests scaled 300 to 900 each (total 900 to 2700), plus Situational Judgement in Bands 1 to 4 | 2300 → IQ 122 (109 to 135) | Weak |
Score to IQ converters: common questions
Can you convert a test score into an IQ?+
Only as an estimate. A score on the SAT, GRE or any other test correlates with IQ but is not the same thing, so a conversion gives a most-likely IQ and a range. No conversion replaces an IQ test taken under supervised, standardised conditions.
Why do these estimates look lower than other converters?+
Many converters match percentiles, so the top 1% of SAT scores becomes an IQ near 135 or higher. That measures rarity, not IQ. Because tests and IQ correlate at about .6 to .8, high scores regress towards average, so the most likely IQ is lower. Each page shows both numbers.
Which conversion is the most reliable?+
The ASVAB (AFQT), because it is scored against a nationally representative sample, and the SAT and ACT, because published studies link them to general ability. GRE, LSAT, GMAT, MCAT, UCAT and CCAT rest on assumptions because no published study links them to IQ.
How wide are the ranges?+
Each range covers about four in five people at that score. It is typically 20 to 25 IQ points wide, roughly plus or minus 10 to 12 points, which reflects how loosely one test score pins down IQ.
Can I use these for a child?+
No. These converters are for adult and adolescent admissions and employment tests, and they are not built to assess children. Speak to a school or educational psychologist about a child.
