How To Qualify for Mensa

Mensa membership is open to individuals who score in the top 2 percent of the general population on a standardized IQ test.

You can be invited to join American Mensa in one of two ways:

Submit prior evidence of an IQ score at or above the 98th percentile of the general population: You can submit a score from a supervised, standardized test. American Mensa accepts more than 200 qualifying tests, including the Stanford Binet, the LSAT, the CogAT or the Cattell. Many people find this a quick and easy way to qualify for Mensa membership, because they can qualify on tests they have already taken at some point in their lives. The final decision of evaluating such prior evidence rests with the American Mensa National Office under the authority of the supervisory psychologist.  You can review a partial list of tests and qualifying scores on the American Mensa Web Site.


Take the Mensa Admission Test Battery: If you’re age 14 or older, you can take a standardized test from one of our local certified member volunteer test proctors or at a local testing center.

In either case, if your score is in the top 2% of the population, you qualify for membership in Mensa. Then, it’s just a matter of joining and paying your dues.

A Practice Test

Wondering how you can take a peek at some of the kinds of questions featured on the standard Mensa  test? You can do that right now with the official Mensa Practice Test.  The Mensa Practice Test (formerly known as the Mensa Home Test) is a fun way to discover if you may be Mensa material. While this timed, on-line test will not qualify you for membership,  it may give you a better understanding of the types of questions you’ll find when you take the standard Mensa Test.

For a nominal fee, you can take the Mensa Practice Test online now, and it will be scored immediately. The test is timed and takes 30 minutes to complete.
