Mensa is the largest, oldest, and best known high-IQ society in the world. It is a non-profit organization open to people who score at the 98th percentile or higher on a standardized, supervised intelligence test. Mensa is formally composed of national groups and the umbrella organization Mensa International.
Mensa (pronounced IPA: [ˈmɛnsə]; means “table” in Latin as is symbolized in the organization’s logo.
Membership
Mensa’s only requirement for membership is that one score at or above the 98th percentile on certain standardized IQ tests. Because different tests are scaled differently, it is not meaningful to compare raw scores between tests, only percentiles. For example, in Malaysia the minimum accepted score on the Cattell test is 148 (full mark 180).
