Membership in Mensa is open to anyone who has achieved a score within the top 2 percent of the general population on an approved intelligence test. More than five million Americans are eligible for membership.

Mensa has members as young as three and as old as 102. However, the Mensa Admissions Test which we administer is only valid for children 14 years and older. Testing for children under 14 is available through private testing services (check the Yellow Pages) and educational institutions.


Mensa’s test battery consists of two timed IQ tests, one short, the other longer, based on proprietary versions of the Wonderlic and Reynolds Adaptable Intelligence Test (RAIT). The test battery takes about two hours to complete, including registration time, costs $60, and can only be taken once. You must be over 14 to take either test and persons between the age of 14 and 18 must have a signed permission of their parent or guardian.


There are two options for taking a test locally. The first is through a supervised testing session given by a proctor from Metropolitan Washington Mensa. Advanced registration is preferred. Most tests are given on Saturdays and take 2 hours to complete. Please bring a photo ID with you, as well as a check for $60 payable to American Mensa Ltd.

To take one of the proctored tests, send email to our Testing Coordinator and provide your name, address, phone number, and the test location and date(s) in which you are interested.

The easiest/quickest option is to schedule a test with a private testing facility. This option is designed with your convenience in mind. You can easily find and schedule a test session near you based on your availability. The cost for this test is $99. Advanced registration is required through American Mensa.


Your GRE, GMAT, SAT, ACT, LSAT, Military test, and many others, may qualify you for membership, regardless of how long ago they were administered.

The National Mensa website lists qualifying scores and provides an online form to submit these scores. The fee for verifying prior evidence is $60.
