Fourteen is a common age to get curious about IQ. School starts sorting people into sets, exam options come up, and online IQ scores are everywhere.

Here is what a 14 year old should know before taking this test, and what the result can and cannot tell you.

How this test works for 14 year olds

The scoring is the same for everyone and is not age-adjusted. At 14 your reasoning is still developing, so expect to get fewer questions right than you will in a few years. A result here is best compared with your own future attempts, not with an adult's number.

The five question types each start easy and get harder. It is normal to find the last one or two in each set very tough.

What IQ scores mean at 14

On a normed test, a 14 year old is compared with other 14 year olds. The table shows what share of them each score beats. These are the standard figures for any IQ scale with an average of 100 and a standard deviation of 15.

IQ	Higher than	How rare
IQ 100	50.0% of people	Common
IQ 110	74.8% of people	about 1 in 4 this high
IQ 115	84.1% of people	about 1 in 6 this high
IQ 120	90.9% of people	about 1 in 11 this high
IQ 130	97.7% of people	about 1 in 44 this high
IQ 145	99.87% of people	about 1 in 741 this high

Computed from the normal curve (mean 100, standard deviation 15). Applies to properly normed tests.

Can a 14 year old's IQ change?

Yes, more than most people think. In a University College London study published in Nature in 2011, teenagers first tested between 12 and 16 were retested about four years later. Some moved up or down by as much as 20 points. The group average barely moved, but individuals did.

That is a good reason not to let one number at 14 decide what you think you can do.

Tests a 14 year old might meet at school

None of these give an IQ score, and nothing you score here is shared with a school.

CAT4 (UK): many secondary schools use this reasoning test to set expectations. Its non-verbal and spatial sections look a lot like these puzzles.
PSAT 8/9 (US): a College Board test for 8th and 9th graders, focused on reading, writing and maths rather than IQ.
