What is the minimum IQ to get into Mensa?
Mensa's requirement for membership is a score at or above the 98th percentile on certain standardised IQ or other approved intelligence tests, such as the Stanford–Binet Intelligence Scales. The minimum accepted score on the Stanford–Binet is 132, while for the Cattell it is 148.

The society's official objectives are:
to provide a stimulating intellectual and social environment for its members
to identify and foster human intelligence for the benefit of humanity
to encourage research into the nature, characteristics, and uses of intelligence
The society welcomes people from every walk of life whose IQ is in the top two per cent of the population, with the objective of enjoying each other's company and participating in a wide range of social and cultural activities.

Why people join Mensa
Mensa members come from all walks of life and almost every job and profession. Every age group is represented from pre-school children to members in their eighties, nineties and beyond!

Some join because they are looking for intellectual stimulation, others because they feel in some way "disconnected" from the people around them and are looking for other people who "get it". Some join just because they can!

Meet Our Members
What almost all Mensans have in common is the desire to make contact with other lively minds - in person, in print or online - and enjoy being both entertained and informed. The essence of Mensa membership is fun and stimulation for the individual. Mensa members often read voraciously and enjoy the widest range of interests, leisure pursuits and hobbies. The atmosphere at all Mensa meetings is welcoming and convivial. Most Mensans are friendly and sensitive people who welcome the chance to make new friends and expand their horizons.
