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

Macon-Bibb County, Georgia and Mensa

American Mensa does not publish a verified membership count for Macon-Bibb County, and there is no special city-specific admission standard. Residents can use Mensa’s current testing options or submit acceptable prior evidence under the national organization’s rules.

Macon-Bibb County residents may participate in activities offered by the applicable regional Mensa group, online communities, or events elsewhere in the Middle Georgia regionpolitan region. Meeting schedules and boundaries change, so use American Mensa’s official group directory rather than relying on an old local listing.

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.

Mensa in Macon-Bibb County

Macon-Bibb County residents interested in American Mensa should use the organization’s official locator, testing calendar, and prior-evidence rules to identify current Middle Georgia or regional options. Local event locations and testing schedules can change, and no reliable public count identifies the number of members living within the consolidated city-county.

Applicants may qualify through a supervised Mensa admission test or accepted prior evidence. Before paying for private testing, confirm the exact accepted test, edition, score, percentile, administration conditions, examiner credentials, and original-report requirements. A psychologist may provide a clinically useful cognitive evaluation, but Mensa alone determines whether the evidence qualifies.

Because accepted evidence and local testing opportunities may change, applicants should retain original score reports and verify requirements directly before scheduling or submitting documents.

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.

The Mensa Testing Process

Two Ways to Qualify

There are two primary pathways to Mensa membership:

1. Take the Mensa Admission Test: A supervised test administered by Mensa proctors
2. 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

American Mensa offers local-group testing when sessions are scheduled and private testing through its current testing network. Macon-Bibb County-area availability changes, so search by ZIP code on the official testing page. Key details:

• Duration: 1-2 hours total
• Format: Two separate timed tests (the Wonderlic and Culture Fair tests)
• Qualifying: You only need to qualify on one of the two tests
• Cost: Approximately $40 for the test

• Problem-solving – Complex reasoning under time pressure

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.
