Who we are

Cerebral Assessment is a free, ad-supported non-verbal IQ test made for general interest. There is no sign-up and no account: you pick a test length, work through visual reasoning puzzles, and get a score with a breakdown straight away.

If you want the detail on how the items are built and how the score is calculated, the methodology page covers it. Results are for interest only, not a clinical or diagnostic assessment.
