The only qualification for Mensa membership is a score in the top 2% of the general population on a supervised standardized test of intelligence. Certain older SAT test scores can also be used as these have been correlated with intelligence tests. You can either submit prior evidence or take two tests that we hold periodically; the testing takes about two hours to complete including a break of 15 minutes. If you are not mathematically inclined, we recommend that you take the Miller Analogy test usually available through a psychologist or University. To be placed on a waiting list of people to be tested, please Email Us.
