What do I need to qualify?
To order to join Mensa, you must score in the top 2% on any of a number of standard intelligence tests. If you have already taken such a test, you may submit the scores of that test to qualify. Here is a list of scores of some common test that you can submit as prior evidence to join Mensa.
When can I take a qualifying test?
If you haven't previously taken an intelligence test, you can take one of the tests sponsored by Mensa. We also offer non-standard tests for non-native English speakers and other special situations. Tests are administered locally once or more a month. Click/Tap here for the dates of upcoming proctored tests.
May I take a practice test?
Yes, at-home practice tests are available for $9.99. Click/Tap here to be taken to the online purchase page. You may also try the Mensa Workout quiz for fun.
How can I find my prior evidence?
You may be able to obtain your scores from the appropriate testing agencies. If the agency no longer has a copy of your scores, your high school or college may have your scores as part of your official records.
I have my prior evidence. How do I use it to join?
Visit this page to begin the process. Briefly, you'll submit an official copy of your test scores and the $40 fee.
What happens after I send in my prior evidence?
If your prior evidence is accepted, the National Office will send you an invitation to join and a bill for dues. You'll be able to pay your dues online with a credit card or via direct debit to your bank account.
How do I rejoin?
If you have been a member of American Mensa in the past and would like to rejoin, please contact the National Office at (817) 607.0060  or at . If you know your membership number, you can also pay your dues online with a credit card or via direct debit to your bank account. You do not have to take another test; you need simply pay your dues for the current membership year.
What can I expect after I pay my dues to join or rejoin?
The National Office will process your payment and send you a national Welcome Packet within two weeks of receipt of payment. Depending on when in the month you paid your dues, it will take 2-6 weeks from the date of payment processing before you hear from the local group. Once a month, the National Office sends each local group a list of new members, and that list arrives about the 10th of the following month. Once the list arrives, a local group Welcome Packet containing the current month's local newsletter and Membership Handbook will be sent to you.
