What is Mensa? & Mensa Scores

Founded in 1946 by Roland Berrill, an Australian barrister, and Dr. Lancelot Ware, a British scientist and lawyer, Mensa is a high IQ society – the only qualification for Mensa membership being an IQ is in the top 2% of the population. Mensa members are also known as ‘Mensans’.

Mensa membership score on the IQ bell curve

The word ‘Mensa’ comprises two Latin words: mens, which means “mind” and mensa, which means “table”, meaning that it is a round-table (open discussion) society of minds.

There are now around 100,000 Mensans in 100 countries throughout the world. There are active Mensa organizations in over 40 countries on every continent except Antarctica.The website for Mensa International can be found here. Websites for national Mensa organisations can be found here.


Why Join Mensa?

Different people have different reasons for why they want to join Mensa. Here are some of them.

1.Personal challenge. Mensa membership is an accomplishment like running a marathon.

2. Intellectual stimulation. You can find intellectual resources to exercise your brain in national magazines, in local newsletters, and at regional, national and international conventions. Mensans (Mensa members) have a profusion of special interest groups. To quote from Mensa International.

Whatever your passion, there’s almost certain to be a Special Interest Group (SIG) filled with other Mensans who share it! Mensa offers approximately 200 SIGs, in mind-boggling profusion from African Violets to zoology. Along the way you’ll find microbiology, and systems analysis, but you’ll also find Sherlock Holmes, chocolate and Star Trek. There are the expected: biochemistry, space science, economics — and the unexpected: poker, roller-skating, scuba diving, UFOs and witchcraft. There are SIGs for breadmaking, wine making, cartooning, silversmithing, and clowning. Heraldry, semantics and Egyptology co-exist with beekeeping, motorcycling and tap dancing. Sports SIGs cover the classics (baseball, basketball, and football) and the not-so-classic (skeet shooting, hang gliding, skydiving). And any Mensan who can’t find a SIG to join can easily start one.

3. Prestige. Mensa puts you in a cerebral elite!  There have been reports that job applications have been easier with Mensa membership on your CV – particularly if the hiring person is also a Mensan.

4. Social life. Local groups meet monthly or even more regularly. There are widely attended annual conventions offering workshops, seminars, and parties.

5. Mensa publications. You will receive your national magazine with contributions by Mensans on a wide variety of subjects. In some countries, in addition to the national magazine you may receive lively local newsletters. Mensa also publishes its own research journal on IQ related topics – The Mensa Research Journal – for the general public.

6. Perks. In some countries Mensa sponsors a members-only credit card and insurance program. There is also a program that aids traveling Mensans.

Mensa Requirement & Mensa Testing

Mensa membership is open to people who score at the 98th percentile or higher on a standardized, supervised intelligence test.

American Mensa accepts scores from approximately 200 different standardized intelligence tests, as well as Mensa’s own dedicated Mensa test. Some of these test one’s spatial and analytical abilities using non-verbal questions only. We call these tests “culture fair” because they don’t require general knowledge, vocabulary or math skills that are learned in school and which differ from culture to culture. Other IQ tests include questions that present verbal analogies or puzzles that test comprehension and mathematical ability.

A list of some of the authorized IQ tests for Mensa membership are listed here.

Results from tests given by an institution, agency or clinic must include the full name of the test, the score and the percentile rank. This documentation must be on the letterhead of the institution, agency or clinic; it also must be signed by the psychologist responsible for the testing and must include the psychologist’s license/certification number as issued by the state in which the psychologist practices. Applications are individually assessed by Mensa. This month the evaluation is free. Normally it is $40.
