Mensa is the largest of the international high-IQ societies. Mensa is for those who rejoice in the exercise of the mind. If you enjoy mental challenges and revel in the interplay of ideas, Mensa is an organization that will stretch your mind and expand your horizons. Mensa is an international society that has one—and only one—unique qualification for membership: you must score in the top two percent of the population on a standardized IQ test.
Mensa’s purposes are to identify and foster human intelligence for the benefit of humanity; to encourage research into the nature, characteristics and uses of intelligence, and to provide a stimulating intellectual and social environment for its members.
How do I join Mensa?
If you have evidence of a score in the top two percent of the general population on a supervised standardized intelligence test, that score may serve as “prior evidence.”
Tests given by an institution/agency/clinic must include the full name of the test, the score and the percentile rank. This documentation must be on the institution/agency/clinic letterhead and signed by the psychologist responsible for the testing, along with the license/certification number of the psychologist, issued by the state in which the psychologist practices.
Evidence in a school transcript must be a school document with a seal. An armed forces record must be a notarized copy.
All prior evidence will be appraised individually and Mensa reserves the right to make the final determination as to the acceptability of the test. There is a one-time processing fee associated with this service.
If you think you may qualify based on past test scores, visit the American Mensa Web site for submitting test scores.
Mensa Admission Tests
You can take the Mensa Admission tests, which are supervised by a certified Mensa proctor. If you score at or above the 98th percentile on one of these tests, you qualify for membership. There is a $40 fee for taking this test. The tests are not valid for people under the age of 14, who can qualify through prior evidence. Mensa does offer a battery of culture-fair, non-language tests.
