How to Qualify for Mensa — Percentiles, Tests, and Prior Evidence
Step-by-step guide to the 98th percentile threshold and accepted test types.
To qualify for Mensa, you need a supervised score at or above the 98th percentile on an approved instrument — or equivalent prior evidence from a licensed psychologist.
Official chapter sitting
National Mensa organizations schedule matrix or culture-fair batteries with trained administrators.
Prior evidence route
WAIS-IV, Stanford-Binet, or other listed clinical tests administered by a licensed professional may qualify if scores meet chapter rules.
Online practice role
Matrix practice on CertifiedIQ estimates readiness; it does not substitute for a proctored society exam.
