Joining Mensa for Children & Youth (< 14 years old)

Younger children join Mensa by submitting a qualifying score from any one of more than 200 tests that Mensa accepts as prior evidence. To find out if a test is acceptable, call 1-800-66-MENSA (63672).

To have your child who is under 14 tested, go to either a licensed psychologist who administers recognized individual IQ tests such as the Stanford-Binet 5 or WISC-IV, or to a specialist in gifted children credentialed for such evaluations. If they are not well-versed in test interpretation for gifted children, go to any of several Web sites, including Davidson Institute, Hoagie’s Gifted Education and Educational Options to learn what the scores indicate. Scores in the 98th percentile or higher qualify a child for Mensa. Most schools administer achievement batteries every other year. These normally include an embedded ability test, usually the Otis-Lennon or the CogAT (Cognitive Ability Test).


These items provide a cornucopia of resources for gifted youth and their parents. Here you will find an extensive site devoted to gifted children in recognition of one of MWW’s goals: to identify and foster human intelligence for the benefit of humanity through scholarships, gifted children’s programs, and other supportive activities.

Whether or not you or your child belong to Mensa, you can both benefit from this section.
