IQ test for 15-year-olds
A free picture-puzzle IQ test made for 15-year-olds. It has 12 puzzles, takes about 12 minutes and compares your child only with other 15-year-olds. An IQ of 100 is the middle for this age; 110 to 119 is above average and 130 or more is very high. No name or email is needed.
What to expect at 15
At fifteen scores are close to adult levels. The test still compares only with fifteen-year-olds, so the number stays fair.
School tests at this age
CAT4 higher levels are used in some secondary schools. From 16, the adult levels of IQ Atlas are open too.
What is a good IQ for a 15-year-old?
For a 15-year-old, 90 to 109 is average, 110 to 119 is above average, 120 to 129 is high and 130 or more is very high (about 2 children in 100). Because the score is compared within the age, a 100 at age 15 means the same as a 100 at any other age.
| Score | What it means | Children with this score or higher |
|---|---|---|
| 130 and above | Very high | about 2 in 100 |
| 120 to 129 | High | about 9 in 100 |
| 110 to 119 | Above average | about 25 in 100 |
| 90 to 109 | Average | about half of all children score here |
| 80 to 89 | Below average | |
| below 80 | Low for this age, worth a calm talk with the school |

About 12 minutes for 12 puzzles. There is one time limit for the whole test; speed does not change the score.

Yes. Teenagers usually take it alone. From 16 they can also take the adult test.
Is the result a diagnosis?
No. It is an estimate of reasoning with picture puzzles, marked preliminary while our norms grow. For decisions about school, talk to the school or a school psychologist.
