What does an IQ of 152 mean?

  • 152 is above the top-2% line Mensa uses for admission (130 on the Wechsler scales), if it comes from an approved, supervised test.

Scores from 145 to 159 are three to four standard deviations above the mean: about 1 in 740 people score above 145 and about 1 in 8,100 above 155. The Stanford-Binet 5 calls this range "very gifted or highly advanced"; on the WISC-V it is part of the Extremely High range that starts at 130.

People in this range typically learn abstract material very quickly and can handle complex problems far beyond what is typical for their age. Children here are often accelerated at school or placed in specialist gifted programmes.

At this level tests begin to run out of difficult questions, so measurement error grows. Two good tests can easily disagree by 5 to 10 points, and a high score is a strong sign of exceptional reasoning rather than an exact rank.

IQ 152 on other scales and tests

Different tests spread scores differently. The same rank as an IQ of 152 on an SD-15 test gives these numbers elsewhere:

SD 24: Cattell III B183–

How precise is an IQ score of 152?

No test measures IQ exactly. On individually administered tests such as the WAIS, the full-scale score comes with a 95% confidence interval of roughly ±5 points, so a result of 152 is best read as "probably somewhere between 147 and 157". Scores can also shift a few points between different tests or after a few years.

Precision also drops near the top of the scale. Standard WAIS and WISC norms end at 160, and a norming sample of a few thousand people contains almost nobody at these levels, so scores this high are estimates built on very few cases.

Online tests, including ours, are self-assessments. They are useful for curiosity and practice, but they are not a substitute for an assessment by a psychologist.
