High IQ Societies

Organizations that limit their membership to individuals who have scored high on the IQ test are referred to as a high IQ society. There are numerous high IQ societies out there and each organization has different requirements for entry. 

These organizations can also be referred to as genius societies because they accept scores for other standardized exams, not just the IQ test.

We will go over each genius society below and review the IQ organizations in-depth to give you a better idea of their offerings and acceptance policies. 

Mensa International

Mensa was founded in 1946 by Roland Berrill and Dr. Lance Ware. In Latin, the term “mensa” means table. The name is fitting because Mensa is a round-table organization where things like race, political beliefs, religious beliefs, and social background are all irrelevant. 

The main requirement to join this high IQ group is that you have scored in the top 2% on an approved test. In other words, you must fall in the 98th percentile for one of the approved tests. 

There are more than 145,000 members that span across 100+ countries. Some activities of the club include lectures, discussions, journals, special-interest groups, and assistance on research projects.

In order for applicants to get into Mensa they will need to submit a qualifying test score. There two ways to prove that you are qualified – you can take a test administered by Mensa or you can submit an approved test score. Listed below are some common tests and scores needed for this IQ society.
