Our Mission

Intelligence, Measured Fairly — For Everyone.

Regardless of where you live, what language you speak, or what resources you have access to — you deserve a reliable, scientifically grounded way to measure and understand your intelligence.

What is IQ (intelligence quotient)?

IQ (intelligence quotient) is a standardized measure of cognitive ability derived from psychometric testing. It evaluates how effectively a person reasons, solves problems, identifies patterns, and processes information compared to the general population. IQ scores are normalized so that the population average is 100, with a standard deviation of 15. Score ranges indicate performance levels: 90–109 (Average), 110–119 (High Average), 120–129 (Superior), 130+ (Very Superior).

110–119 High Average
