Membership of British Mensa, the High IQ Society, is open to anyone who can demonstrate an IQ in the top two per cent of the population, measured by a recognised or approved IQ testing process.Supervised IQ Test and Personality Profile Package Tests can be taken through any registered psychologist.
Mensa does not currently endorse any online IQ tests because they cannot be verified.
The Mensa online workout will give a good indication of how well you might do in an IQ test but will not generate an IQ score.
Prior Evidence Anyone who has shown they have an IQ in the top 2% can submit evidence of this to join Mensa.
Schools Testing We also offer schools the chance to test their pupils aged over 10 and a half .
Lancelot Ware, a British scientist and lawyer, founded Mensa at Lincoln College, in Oxford, England, in 1946.
They had the idea of forming a society for very intelligent people, the only qualification for membership being a high IQ.
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.
Most IQ tests are designed to yield a mean score of 100 with a standard deviation of 15; the 98th-percentile score under these conditions is 130.
