Enter your age — we use it to select the assessment variant and modelled age-banded scoring table. No signup, no subscription, no credit card required.
IQ Test Center measures five cognitive areas instead of relying on one short puzzle type. Enter your age and complete 30 timed questions. Your overall result band is shown when you finish; the detailed educational report is a one-time unlock and includes a modelled score estimate, indicative percentile context, and a five-domain profile.
Your score uses a modelled age-banded conversion table rather than one generic adult table.
Verbal, logical, quantitative, visual-spatial, and working-memory questions are scored separately.
See your overall result band when you finish, then unlock the educational score estimate, indicative percentile, timing metrics, and domain profile.
The assessment itself is free and needs no signup — enter your age and begin. When you finish you see your overall result band free of charge; unlocking the full report (educational score estimate, indicative percentile, five-domain breakdown and print-ready PDF) is a one-time $1.99 payment. There is no subscription, and an account is optional — it saves a result but does not unlock it.
Yes. Your educational score estimate, indicative percentile, and 5-domain cognitive profile are calculated when you complete the 30 questions — there is no waiting period and nothing is mailed to you.
It means the site selects a modelled score-conversion table for your age band rather than one generic adult table. These tables are transparent educational approximations, not norms calibrated on a representative population sample.
Most people finish in about 25 minutes. The adult version has 30 questions on a server-controlled 25-minute timer, so plan an uninterrupted block of time before you start.
