1What is Mensa?

Mensa (Latin for "table") was founded in 1946 by Roland Berrill and Dr. Lance Ware in Oxford, England. The name symbolizes a round-table society where all members are equals, regardless of background, profession, or social status—united only by their high intelligence.

Today, Mensa has three stated purposes: to identify and foster human intelligence for the benefit of humanity, to encourage research into intelligence, and to provide a stimulating intellectual and social environment for its members.

2How to Qualify for Mensa

To join Mensa, you must score at or above the 98th percentile on a standardized intelligence test. This means you perform better than 98% of the general population. There are two main ways to qualify:

Option 1: Prior Evidence

Submit qualifying scores from approved standardized tests you've already taken. Mensa accepts over 200 different tests.

Commonly Accepted Tests:

  • • Stanford-Binet (IQ 132+)
  • • WAIS-IV (IQ 130+)
  • • WISC-V (IQ 130+)
  • • SAT (pre-1995: 1250+)
  • • GRE (pre-2002: 1250+)
  • • LSAT (95th percentile+)

Option 2: Take Mensa Test

Take the official Mensa Admission Test administered by Mensa proctors. This is the most common path to membership.

Test Details:

  • • Cost: $40-$60 (varies by location)
  • • Duration: ~2 hours
  • • Format: Paper-based, proctored
  • • Retake: Wait 12 months
  • • Results: 4-6 weeks
  • • Pass rate: ~15-20%

Important: Score Requirements Vary by Test

Different tests have different qualifying scores because they're normed differently. For example:

  • • Stanford-Binet: 132+ (98th percentile)
  • • Wechsler scales: 130+ (98th percentile)
  • • Cattell III B: 148+ (98th percentile)

Check Mensa's official website for the complete list of accepted tests and qualifying scores.

4How to Prepare for the Mensa Test

While you can't "study" for an IQ test in the traditional sense, you can prepare strategically to perform at your best. Here's how:

Effective Preparation

  • Practice Similar Tests: Take practice IQ tests to familiarize yourself with question formats
  • Time Management: Practice working quickly and accurately under time pressure
  • Pattern Recognition: Work on puzzles, Sudoku, and pattern-based games
  • Mental Math: Practice quick calculations without a calculator
  • Rest Well: Get 8+ hours of sleep the night before

Ineffective Preparation

  • Cramming: Last-minute intensive studying doesn't improve IQ scores
  • Memorization: Trying to memorize specific questions or answers
  • Over-practicing: Taking the same practice test repeatedly
  • Stress: Excessive anxiety about the test outcome
  • Shortcuts: Looking for "tricks" or "hacks" to beat the test

Frequently Asked Questions

What IQ score do I need to join Mensa?
You need to score at or above the 98th percentile on a standardized intelligence test. For most IQ tests, this translates to a score of 130 or higher (on tests normed to mean=100, SD=15). However, the exact score requirement varies by test. Check Mensa's official website for specific qualifying scores for different tests.
Can I retake the Mensa test if I don't qualify?
Yes, but you must wait 12 months before retaking the test. This waiting period prevents practice effects from inflating scores. If you don't qualify on your first attempt, use the year to work on cognitive skills through puzzles, reading, and mental exercises.
Is Mensa membership worth it?
This depends on your goals. If you value intellectual stimulation, networking with like-minded individuals, and access to exclusive events and resources, Mensa can be very worthwhile. Many members cite the social connections and intellectual discussions as the primary benefits. However, if you're only interested in the credential, the annual membership fee may not provide sufficient value.
Can I use my SAT or GRE scores to join Mensa?
Possibly, but only for tests taken before certain dates. SAT scores from before 1995 and GRE scores from before 2002 are accepted if they meet the qualifying thresholds. More recent versions of these tests are not accepted because they were redesigned and no longer correlate as strongly with IQ. Check Mensa's website for the complete list of accepted tests and dates.
What happens if I qualify for Mensa?
If you score at or above the 98th percentile, you'll receive a letter in 4-6 weeks inviting you to join Mensa. The letter includes membership information and an application form. You can then choose to join by paying the annual membership fee. Membership is not automatic—you must actively choose to join and pay dues.
Are there age requirements for Mensa?
There is no minimum age to take the Mensa test or join Mensa. However, children under 14 must take age-appropriate tests (like the WISC-V) administered by a licensed psychologist rather than the standard Mensa Admission Test. Mensa has special programs for gifted children and young members.
