A method you can inspect
Every issued result records its test and score-model version. Our provisional limits are public.
Your report is not a public profile
Private results are non-indexable. The share action promotes the public test page, never your answers or score.

A complete learning artifact—still free and private
Preview the certificate, domain interpretation and explanation format before you begin. After your result, share or copy the public test link to unlock it.

Know what this test can—and cannot—tell you
Is this IQ test really free?
Yes. Your score estimate, percentile and four-domain summary are always free. Sharing or copying IQTestHQ also unlocks the certificate, full report and 36 explanations.
Do I need an account, email or payment?
No. The test, result and share-unlocked report work without an account, email or payment.
How accurate is the score?
It is a provisional online reasoning estimate, not a supervised clinical score. Treat it as a range with expected uncertainty of about ±10 points.
Can I pause the timer?
No. Once confirmed, the test has one 25-minute clock. Your saved progress can recover from a refresh, but the clock continues.
What happens if time runs out?
Your saved answers are submitted automatically. Unanswered questions count as incorrect.
Can I retake it?
Yes, but practice effects can raise retest scores. Only eligible first attempts are used for future calibration.
