About
IQ testing that doesn't waste your time
IQScore exists because most online IQ tests are broken. They make you sit through ads, ask for your email, charge you to see your results, or give you a vanity score designed to make you feel good rather than measure anything real.
Who built this
AJ Dorey
Founder, IQScore
AJ Dorey is an English software developer who researches and writes about intelligence and cognition. He built IQScore because most online IQ tests are broken. Most sites either inflate scores to keep people happy or bury the results behind a paywall after you've already spent 20 minutes answering questions.
The idea was to build something honest and calibrated. If the results are free, they should stay free. AJ writes every article on this site with the same standard: cite the research, be honest about what the data shows, and never oversell what a single 25-minute test score actually means.
What IQScore does differently
Free. Always.
The core IQ test, 36 questions, full scoring, instant results, is completely free. No sign-up, no email, no credit card. We believe access to cognitive assessment should not depend on ability to pay.
Built to be honest, not flattering.
Many online IQ tests inflate scores to make users feel good and share them. IQScore maps your performance onto the standard IQ scale (mean 100, standard deviation 15) and is upfront that it is an estimate with a real margin of error, not a vanity number.
Four cognitive domains, not one number.
Your results break down spatial reasoning, numerical reasoning, logical reasoning, and applied reasoning separately. A single number tells you where you rank; a domain breakdown tells you what your actual cognitive profile looks like.
Research-backed articles.
The IQScore Learn blog covers IQ science, cognitive performance, and brain health without pop-science shortcuts. Every article cites primary research and distinguishes between what the evidence actually supports and what is marketing.
The test methodology
The IQScore assessment consists of 36 questions across four cognitive domains, weighted by difficulty. Your performance is mapped onto the standard IQ scale, mean 100, standard deviation 15, and expressed as an estimated score and percentile. It is a screening estimate, not a population-normed clinical instrument.
The test measures general cognitive ability (g) through tasks assessing pattern recognition, logical inference, numerical reasoning, and spatial reasoning. These domains are consistent with the CHC (Cattell-Horn-Carroll) model of cognitive abilities that underlies most modern professional intelligence assessments.
IQScore is an online screening assessment. Like all online IQ tests, it provides an estimate of cognitive ability rather than a clinically validated diagnostic score. For clinical or educational assessment purposes, a professionally administered test (WAIS-V, Stanford-Binet 5, or equivalent) conducted by a licensed psychologist is the appropriate standard.
The optional paid extras
The free test and results are complete on their own, no strings attached. For those who want to go deeper there is exactly one thing to buy: the IQScore Pack, $6.99, paid once. It contains a personalised certificate with your name, score and percentile as a print-ready PDF, a full written analysis of your cognitive profile with your strengths, your development areas and ways to raise your score, and every one of the 36 questions explained with the correct answer. That is the entire shop. There is nothing to buy afterwards, it is never required, and the free results never expire.
That's it. No subscription, no upsell emails, no account needed.
