IQ Curious? Join the Club.

Did you know that more than six million people in the U.S. alone qualify for Mensa — that’s one in every 50? Many don’t even realize it, but if you’re reading this, you’ve probably wondered.

If you’re 14 or older, you can take a supervised, standardized test with a certified member volunteer or at one of 400+ approved private testing centers nationwide. Prefer to skip the test? You can submit prior scores from the SAT, Stanford-Binet, or CogAT.

Score in the top 2%, and congratulations — you qualify for American Mensa! All that’s left is to pay your annual dues and join a community of the brightest minds around. Why just wonder if you qualify when you can find out for sure?

Brains, Banter, and Benefits

Mensa isn’t just about IQ — it’s about people who love learning as much as you do. Some like the social aspect of the organization, which includes everything from local game nights to big national events like our Annual Gathering. Others enjoy intellectual events, such as speaker meetings, Colloquiums, and CultureQuest®.

Dive into 120+ Special Interest Groups, from ancient baking to quilting, or connect with fellow Mensans online and around the world through hundreds of online Mensa communities. Volunteer, give back, and even help fund scholarships through the Mensa Education & Research Foundation. Our Local Groups also host speaker nights, have lunch outings, and play games at local and regional game nights.

Plus, enjoy perks that save you time and money through our benefit and service programs — travel, insurance, financial services, publications, and more — constantly updated for members. Smart fun, smart savings, smart community. That’s Mensa.
