What is a Good IQ Score for Every Age?

What is an intelligent type test?

IQ scores are usually measured on a scale with a mean of 100 and a standard deviation of 15. It’s important to note that different free IQ tests will yield different results and you should not think that the IQ score will reflect your abilities, as it doesn’t capture the full range of human intelligence or potential.

Here are the typical IQ scores by age:

Age RangeAverage IQ Score
16 – 17108
18 – 19105
20 – 2499
24 – 3497
35 – 44101
45 – 54106
> 65114
