The History of Mensa
The Founding: Oxford, England (1946)
Mensa was founded in England in 1946 by Roland Berrill and Dr. Lancelot Ware. Its 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.

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
American Mensa offers local-group test sessions and private testing at approved facilities. Availability near Chattanooga depends on Chattanooga Mensa and national scheduling systems.
- Duration: Commonly one to two hours total, depending on the session and current procedures.
- Format: Supervised standardized testing under American Mensa rules.
- Qualifying: A qualifying result indicates performance at or above the 98th percentile.
- Cost: Use current official pricing rather than old local advertisements.
- Location: Sessions may be elsewhere in the Chattanooga metro, so verify address, parking, accessibility, and travel time.
- Preparation: Sleep, hydration, heat exposure, medication, illness, and recent practice can affect performance.
What the Mensa Admission Test Measures
- Pattern recognition – Identifying sequences and relationships
- Logical reasoning – Deductive and inductive thinking
- Spatial visualization – Mental manipulation of objects
- 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.
Prior-Evidence and Privacy Checklist
- Verify the test and edition on American Mensa’s current accepted list.
- Ask whether the required composite or index—not merely a subtest—will be reported.
- Confirm examiner credentials and supervised standardized administration.
- Request original or officially certified documentation with date, scores, and identifying information.
- Understand what clinical information will appear in the report and what must be submitted.
- Do not assume an online quiz, school percentile, or population estimate qualifies.
Chattanooga Mensa Qualification Planning
- Check the current American Mensa accepted-test and prior-evidence pages before scheduling private testing.
- Ask the evaluator whether the exact edition and score will be reported in a form Mensa can verify.
- Do not assume every index, abbreviated score, school screening, online test, or private report is accepted.
- Consider whether the evaluation should also answer educational, clinical, disability, or career questions.
- Use official Chattanooga Mensa and American Mensa calendars for current local testing and event information.
