A high score on an ordinary self-administered website test does not by itself qualify someone for Mensa. Eligibility depends on an accepted assessment and the organization's administration and documentation requirements.
The requirement is about an accepted result
Mensa International describes eligibility in terms of the upper two percent on an approved intelligence test administered under appropriate supervision. American Mensa also specifies requirements for prior evidence and does not accept unsupervised internet tests as proof of eligibility.
Check your national organization's current rules. Procedures, accepted instruments and available supervised formats can differ. A test delivered through a computer is not necessarily the same as an unsupervised quiz.
Why one universal score is misleading
Different tests can use different scales. A number that meets a threshold on one accepted instrument need not mean the same thing on another. A percentile requirement describes a position within a reference distribution; it does not make every score labeled 130 or 132 equivalent.
Avoid deciding from a third-party table alone. Confirm the exact test, edition, required composite and documentation with the organization handling your application.
What starp can and cannot do here
starp offers reasoning practice and a report using its own calibrated scale. It is not a Mensa admissions test, and its score is not evidence of eligibility.
You can use original practice questions to become familiar with solving unfamiliar problems, but do not treat a practice result as a promised outcome on another assessment. The questions, timing and scoring can differ.
Before booking or submitting evidence
Find the official local guidance, check which supervised option or prior evidence is accepted, and follow its preparation instructions. If you already have a professional report, ask whether that exact report is suitable before purchasing another assessment.
These checks save more effort than trying to convert a consumer website score into a formal qualification it was not designed to provide.
