The ESOTERIQ membership is separated into either the GIGA society members or non-the GIGA society members.  Any GIGA member is always automatically welcomed to the ESOTERIQ society.    

Non-GIGA members are required belonging to at least one of the following societies in advance and one test would be limited only per one candidate. Hence, the same tests are prohibited to be listed for the different individuals. 

A member or subscriber of the OLYMPIQ society (at or above IQ190.sd15 performance) 

A listed member of the World Genius Directory (at or above IQ190.sd15 performance) 

A non-belonging candidate of the above may also be considered on a case by case basis. 

WAIS-Ⅳ and Stanford-Binet-Ⅴ are invalid as the ESOTERIQ membership. 

The membership fee is free of charge.
