Mensa, the high IQ society, requires an IQ score that places an individual in the top two percent of the general population. This universal percentile requirement translates to different specific scores depending on the standardized intelligence test administered, as various tests use distinct scales and scoring methodologies.
Specific IQ Scores for Mensa Qualification
The core criterion for Mensa membership is achieving a score at or above the 98th percentile. For most IQ tests designed with a mean score of 100 and a standard deviation of 15, the 98th-percentile score is approximately 130.8.
Here is a detailed breakdown of the minimum accepted IQ scores for Mensa based on commonly used standardized tests:
| IQ Test Type | Minimum Accepted Score |
|---|---|
| Stanford–Binet | 132 |
| Cattell | 148 |
| Wechsler Tests (WAIS, WISC) | 130 |
| General IQ Test (Mean 100, SD 15) | 130.8 (98th percentile) |
These varying scores all represent the same achievement: ranking among the top two percent of the population in intellectual ability. For example, a score of 130 on a Wechsler test signifies the same relative intelligence level as a 132 on the Stanford–Binet or a 148 on the Cattell.
How to Qualify for Mensa
To become a member, individuals typically need to demonstrate their IQ through one of the following methods:
- Official Mensa Admissions Test: Many national Mensa branches offer their own supervised intelligence tests designed specifically for membership qualification.
- Prior Evidence from Recognized Tests: Applicants can submit scores from a wide range of previously taken, supervised, standardized intelligence tests. These include tests administered by psychologists, schools, or military services. The submitted score must meet the 98th percentile requirement on the specific scale of the test taken.
