Online IQ Test: What Your Score Really Means
IQ scores are reported on a scale with a mean of 100 and a standard deviation of 15. About two thirds of people score between 85 and 115.
An online IQ-style reasoning test gives a useful estimate for self-understanding and career exploration, but it is not a clinical assessment.
Key points
- •Practise under timed conditions
- •Review explanations for every mistake
- •Use scores alongside other evidence
Reading the scale
110 to 119 is high average, 120 to 129 superior and 130 or above very superior. Percentiles show the share of a reference population you outperformed.
What affects your score
Sleep, stress, test familiarity and time pressure all influence results. Retaking after practice often changes scores.
Using your report
Look at your strongest reasoning areas and consider roles and courses that use them.
