What is Mensa and how can you qualify for admission to a High IQ Society?
High IQ Societies like Mensa limit their membership to include only individuals who have scored in the 98th percentile on an approved intelligence quotient (IQ) test.
Mensa is the largest, oldest and most renowned high intelligence society in the world. It is also incredibly difficult to get into. To qualify for membership to Mensa, you must score in the top 2% of all people taking an approved intelligence or aptitude test. This sole requirement is usually met with an IQ test score of approximately 130 or above. Eligible candidates for Mensa membership need to supply proof of their qualifying test scores and pay applicable membership dues to join. If you’re interested in finding out if you are Mensa material, our practice test can help you prepare for the actual Mensa exam. Please note, the tests on this site are for entertainment purposes only. You won’t find a real IQ test free online, but you can learn more about the different types of IQ tests available on this site and contact a local organization or professional psychologist who can help you schedule one.
