About the International High IQ Society

The International High IQ Society represents a contemporary movement to stimulate discussions on a variety of intellectual topics. We provide our members with a platform to present ideas, discuss them in a friendly environment, share professional knowledge and enjoy learning again. We hope you will join us!

 

How to join

Membership is open to those who possess an IQ in the top five percent of the population (124 IQ using a 15 standard deviation).

Prospective members can join using certified scores from our online admissions tests, or by submitting evidence of qualifying scores from a prior intelligence test within our approved list of tests.

 

 

We do not accept any unproctored online test that is not officially recognized or certified by the International High IQ Society.

 

Currently there is online IQ test you can take not overseen that we accept. It is the Culture Fair Intelligence Test at 123test.com (USD 8, 99).

  

Other qualifying tests

To qualify using prior intelligence testing scores, we require a demonstrative IQ test score of at least 124, or a raw IQ score in the top fifth percentile on any of the IQ tests specified below. Note that these tests have to be administered by a certified professional such as a psychologist or recognized educational institutions. Unofficial online versions of these tests which you can take unproctored (not overseen) are not accepted. Make sure you upload a photo or scan of the official report with all official credentials, full names and qualifying score.
