If you have already taken a qualified IQ test and have evidence of achieving a high enough score, you may be able to join Mensa Canada without attending one of our supervised exam sessions. A list of accepted tests and their respective required scores is below. This procedure can be used by candidates of all ages, especially those under 10 years of age (who are not eligible to take our regular entrance exam).

Please note that Mensa Canada does not accept any test taken over the Internet for admission purposes. All testing must have been given through a school, psychologist, or licensed agency. Mensa Canada’s Constitution requires that any test be standardized and given under supervision by a qualified individual. Internet tests do not meet these criteria.

The test results documentation must include the full name of the test, the score and percentile rank. This documentation must be on institution/agency/clinic letterhead and signed by the psychologist responsible for the testing. If your test was given by an individual psychologist, the documentation must also include the psychologist’s license/certification number issued by the province/state in which the psychologist practices.

The test taker’s name on the documentation must match the name on the application. If it is different for some reason, documentation must be included. For example, a notarized copy of a social insurance card, marriage license or court records to show a new married name.

To apply for membership using prior evidence, please forward the following to the Mensa Canada office:

  1. Your official results (original or photocopy)

  2. Duly filled Prior Evidence Application form (download the form here)

  3. The required $50 fee (cheque or money order made payable to Mensa Canada, or your credit card type, number and expiry date)

Once your score is confirmed you will be invited to join Mensa Canada, and the annual membership fee will be payable at that time.

Example qualifying test scores are below. For tests not listed, or any other questions, please contact the office.


Many intelligence test scores will qualify you for Mensa, but Mensa’s supervisory psychologists will have to individually appraise the documentation. Almost any test with “achievement” in the title is not acceptable for Mensa admission. Mensa Canada does not accept unsupervised testing as proof of eligibility, specifically unsupervised testing administered electronically or via Internet-based tests.
