The History of Mensa

The Founding: Oxford, England (1946)

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 Early Years

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.

Mensa's Three Purposes

• Identify and foster human intelligence for the benefit of humanity.
• Encourage research into the nature, characteristics, and uses of intelligence.
• Provide an intellectual and social environment for members.

Baton Rouge's Connection to Mensa

Baton Rouge Mensa is an American Mensa local group in Region 6. Its published territory spans much of southern Louisiana and includes activity in Baton Rouge, Lafayette, Lake Charles, and Hammond. Current officers, testing sessions, venues, and event calendars should be verified through the official chapter and American Mensa pages.

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.

Baton Rouge Mensa

The local group serves a broad southern-Louisiana territory and is part of American Mensa’s Southwest Region. Public chapter pages list local officers and a testing coordinator, but they do not provide a reliable current count of members living inside Baton Rouge city limits.

Who Takes the Mensa Test in Baton Rouge?

Adults and older teens may pursue qualification for community, personal curiosity, or gifted-peer connection. Children generally qualify through accepted prior evidence rather than the standard adult admission test, subject to current American Mensa rules.

Activities and Resources

Members may use local gatherings, regional events, newsletters, online groups, gifted-youth resources, scholarships, special-interest groups, and American Mensa national programs. Membership does not replace an educational, clinical, career, disability, or neuropsychological evaluation.

Accepted Tests for Mensa Qualification

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.

• Reynolds Intellectual Assessment Scales – IQ 130
• Differential Ability Scales (DAS) – GCA 130-132

Tests Administered by Schools

The Mensa Testing Process

Two Ways to Qualify

1. Take an American Mensa admission test: Use a currently scheduled, supervised session or approved private-testing option.
2. Submit prior evidence: Send documentation from an accepted test showing performance at or above the 98th percentile.

The Mensa Admission Test

Availability in Baton Rouge changes. Use the official American Mensa testing calendar or Baton Rouge Mensa contact information rather than assuming a psychology office administers the Mensa-owned admission test.

What the Mensa Admission Test Measures

The admission process is designed only to determine whether the applicant reaches the qualifying percentile. It is not a clinical diagnostic battery and generally does not provide the detailed index scores, educational recommendations, or medical interpretation of a psychologist-administered evaluation.

Important: The Test is for Admission Only

For ADHD, learning disability, autism, brain injury, cognitive decline, accommodations, gifted education, or career guidance, choose an appropriately broad evaluation instead of relying on a Mensa result.

Prior-Evidence and Privacy Checklist

• Confirm the exact accepted test edition and qualifying score.
• Ask whether a sealed report, school record, or psychologist verification is required.
• Submit only the necessary documentation and review privacy terms.
• Do not practice secure IQ-test items or retest at short intervals simply to chase a score.

Baton Rouge Mensa Qualification Planning

PTI (Post Trauma Institute of Louisiana) in Baton Rouge explicitly advertises IQ and cognitive assessment, but applicants should confirm that the proposed instrument and report satisfy current American Mensa prior-evidence rules before scheduling. The office’s testing service is separate from Baton Rouge Mensa and American Mensa.
