How to Join

The only qualification for Mensa membership is a score in the top 2% of the general population on a standardized intelligence test. There are two ways to qualify for Mensa: either take the Mensa Admissions Test, or submit prior evidence. If you were previously a member of Mensa and you have let your membership lapse, you do not need to take another test. You can reinstate your membership on the web.




Prior Evidence

If you've already taken the SAT (prior to 2/94), GRE (prior to 10/01), LSAT, or any of a number of other tests, you may already be eligible for Mensa. Click here for a list of qualifying scores from some acceptable tests. Keep in mind that this is not a complete list - Mensa accepts scores from approximately 200 different tests. Click here for complete information on how to find out if a test you have already taken is acceptable, and how to submit your scores.




Mensa Admissions Test

The Mensa Admissions Test is composed of 2 tests involving logic and deductive reasoning, and are supervised by a certified Mensa proctor. The cost is $40. Scoring at or above the 98th percentile on either test qualifies you for membership in Mensa. Approximately 60 percent of those who take the test prove to be eligible for membership. If English is not your first language, you can arrange to take a non-language based test. Please note that American Mensa cannot test individuals younger than 14 years of age on the test date; however, these prospective members may submit evidence of prior testing to qualify.

Testing FAQ

What should I bring to the test?

How long does the test take?

The Mensa Admissions Test (which is actually composed of two tests) takes about 90 minutes to complete.

Can I still take the test if I have problems with vision, hearing, or muscle coordination?

American Mensa's Supervisory Psychologist advises that testing anyone with circumstances that would make it difficult to take a written test is out of our scope. If you have a condition that would require special accommodations, we recommend that you get tested by a private psychologist using a Mensa accepted test. See the section titled "Prior Evidence" above for more information.

Can I take the test more than once?

The Mensa Admissions Test can be taken only once. However, if your score does not get you accepted into Mensa, you have the option of taking a different test. This can be accomplished by getting tested privately by a psychologist using a Mensa accepted test. See the section titled "Prior Evidence" above for more information.

If you score at or above the 98th percentile on the Mensa Admissions Test, or submit acceptable prior evidence, you will soon receive a letter from the national office with an offer of membership. (Due to legal considerations, Mensa only tells candidates whether or not they have qualified, rather than their IQ number.) Once you have filled out a membership form (online or by mail) and paid your dues (as of 2016, $70 per year, or less for multi-year membership plans) you will receive your membership card.
