Mensa IQ eligibility in context
Mensa IQ eligibility on approved tests usually means scoring at or above the top 2% of a norm group — often summarized as the 98th percentile. On SD-15 scales that is frequently near IQ 130, but cutoffs vary by test and sitting.
Use this calculator after reading Mensa IQ test practice guidance, then rehearse with Mensa practice test matrices before any official pre-test.

FAQ
What IQ score is needed for Mensa?
Many chapters require scoring at or above the 98th percentile on an approved supervised test. On a Wechsler-style scale (SD 15), that is often around IQ 130 — but the exact cutoff depends on the test and norm group used at the sitting.
Does this calculator grant Mensa membership?
No. This is an educational percentile estimator only. Mensa admission requires an official supervised test administered under society rules.
Why 98th percentile?
Mensa International describes membership as the top 2% of the population on approved intelligence tests. The 98th percentile is the usual shorthand for that threshold when scores are reported as population percentiles.
