What does an IQ of 110 mean?

110 is the lowest score in the High Average range (110–119).
In a group of 100 people, about 25 would score higher than 110.

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 110 on other scales and tests

Different tests spread scores differently. The same rank as an IQ of 110 on an SD-15 test gives these numbers elsewhere:

Scale	Equivalent score	Classification
SD 15: WISC-V, WAIS, Stanford-Binet 5	110	High Average
WAIS-IV (older label)	110	High Average
Stanford-Binet 5	110	High average
SD 16: older Stanford-Binet, Cattell Culture Fair	111	–
SD 24: Cattell III B	116	–

How precise is an IQ score of 110?

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 110 is best read as "probably somewhere between 105 and 115". 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.
