You already belong. Isn't it about time you joined?

Joined American Mensa, that is. We're an organization bringing smart people like you together to learn new things, talk about their ideas and connect with like minds. We have members around the globe and in your own backyard with plenty of opportunities to make friends at local events, national gatherings and online.

Our only requirement for membership is a score in the top 2 percent on an accepted, standardized intelligence test — that means one in 50 people qualifies for membership. If you'd like to see if you qualify, you can submit scores from a test you've taken in the past or take our test.

If you’re not ready to join but still want a challenge, Mensa has fun to offer! Puzzle-lovers will enjoy taking the Mensa Home Test, gamers test themselves against our games, and there are more than 70 Mensa books for every interest.

We hope you enjoy touring our Web site. If, afterward, you still have questions, don't hesitate to contact a Member Services Representative.

Thank you for reading mental_floss and visiting American Mensa! We appreciate your interest!
