What is an IQ test, and what does your score mean?
A quick guide to the IQ scale before you start.
What is an IQ test?
An IQ (intelligence quotient) test measures reasoning skills such as spotting patterns, working with numbers, logical deduction, mental rotation and short-term memory. It is not a quiz about school knowledge: it shows how well you solve problems you have not seen before.
How is IQ measured?
IQ scores are placed on a scale where the average IQ is 100 and the standard deviation is 15. About two thirds of people score between 85 and 115, and about 95% between 70 and 130. Your percentile tells you what share of people you scored higher than.
Is an online IQ test the same as a clinical one?
No. Clinical IQ tests such as the WAIS are given one-on-one by a licensed psychologist and are used for diagnosis and school decisions. This online IQ test is a self-assessment: a structured way to test your IQ at home out of curiosity, not a diagnosis.
