Mensa is the oldest and largest high-IQ society in the world. Founded in 1946 in England, it functions as a non-profit organization. The only requirement for membership is scoring in the top 2% of the general population on a standardized, supervised intelligence test.
To join Mensa, you need to score in the 98th percentile or higher on a standardized, supervised intelligence test.
Because different tests use different scales, the exact numerical score varies:
Stanford-Binet: 132 or higher
Cattell: 148 or higher
Wechsler (WAIS/WISC): 130 or higher
