Question 1

What IQ do I need to join Mensa?

Accepted Answer

You need to score in the top 2% of the population (98th percentile). On tests with SD=15 (like WAIS, Stanford-Binet), this is approximately IQ 130+. On Cattell tests (SD=24), this is approximately IQ 148+. The exact qualifying score depends on the specific test.

Question 2

Can I use prior test scores to join Mensa?

Accepted Answer

Yes! Mensa accepts scores from over 200 standardized IQ tests including WAIS, Stanford-Binet, Cattell, GRE (older versions), LSAT, SAT (pre-2016), ACT, and many others. Contact your national Mensa for the complete list of accepted tests and qualifying scores.

Question 3

How hard is the Mensa test?

Accepted Answer

By definition, only 2% of the population can qualify. However, the tests measure innate reasoning ability rather than learned knowledge. If you consistently score well on IQ-type tests and puzzles, you have a good chance. The Mensa Home Test can help you gauge your readiness.

Question 4

What are the benefits of Mensa membership?

Accepted Answer

Benefits include: access to 200+ Special Interest Groups (SIGs), local and national events, Annual Gathering, Mensa publications, member forums, networking opportunities, scholarships (for members' children), and discounts from various partners.

Question 5

Is the Home Test the same as the official test?

Accepted Answer

No, the Home Test ($18) is a practice indicator only and cannot be used for admission. It's designed to help you decide if you should take the supervised test. If you score well on the Home Test, you're likely to pass the official supervised test.

Question 6

Can I retake the Mensa test if I fail?

Accepted Answer

Yes, you can retake after a waiting period (typically 6-12 months depending on the country). However, IQ test scores tend to be fairly consistent, so significant improvement is uncommon without major life changes.

Question 7

How do I prepare for the Mensa test?

Accepted Answer

Practice with pattern recognition puzzles, matrix problems, number sequences, and verbal analogies. Take the Home Test to familiarize yourself with the format. Get good sleep before the test. However, since IQ tests measure innate ability, intensive studying has limited impact.

Question 8

What tests are given at a Mensa testing session?

Accepted Answer

In the US, two tests are typically given: a culture-fair nonverbal test (similar to Raven's Progressive Matrices) and a verbal reasoning test (similar to Wonderlic). You only need to qualify on ONE test to join. Specific tests vary by country.

Question 9

Is Mensa membership worth it?

Accepted Answer

It depends on your goals. If you want intellectual community, networking, and social opportunities with like-minded people, it can be very valuable. If you just want IQ validation, the test alone provides that. Many members find the SIGs and events most worthwhile.

Question 10

What percentage of people pass the Mensa test?

Accepted Answer

Among people who take the supervised test, about 50% qualify. However, this is higher than the general population's 2% because those who take the test are self-selected - they usually have reason to believe they might qualify.
