If you want to prove your smarts and connect with other people like you, Mensa could be a great group to join. Since you need to take an intelligence test to become a member, you're probably wondering what it takes to pass. While you can get into Mensa by doing well on an IQ test, there are a lot of other ways you can qualify too. We'll answer all your questions about which tests you can take and how well you need to do to be eligible!

Question 1 of 8:

What is the IQ cutoff for Mensa?

Download Article

It depends on which IQ test you take, but it’s around 130–150. Your Mensa membership isn’t directly based on your IQ score, but you can still use an approved IQ test to join. If you took the Stanford Binet 5 or the Reynolds Intellectual Assessment, scoring an IQ of 130 is enough to get in. For the Stanford Binet or California Test of Mental Maturity, you’ll need at least 132 on your test. If you’ve taken the Cattell IQ test, you need a minimum IQ score of 148.^{[1]

- Each test measures IQ differently, so scoring 132 on one test may be the same as scoring 148 on another. That’s why Mensa avoids only using your IQ score when they consider your membership.

What tests qualify for Mensa?

1
You can take a qualifying in-person test given by Mensa members. You’re able to sign up for a test directly through Mensa as long as you take it at one of their test centers. Just search on the Mensa site to find your nearest local branch and check their schedule for when they’re running the next testing session. You can choose to either wait for a group testing day where multiple people take the exam, or schedule a private test session with an administrator. It all just depends on what type of testing environment you prefer best.^{[2]

- Unfortunately, you cannot qualify for Mensa using an online test you’ve taken at home.

Certain IQ and cognitive ability tests are also approved by Mensa. The Mensa site lists all of the approved tests and scores you may have already taken, so scroll through them and check if you’ve already qualified. If you’re able to use your outside test, just mail an original or notarized copy of your scores to your local Mensa Admissions office and pay the $40 USD fee. They’ll verify your scores and send you an acceptance letter if you qualify. Some common tests and qualifying scores are:^{[3]

Mensa tests are confidential, but the practice tests ask logic questions. Mensa doesn’t post or publish copies of their official tests, so the questions you get are different with each exam. However, practice tests and quizzes on the Mensa site ask multiple questions about choosing the next shape or number in a logical sequence.^{[4]

A culture fair test asks about how shapes relate to one another. The culture fair test is a nonverbal option that you can choose if you aren’t fluent in English or if you don’t want to take the standard test. It tests if you can determine pattern recognition and the relationships between different figures and shapes. Simply request the culture fair test when you sign up so you’re given the right exam.^{[5]

How many times can you take the Mensa test?

You can take each Mensa test once. Once you take the standard Mensa admissions test, you cannot take it again. You can still ask for a culture fair test if you didn’t pass the initial test, but you only get one shot to take it, so wait until you’re ready.^{[9]
