An IQ score of 110 falls into the High Average range on the standard intelligence scale (mean = 100, standard deviation = 15). This score is above the population average — about one in four people scores at this level or higher.
Where does an IQ of 110 rank?
On a standardized IQ test, a score of 110 places you higher than approximately 74.8% of the population. Intelligence scores follow a normal distribution — most people cluster near 100, and scores taper off sharply toward both extremes.
| Metric | Value |
|---|---|
| IQ score | 110 |
| Classification | High Average |
| Percentile | 74.8% |
| Rarity (out of 1,000) | ~252 in 1,000 score this high or higher |
| Standard deviations from mean | 0.67 |
Which IQ tests produce a score of 110?
A score of 110 can be produced by any standardized intelligence test that uses the mean = 100, SD = 15 scale. The most widely used tests include:
- Wechsler Adult Intelligence Scale (WAIS) — clinical gold standard for adults.
- Stanford-Binet Intelligence Scales — oldest continuously-used intelligence test.
- Mensa admissions test — used by the Mensa society for membership selection.
- Cattell-Horn-Carroll (CHC) tests — most theoretically grounded modern framework.

How to interpret an IQ score of 110
Scores in the high-average to superior range are associated with strong performance in educational and analytical settings. People at this level often report that unstructured problem-solving and abstract learning feel relatively natural, though domain expertise still requires deliberate practice.

Factors That Influence Your Score
Your IQ score reflects a combination of genetic potential and environmental influences including education, nutrition, health, and the testing conditions themselves. Factors like fatigue, anxiety, unfamiliarity with the test format, and even the time of day can all affect performance. A single test score should be viewed as an estimate, and scores can vary by several points between testing sessions.

Compare the major IQ tests
Which test produces the most accurate score depends on what you're trying to measure. These head-to-head comparisons break down the differences:
- WAIS vs Stanford-Binet — the two clinical heavyweights compared.
- Mensa vs WAIS — entry-test speed vs full clinical assessment.
- Stanford-Binet vs Mensa — which one actually gets you into Mensa.
- CHC vs Wechsler — modern cognitive framework vs the classic.
- Raven vs Cattell — non-verbal alternatives for cross-cultural testing.

Is IQ 110 considered good?
An IQ of 110 is within the average range — where most of the population scores. "Good" depends on context: IQ is one factor among many that contribute to life outcomes.
Can an IQ of 110 change over time?
IQ scores are relatively stable in adulthood but can shift modestly with education, engagement, sleep, and health. Short-term factors like stress and fatigue can move a single test result by 5–10 points in either direction — which is why we recommend comparing results across multiple sessions rather than reading too much into any single score.
What percentile is IQ 110?
An IQ of 110 corresponds to the 74.8th percentile on the standard bell curve — meaning it is higher than about 75 out of every 100 people.
