Science-based IQ testing, free for everyone
MyIQTested exists to make reliable cognitive assessment accessible to everyone. We believe that understanding your cognitive strengths shouldn't require expensive clinical visits or questionable online tools that gate results behind paywalls.
Our test is built on the International Cognitive Ability Resource (ICAR), a peer-reviewed, open-source assessment framework developed at Northwestern University. Every question has been validated in published research, and our scoring methodology follows established psychometric standards.
The ICAR was developed by David Condon and William Revelle as a free alternative to proprietary IQ tests. Published in the journal Intelligence in 2014, the ICAR includes four types of reasoning tasks: matrix reasoning (visual pattern completion), letter and number series (sequential logic), verbal reasoning (word relationships), and three-dimensional rotation (spatial ability).
In validation studies, ICAR scores correlate strongly with established measures like Raven's Progressive Matrices (r = .60-.80) and the Shipley Institute of Living Scale (r = .81), demonstrating that open-source assessment can match the quality of proprietary instruments.
Online IQ tests, including ours, are educational tools — not clinical assessments. A proper IQ evaluation requires a trained psychologist, controlled conditions, and a comprehensive battery of subtests. Our test provides an informed estimate, but factors like test anxiety, distractions, and screen familiarity can shift scores by 5-10 points.
If you need an IQ score for clinical, educational, or legal purposes, please consult a licensed psychologist who can administer standardized instruments like the WAIS-IV or Stanford-Binet.
