What does an IQ of 115 mean?
- 115 is exactly 1 standard deviation above the average of 100.
- In a group of 100 people, about 16 would score higher than 115.
Scores from 110 to 119 are High Average, the step above the middle of the scale. About 16% of people score here.
People in this range usually pick up new material without much trouble and do well with problems that require reasoning. It is above most people, but still close enough to the middle that effort, knowledge and interest matter more than the difference between, say, 112 and 118.
Because of measurement error, scores just above 110 and just below 110 are practically the same result. Read the band as a range, not a hard line.
IQ 115 on other scales and tests
Different tests spread scores differently. The same rank as an IQ of 115 on an SD-15 test gives these numbers elsewhere:
| Scale | Equivalent score | Classification |
|---|---|---|
| SD 15: WISC-V, WAIS, Stanford-Binet 5 | 115 | High Average |
| WAIS-IV (older label) | 115 | High Average |
| Stanford-Binet 5 | 115 | High average |
| SD 16: older Stanford-Binet, Cattell Culture Fair | 116 | – |
| SD 24: Cattell III B | 124 | – |
How precise is an IQ score of 115?
No test measures IQ exactly. On individually administered tests such as the WAIS, the full-scale score comes with a 95% confidence interval of roughly ±5 points, so a result of 115 is best read as "probably somewhere between 110 and 120". Scores can also shift a few points between different tests or after a few years.
Online tests, including ours, are self-assessments. They are useful for curiosity and practice, but they are not a substitute for an assessment by a psychologist.
