An IQ score of 115 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.
What an IQ of 115 means
115 is one standard deviation above the mean, the counterpart of 85 on the other side. About 84% of people score lower, so roughly one in six scores at this level or higher. It is in the high-average band. 115 is the score at which many people first notice that they tend to grasp explanations quickly or enjoy puzzles that others find tedious. It is also a level where test anxiety, unfamiliar formats or a slow device can hide a few points, which is worth remembering if you expected to score higher. As a single number, 115 indicates clearly above-average reasoning on the tasks the test measured.
Where does an IQ of 115 rank?
On a standardized IQ test, a score of 115 places you higher than approximately 84.1% 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 | 115 |
| Classification | High Average |
| Percentile | 84.1% |
| Rarity (out of 1,000) | ~159 in 1,000 score this high or higher |
| Standard deviations from mean | 1.00 |
IQ 115 in numbers
- Roughly 1 in 6 people score 115 or higher.
- In a room of 100 randomly chosen adults, about 16 would score 115 or higher.
- That is 15 points below 130, the level most high-IQ societies use as their entry line.
- Another 5 points would move this score into the Superior band, which starts at 120.
- Even on professionally administered tests a single result has a margin of error of about five points either way, so a measured 115 is best read as somewhere between 110 and 120.
On our free IQ test
Of the 3,834 people who completed our free IQ test between April and October 2026, 139 scored exactly 115 and 48.1% scored higher. People who choose to take an online IQ test are not a random sample of the population (our average is 114.5), so this shows where a score sits among other test-takers, not among everyone.

Which IQ tests produce a score of 115?
A score of 115 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.
- Our free IQ test — instant online estimate with the same scaling.
How to interpret an IQ score of 115
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 115 considered good?
An IQ of 115 is above average (84th percentile). It's associated with strong academic and analytical performance, though IQ is only one dimension of overall ability.
Can an IQ of 115 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 115?
An IQ of 115 corresponds to the 84.1th percentile on the standard bell curve — meaning it is higher than about 84 out of every 100 people.
