Built on the four-domain cognitive model and the standard 100-average scale used by established IQ tests.
What is an IQ test?
An IQ test is a standardized assessment that measures human intelligence relative to the general population. Scores are placed on a scale with an average (mean) of 100 and a standard deviation of 15, so a score of 100 is exactly average and about two thirds of people score between 85 and 115.
Rather than measuring how much you know, an IQ test measures reasoning ability: how well you identify patterns, solve novel problems, reason with words and numbers, and hold information in mind. Most modern tests report a single composite IQ score plus subscores for the specific cognitive domains they assess.
Key facts about IQ tests
- The average IQ score is 100 by design, on a scale with a standard deviation of 15.
- About 68% of people score between 85 and 115, and about 95% between 70 and 130.
- IQ measures reasoning and problem-solving ability, not knowledge, effort, or character.
- A single online score carries measurement error of roughly 5 to 10 points, so it is best read as a range.
- Online tests give an educational estimate; a clinical diagnosis requires a licensed psychologist.
This free IQ test measures four cognitive domains and reports your composite score with a percentile and a breakdown of your strengths. It is designed for education and self-insight, not clinical diagnosis.
Cognitive Domains Tested
Comprehensive assessment across multiple cognitive areas
Logical Reasoning
Spot the rule behind a sequence or pattern and apply it. Tests fluid reasoning - your ability to solve novel problems without relying on prior knowledge.
Spatial Intelligence
Rotate, fold, and compare shapes in your mind. Measures visual-spatial ability, the skill that underpins engineering, geometry, and navigation.
Verbal Comprehension
Work with analogies, relationships, and meaning in language. Reflects crystallised verbal ability - how well you reason with words and concepts.
Working Memory
Hold and manipulate several pieces of information at once. The mental workspace that supports reasoning, comprehension, and learning.

What is a good IQ score?
On the standard scale (mean 100, standard deviation 15), 90 to 109 is average, 110 to 119 is high average, 120 to 129 is superior, and 130 or above is in the gifted range (top 2%). A score of 100 is exactly average, so anything above 100 is above average.
How do IQ tests work?
An IQ test presents reasoning problems across domains such as logical, verbal, numerical, and spatial reasoning. Your raw answers are compared against a large standardization sample and converted to a standard score, where 100 is the population average and every 15 points represents one standard deviation from that average.
Are online IQ tests accurate?
A well-designed online IQ test gives a reasonable educational estimate, typically within about 5 to 10 points of a supervised result, as long as you take it rested and without distractions. It is not a substitute for a clinical assessment by a licensed psychologist, which is required for any formal diagnosis.
What is the average IQ?
The average IQ is 100. The scale is built so that the mean is always 100 and the standard deviation is 15, which means roughly half of people score above 100 and half below, and about two thirds score between 85 and 115.
