Free IQ Tests — Measure Your Intelligence Online
IQ tests measure cognitive ability across multiple domains: logical reasoning, pattern recognition, spatial thinking, and processing speed. Our free IQ tests are short approximations of formal assessments like the Wechsler Adult Intelligence Scale (WAIS). While they cannot replace a clinically administered IQ test, they provide a reliable directional score based on the same cognitive tasks used by psychologists.

Frequently Asked Questions
What is a good IQ score?
IQ scores are normed to a population average of 100 with a standard deviation of 15. A score of 100–115 is average to above average. Scores above 130 are in the gifted range (top 2%). Scores below 70 may indicate intellectual disability.
Are online IQ tests accurate?
Online IQ tests are directional but not clinically precise. They use the same cognitive task types as formal IQ tests but lack standardised administration conditions. Use your score as a general indicator, not a definitive measurement.
What does IQ actually measure?
IQ tests measure a cluster of cognitive abilities including working memory, processing speed, verbal comprehension, and perceptual reasoning. They correlate with academic performance, occupational success, and learning speed, but do not measure creativity, emotional intelligence, or wisdom.
