About Us

Last updated: October 31, 2026

IQ Test Online is operated by Cognitive Lab. We build a short, honest online reasoning test and tell you exactly what it can and cannot measure.

The test

• 20 pattern-reasoning questions, 30-minute limit
• No account and no email address required
• Works on desktop and mobile, in 11 languages

How scoring works

Each question's difficulty comes from how often real test-takers answer it correctly, not from a number we picked. Your raw result is placed on the standard IQ scale (mean 100, standard deviation 15) and shown with your percentile.

What it is not

This is not a clinical or diagnostic assessment and is not equivalent to a professionally administered test such as the WAIS. Use it for curiosity and self-reflection, not for admissions, hiring or medical decisions.

Pricing

Taking the test is free. The detailed score report is a one-time payment of $7.99 through PayPal. There is no subscription and no recurring charge. See our Refund Policy.
