What Mensa membership means
Mensa is a social organization for people with high scores on standardized intelligence tests—not a credential for employment or a measure of life success. Members connect through local groups, puzzles, and events worldwide.
National Mensa chapters set their own schedules for supervised testing and may accept scores from certain prior assessments taken elsewhere.

Qualifying scores in general terms
The common threshold is performance at or above the 98th percentile on an approved test. Because different tests use different scales, Mensa publishes conversion tables rather than one universal number.
| Test scale | Example qualifying level | Notes |
|---|---|---|
| SD 15 IQ scale | ~130+ | Top ~2% on many normed tests |
| SD 16 scale | ~132+ | Scale differs—do not mix formulas |
| Cattell scale | ~148+ | Different standard deviation |
| Supervised Mensa battery | Set by proctor | Administered at official sessions |
How people typically qualify
Supervised Mensa test
Many applicants sit a group-administered session arranged by their national organization. Conditions are controlled and scores are official for membership purposes.
Prior evidence
Some chapters accept recent scores from certain clinical or educational batteries documented on paper. Rules change—always check current policies on the official Mensa website for your region.
Online quizzes and Mensa
Free browser quizzes—including FreeIQCheck—are not Mensa admission instruments. An illustrative score of 130+ on a practice site does not grant membership and should not be submitted as evidence.
Use online tools to build comfort with logic puzzles before a supervised session if you choose to pursue one. Expect different formats, timing, and difficulty under proctoring.
Beyond the threshold
Qualifying opens the door to community—not a ranking of human worth. Creativity, empathy, craftsmanship, and persistence matter outside any single test session.
