Accepted IQ Test
High range IQ tests such as KIT High Range IQ Test were developed experimentally to measure IQ in the very high range. Based on these high-range IQ tests, GIGA Society assesses extremely high human intelligence, up to IQ 190 (SD 15). The tests being adopted for admission by the GIGA Society are listed below.
Other tests may also be considered for admission. However, WAIS and Stanford-Binet are invalid as admission tests for GIGA Society membership.
