IQ test for 13-year-olds
A free picture-puzzle IQ test made for 13-year-olds. It has 12 puzzles, takes about 12 minutes and compares your child only with other 13-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 13
At thirteen, reasoning with abstract rules grows fast. Two tests a year apart can show that growth clearly.
School tests at this age
Around 10 to 11 children in the UK sit the 11+, and CAT4 is common at the start of secondary school in UK and international schools.
What is a good IQ for a 13-year-old?
For a 13-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 13 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 |

Questions
How long does the test take for a 13-year-old?
About 12 minutes for 12 puzzles. There is one time limit for the whole test; speed does not change the score.
Can my 13-year-old take it alone?
Yes. Most children this age take it alone, and many like to compare with friends later.
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.
