What's inside the test

Number and letter sequences, matrix patterns, verbal analogies, spatial rotation — 40 tasks across four categories, calibrated so the average lands near IQ 100. Results are preliminary-calibrated until 500 completions; the percentile line updates as more people take it.

Why "verifiable" matters

Every other online IQ test gives you an image anyone can edit in Paint. A VerIQ link re-checks the signature server-side on every view — if it says valid, the score was issued by VerIQ and never altered. Read how verification works.
