The History of Mensa
The Founding: Oxford, England (1946)
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.
The Early Years
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's Three Purposes
Mensa has three stated purposes:
- To identify and foster human intelligence for the benefit of humanity
- To encourage research into intelligence and its characteristics
- To provide a stimulating intellectual and social environment for its members
Clarksville's Connection to Mensa
Clarksville is included in the service area of Middle Tennessee Mensa, American Mensa Local Chapter 370 in Region 5. The chapter was established in March 1978 and includes the Nashville metropolitan area, Clarksville, Cookeville, and surrounding counties. This regional structure gives Clarksville residents access to a broader Middle Tennessee network rather than a city-only chapter.
Mensa Qualifying Scores
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.
Qualifying Scores by Test
Note that different tests use different standard deviations, which is why the qualifying scores vary. The consistent requirement is the 98th percentile.

Clarksville residents who qualify can participate through Middle Tennessee Mensa.

Motivation varies: some seek social connection, special-interest groups, lectures, newsletters, regional gatherings, or confirmation of prior qualifying evidence.

The Mensa Testing Process
Two Ways to Qualify
There are two primary pathways to Mensa membership:
- Take the Mensa Admission Test: A supervised test administered by Mensa proctors
- Submit prior evidence: If you've already taken an approved test and scored at the 98th percentile, you can submit those scores
The Mensa Admission Test
The Mensa Admission Test is administered in supervised sessions held in cities nationwide, including Clarksville. Key details:
- Duration: 1-2 hours total
- Format: Two separate timed tests (the Wonderlic and Culture Fair tests)

Important: The Test is for Admission Only
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.
