Why AurorIQ
Built differently, by design
Most free IQ tests inflate your score to make you feel good and share results. We built AurorIQ to do the opposite.
IRT scoring model
Item Response Theory — the same statistical framework used in the WAIS-IV and SAT. Your score reflects question difficulty, not just how many you answered correctly.
Zero data collection
All scoring runs entirely in your browser. No data is sent to our servers. No account, no email, no tracking — your results exist only on your device.
Honest limitations
We publish our confidence intervals, known biases, and what the test cannot measure. No online test is a clinical assessment — we say so, plainly.
Real norm group
Percentiles calculated against 50,000+ real test-takers — not a theoretical distribution. When we say 87th percentile, we mean 87th percentile.
5 cognitive domains
Pattern recognition, numerical reasoning, verbal intelligence, spatial reasoning, and working memory — each scored separately so you understand your profile.
The AurorIQ Promise
“If your score is lower than you expected, that’s probably because other tests were inflating it. We’d rather be accurate than popular.”

The Process
How the test works
Three steps from start to your honest, calibrated score.
Answer 25 adaptive questions
Each question is chosen in real time based on your previous answer. The test spans all 5 cognitive domains and continuously refines its estimate of your ability level.
~15 minutesIRT scoring runs locally
When you finish, the 2-Parameter Logistic IRT model calculates your theta estimate, converts it to an IQ score, and maps it against the norm group — all in your browser.

By design: IQ is standardised so that the mean is always 100 and the
standard deviation is always 15. Exactly 50% of the population scores between 90 and 110.

What people say
Honest test, honest reactions
Not everyone loves a calibrated score. But they trust it.
★★★★★
“I’d done four other free IQ tests before AurorIQ. They all gave me 130+. AurorIQ gave me 112. I looked into the methodology and AurorIQ is clearly the one doing it right. My ego didn’t love it, but my brain did.”
IQ 112 · High Average · 79th percentile
★★★★★
“The domain breakdown is what sets this apart. Seeing that my pattern recognition was 94th percentile but verbal was 61st actually told me something useful. Other tests just hand you a number.”
★★★★★
“Finally a test that acknowledges its own limitations. The results page says ‘this is not a clinical assessment’ instead of pretending otherwise. That alone makes it trustworthy.”
