Mensa was founded in England in 1946 by Roland Berrill and Dr. Lancelot Ware. The name comes from the Latin word for “table,” reflecting the concept of members meeting as equals. Membership is based on qualifying performance on an accepted standardized intelligence test.
The organization expanded internationally and developed national groups, local chapters, publications, scholarship programs, gifted-youth resources, special-interest groups, and social events. American Mensa is the U.S. national organization.
Tallahassee residents participate through the American Mensa local group serving North Florida and through regional or national events, online communities, special-interest groups, scholarships, and gifted-youth resources. The assigned local group, volunteer testing schedule, and meeting locations can change, so verify them through American Mensa’s current directory.
To qualify for Mensa, you must score at or above the 98th percentile on an approved standardized intelligence test. This means performing better than 98 out of every 100 people who take the same test.
Note that different tests use different standard deviations, which is why the qualifying scores vary. The consistent requirement is the 98th percentile.
American Mensa organizes members through local groups and regions. Tallahassee is served by the current North Florida-area local group identified in American Mensa’s directory. Membership geography is broader than the city, and event or testing availability depends on volunteers and registration.
Adults and older teens may pursue qualification for community, personal curiosity, gifted-peer connection, scholarships, or prior-evidence documentation. Children generally qualify through accepted prior evidence under current youth rules rather than simply taking an adult local admission test.
Tallahassee-area members may use local or statewide meetings, regional gatherings, newsletters, online groups, scholarships, special-interest groups, and gifted-youth resources. Membership does not replace educational, clinical, or career evaluation.
Florida State University Psychology Clinic, 1107 West Call Street, Tallahassee, FL 32306-4303, publishes intellectual, gifted, learning, ADHD, and diagnostic assessment services for children, adolescents, and adults. Call (850) 644-3006 to confirm whether the clinic currently administers a test and score type accepted by American Mensa and whether its supervised training-clinic documentation meets prior-evidence rules.
A clinical evaluation may be more detailed and expensive than a Mensa admission session but can provide index-level interpretation and recommendations. An admission test is designed for membership qualification and is not a diagnosis, disability evaluation, learning assessment, or career report.
American Mensa accepts scores from approximately 200 different standardized intelligence tests. Tests must be administered by a neutral and qualified third party in a traditional testing environment.
There are two primary pathways to Mensa membership:
American Mensa offers local-group test sessions and private testing at approved facilities. Availability near Tallahassee depends on the current San Francisco central Florida County and national scheduling systems. Key details:
The Mensa Admission Test is specifically designed for admission to Mensa and does not provide a detailed IQ score or report. You will only be notified whether you qualified for membership. If you want a detailed IQ report with index scores, you should take a professionally administered test like WAIS-IV or SB-5 with a licensed psychologist.
Check American Mensa’s current accepted-test and qualifying-score list before scheduling. Ask whether the evaluator will provide the required original or certified documentation. Confirm that the test edition, score type, age norm, and administration conditions are acceptable. Do not assume a screening test, online quiz, abbreviated estimate, school gifted label, or percentile from an unaccepted measure will qualify.
Mensa was founded in 1946 in Oxford, England by Roland Berrill and Dr. Lancelot Ware. The name comes from the Latin word for "table," symbolizing a round-table society where all members are equal. Today, Mensa has over 150,000 members in more than 100 countries. American Mensa has over 50,000 members.
The requirement is scoring at or above the 98th percentile on an approved intelligence test. This translates to:
There is no authoritative public Tallahassee-only membership count. Tallahassee Valley Mensa and the official American Mensa directory provide the most reliable current chapter information.
The Mensa Admission Test takes 1-2 hours total, including check-in and instructions. The two test batteries are timed and typically run between 20-25 minutes each.
Current official pricing lists local-group admission testing at $60, private testing at $99, and primary annual membership dues at $107. Rates and promotions can change. Professional IQ testing with a licensed psychologist typically costs more because it includes individualized administration, interpretation, feedback, and often a written report.
Yes. Mensa accepts qualifying scores from tests taken at any point in your life, including childhood. You need to obtain an official report from the testing service or school showing your score. Many members join using SAT scores from decades ago.
An unsupervised at-home online quiz cannot qualify you for membership. American Mensa offers a nonqualifying online practice test and supervised admission options, including electronically administered private testing at approved facilities. Prior evidence must meet current documentation and administration rules.
Yes. Yes. Candidates age 14 and older may use current supervised testing options, while children under 14 qualify through accepted prior evidence from school or professional testing. Documentation must meet American Mensa's current youth-admission requirements.
The Mensa Admission Test is designed only to determine if you qualify for membership and does not provide a detailed score report. Professional IQ testing (WAIS-IV, SB-5) provides a comprehensive report with Full Scale IQ, index scores, strengths, and weaknesses. Professional testing is better if you need a detailed analysis for school, career, or clinical purposes.
Mensa is primarily a social organization that provides community for people with high IQs. Activities include social events, discussion groups, lectures, game nights, and special interest groups. Mensa also supports gifted education initiatives, scholarships, and research into intelligence.
