Join the 2%
In order to join Mensa, you have to take a Mensa-approved intelligence test that has been properly administered and supervised. And on that test you need to attain a score that places you within the upper 2% of the general population. Contact your local Mensa organisation to find out where and when you can take a test. If you happen to be resident in a country that doesn’t yet have a recognised Mensa group, please contact Mensa International for further information.
Mensa has members in more than 90 countries. Wherever you live, the three stated purposes of Mensa are always the same:
- To identify and foster human intelligence for the benefit of humanity.
- To encourage research into the nature, characteristics and uses of intelligence.
- To provide a stimulating intellectual and social environment for its members.
