Mensa IQ Test

Built in the style used for high range screening, weighted towards harder items than a general ability test.

What it measures

A timed set in the style used by high-IQ society entrance tests. It is not affiliated with Mensa and does not qualify you for membership anywhere.

Your score is read against adults generally. The bands below come from the shape of a normal distribution, which is the model the scoring assumes rather than a count from a reference sample. Most people sit in the middle and both ends are rare by definition, so a band is a position in a distribution, not a verdict.

Good uses

  • Seeing what that style of test feels like under a clock.
  • Seeing where you sit relative to adults generally.
  • Comparing your result against the other forms on this site.

Known limits

  • An unsupervised online test is not a clinical assessment and is not an IQ certificate.
  • It carries no official standing and cannot be submitted anywhere.
  • Tiredness, interruptions and previous practice all move the score.
