Modeled on the WAIS-5
The professional IQ standard
The Wechsler Adult Intelligence Scale is one of the most widely used and respected IQ assessments in professional psychological practice, administered by licensed psychologists. Our free test is inspired by its five major cognitive domains, providing a more structured and comprehensive estimate than a typical single-puzzle IQ quiz. Its professional-style structure is informed by established psychological assessment principles, helping deliver a more meaningful and balanced estimate of cognitive performance.

Most quick online IQ tests use a single question type with no age calibration, which tends to inflate scores. Our free test uses a 5-domain structure modeled on the Wechsler Adult Intelligence Scale (WAIS-5) framework and age-calibrated norms for a more meaningful estimate.
