IQ test

Choose 18–80 varied tasks covering verbal, numerical, logical and spatial reasoning, as well as attention. Task types alternate regularly.

Before you begin

  • This informal test is not a substitute for a standardised assessment by a psychologist.
  • Age is required because the approximate result takes the age group into account.
  • The question bank contains 212 questions. The next test in the same session will not reuse questions from the previous test.
  • The questions are text only, keyboard accessible and designed for screen readers.
  • Speed alone does not improve your score. When the chosen time runs out, the question is recorded as unanswered.
  • Your progress is saved only in the current browser session, not in the database.
Participant age

Your age is used only for the age-adjusted estimate and stays in the current browser session.

Number of questions

A shorter test is quicker; a longer test gives a slightly more stable estimate.

Time per answer

Screen reader users may prefer the default three minutes. If you need more time to reread, choose five minutes or no time limit.
