Mensa was founded in 1946 at Oxford University in England by two remarkable individuals: Roland Berrill, an Australian barrister, and Dr. Lancelot Ware, a British scientist and lawyer. The two met by chance on a train journey and discovered they shared a common interest in intelligence testing. They decided to form a society for people with high IQs, and the result was Mensa.
The name "Mensa" comes from the Latin word for "table," symbolizing the organization's goal of creating a round-table society where members meet as equals regardless of background, occupation, race, or any other characteristic. The only qualification for membership is intelligence.
Mensa grew slowly at first but steadily gained recognition. By the 1960s, the organization had established chapters in several countries, including the United States. Today, Mensa has grown to over 150,000 members across more than 100 countries, making it the largest and oldest high-IQ society in the world.
American Mensa, the U.S. chapter, now boasts over 50,000 members, representing one of the largest national groups within Mensa International.
Mensa has three stated purposes:
Nashville is served by Middle Tennessee Mensa, American Mensa Local Chapter 370. The chapter covers the Nashville metropolitan area, Clarksville, Cookeville, and surrounding counties and reports that it was established in 1978.
The local group organizes gatherings and maintains a testing coordinator. Current schedules and requirements should be verified directly with the chapter or American Mensa.
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.
Middle Tennessee Mensa is the local chapter serving Nashville and a broad surrounding region. Reliable public counts for members living specifically within Nashville are not published, so city membership totals should not be estimated.
Adults and qualifying youth may seek testing for Mensa membership, personal documentation, gifted identification, or broader clinical questions. The best test depends on age and intended use. A Mensa Admission Test does not provide the same diagnostic detail as a psychologist's full cognitive evaluation.
The local chapter reports regular gatherings and events across its service area. Event dates, age policies, testing sessions, and locations change; use the current Middle Tennessee Mensa calendar or contact its coordinator.
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.
Applicants may qualify through the Mensa Admission Test or by submitting acceptable prior evidence from an approved standardized test. Accepted tests, dates, score rules, and documentation requirements can change.
Middle Tennessee Mensa states that it offers the admission test in the Nashville area several times per year. Its site says the fee is normally $60, but applicants should verify the current price, promotions, age rules, and available dates directly with American Mensa or the local coordinator.
The admission battery is designed to determine whether the applicant meets Mensa's percentile requirement. It is not a clinical diagnostic evaluation and generally does not provide a detailed cognitive profile for treatment, disability, school, or employment purposes.
Use a licensed psychologist when you need a formal IQ score, diagnostic interpretation, accommodation documentation, or a comprehensive report. Before paying for private testing, confirm that American Mensa currently accepts the selected instrument and report format.
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:
Reliable current membership totals for Nashville or Tennessee are not publicly reported. Middle Tennessee Mensa serves Nashville and surrounding Middle Tennessee counties; consult the local group or American Mensa for current 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.
As of July 2026, American Mensa lists local-group admission testing at $60, private testing at $99, and annual dues at $107. Fees can change, so verify current pricing directly. Independent psychological testing is priced separately by the evaluator.
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.
No. Mensa does not accept online tests for admission. The test must be administered in person by a qualified proctor in a supervised environment. This includes the Mensa Admission Test and any prior evidence you submit.
Yes. Children can qualify for Mensa by scoring at the 98th percentile on an age-normed test. Parents can submit a psychologist's report directly to American Mensa. There is also a gifted youth program for younger members.
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.
