Compare the admission test with prior evidence
American Mensa accepts qualifying performance in the top 2% through a supervised admission test or accepted prior evidence.
| Route | Best for | Cost and typical processing | Main trade-off |
|---|---|---|---|
| Local Group admission test | Qualification at the lower test fee | USD 60; commonly 2–3 weeks | Session availability and travel |
| Private Testing | Easier scheduling and a faster result | USD 99; commonly 2–3 business days | Higher fee and test-center availability |
| Prior evidence | Someone who already has an accepted professionally administered score | Currently free; usually 2–4 weeks; assessment and document costs are separate | Exact test, edition, composite, score, and document requirements |
If membership is the only goal, the admission test is the direct route. If an accepted score already exists, prior evidence avoids another test. Arrange a full WAIS evaluation only when its IQ value, cognitive profile, and professional interpretation are useful beyond Mensa.
All three routes return a qualification decision. The admission routes do not provide a detailed IQ report, and prior-evidence review does not produce a new IQ result.
The US admission test is broad and highly speeded
The admission test is a multi-section battery mixing verbal, numerical, memory, and visual reasoning under strong time pressure. It is not a matrix-only test.
To use this route, choose Local Group Testing or Private Testing on the American Mensa testing page, register and pay, complete the supervised battery, and wait for the qualification decision. Local Group Testing costs less; Private Testing is the faster, more flexible route.
Useful preparation means becoming comfortable with timed switching among different question formats. American Mensa uses the battery to decide qualification and no longer supplies a detailed IQ score report.
The official Mensa Practice Test and third-party online IQ tests cannot be used as admission evidence.
Prior evidence can qualify you without another admission test
A WAIS result can be submitted as prior evidence when its score and report meet American Mensa's requirements.
Start with the current accepted-score rules. Confirm that your exact WAIS edition, composite, and score are accepted, then check that the administration and report meet the documentation rules. Submit the original score record or a notarized copy, or have the school or testing agency send the record directly, as the rules require. Prior-evidence review usually takes two to four weeks.
A WAIS report can provide FSIQ, domain and subtest scores, confidence intervals, and professional interpretation. That broader information—not Mensa qualification alone—is the reason to arrange a new assessment. The US WAIS guide explains how to obtain one, while WAIS and online IQ tests compared separates their uses and results.
Retesting requires an eight-week wait and another available test
Admission testing is available from age 14; younger applicants use suitable prior evidence.
If you do not qualify, wait eight weeks before taking another available admission test or battery. After exhausting those options, prior evidence is the remaining route. Once a testing purchase has been processed, the fee is non-refundable.
Qualification lasts for life. Active membership requires dues, currently USD 107 for one year.
