Tests Accepted for Admission to the Mega Society
The Mega Society accepts only the qualifying scores listed here for admission purposes. Please do not submit applications based on any other test
supervised IQ tests do not accurately measure at the one in a million level. For example, the range of the Stanford-Binet is
40–160, which is four standard deviations of 15 about the mean of 100, so that a score of 160 corresponds to a population
rarity of 1 in 30,000.
The Mega Society accepts
members on the basis of untimed,
unsupervised IQ tests that have been normalized using standard statistical methods. There is controversy over whether
such tests measure the same thing as timed, supervised IQ tests.
At the present time, the only tests accepted for admission to the Mega Society
- Langdon Adult Intelligence
Test, IQ 175 (before 1994)
- The Mega Test, 43 raw score (before 1995)
- The Titan Test, 43 raw score

There are no new uncompromised, currently-scored, fully-normed tests with adequate ceiling to discriminate at our target level. This is a serious problem for which a solution will be needed soon. When we are able to locate
acceptable new tests, they
will be listed here.
