IQTests is an independent project, not a clinic and not a recruiter. We build one thing well: a free reasoning test that gives you an honest estimate of how you score on a set of well-studied problem types, then tells you what that number does and doesn’t mean.
There is no upsell here to a “certified” score, no membership to join, and no forty-page report waiting behind a card form. You answer the questions, you get a result, and you can read exactly how it was produced.
Where the test comes from
The questions are modelled on the International Cognitive Ability Resource (ICAR), a public-domain item set assembled by David Condon and William Revelle and published in the journal Intelligence in 2014. We chose an established pool over a homemade question bank for one reason: ICAR items have been given to large samples and checked against full-length instruments, so the problem types carry real measurement evidence rather than a designer’s hunch.
How those answers become a score, how we place it on the 100-point scale, and where the limits sit are all written up on our methodology page. We would rather you read how the result is made than take it on faith.
What we are not
We are not psychologists, and a ten-minute online test is not a clinical assessment. A supervised Wechsler (WAIS-IV) or Stanford–Binet session, run by a licensed examiner over a couple of hours, measures more and measures it more reliably. If you need a score for a diagnosis, a school placement, or anything with real stakes, that is the route to take — and we say so on every result page and in our terms of use.
Why we built it
Most “free IQ test” results online fall into two camps: flattering nonsense designed to sell a certificate, or a bare number with no context at all. People deserve the path between those — a score grounded in real item research, paired with a straight word about confidence intervals, the Flynn effect, and the plain fact that a tired afternoon can cost you ten points. That is the whole idea, and the methodology backs every part of it.
Our stance on your data is simple. We don’t run advertising trackers, we don’t sell information, and the test is scored in your browser. The specifics of what we collect and how to remove it live in our privacy policy, and the small files the test saves on your device are listed in the cookie policy.
The same instinct drives everything else we publish: the guides explain how cognitive testing actually works, and the blog exists mostly to take apart IQ numbers that were never measured by anyone. If you spot a question you think is wrong, or you just want to disagree with one, our contact page reaches a real person. And if you have not yet, the best way to understand any of this is to take the free test — it runs in about ten minutes and ends with a full breakdown across four reasoning domains.
