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. In the meantime, feel free to attend one or more of our upcoming events.
