Compare supervised testing with prior evidence
Both routes use the 98th-percentile threshold—the top 2%.
| Route | Best use | Access | Result supplied | Main trade-off |
|---|---|---|---|---|
| Scheduled regional test session | Direct membership qualification | Active session and its regional booking officer; age 16+ | Qualification outcome; individual scores are not released | Event availability and travel |
| Prior evidence | An existing adult professional result or an applicant under 16 | Formal result from a registered psychologist, submitted for review | Decision after accepted-test and document review | Professional assessment and documentation requirements |
If membership is the only goal, use a regional session. If an adult already has a professional result to submit, or the applicant is under 16, use prior evidence.
Mensa South Africa operates regional sessions in areas including Cape Town, Johannesburg, KwaZulu-Natal, Pretoria, and the Winelands.
The session uses both a visual test and a verbal mental-alertness test
The session uses two tests with different demands: the visual, nonverbal FRT-A and the South African Mental Alertness test, which places more weight on verbal and local-language knowledge. A qualifying performance on either can be sufficient.
Prepare for fast, accurate work across both the visual and verbal formats.
Prior evidence uses a result from a registered psychologist
Applicants under 16 use this route because Mensa-administered sessions begin at age 16. Adults who already hold a professional result can use the same review route instead of sitting a new regional test.
The registered psychologist's formal result is submitted through Mensa South Africa and reviewed against the top-2% admission standard. Individual scores are not released from the regional Mensa session, whereas a professional assessment supplies the documented score needed for prior evidence.
If membership is the only goal, the regional Mensa session is the simpler route. WAIS is worth arranging when the overall IQ result, domain scores, and professional interpretation are also useful; an existing professional report can then be submitted as prior evidence. Compare professional WAIS and online testing, then use the South African WAIS guide for the local edition and norm fit.
Regional sessions are booked through the active schedule
The active regional schedule lists sessions for Cape Town, Johannesburg, KwaZulu-Natal, Pretoria, and the Winelands. Bookings are made through the testing officer shown for each region.
At some recent sessions, candidates received pass/fail within roughly 30–60 minutes.
