What Does a 115 IQ Mean?.
IQ scores are scaled, not counted. The number 115 has meaning only because the scale is built so that 100 is the population average and every 15 points is one standard deviation - the natural spread of human scores. So 115 is not "115 out of something"; it is a position: exactly one step above the middle of the distribution.
A 115 IQ score
On the standard IQ scale (mean 100, standard deviation 15), a score of 115 is exactly one standard deviation above average. It corresponds to roughly the 84th percentile - about 1 person in 6 - and falls at the start of the "above average" range (115 to 129) on the standard bands. It is comfortably above the middle of the distribution but below the conventional "gifted" or Mensa cutoff of 130 (about the 98th percentile). It is a measure of reasoning performance relative to the population, not a fixed or complete description of a person.
This page explains exactly where 115 sits, what it reliably predicts, what it does not, and the single most important caveat that most "what does X IQ mean" pages skip: the answer depends on what kind of test produced the number.
Where 115 sits: the percentile and the rarity
Because IQ scores follow an approximately normal (bell-curve) distribution, position and rarity are fixed by the math. A score of 115 is at about the 84th percentile, meaning you scored higher than roughly 84 percent of the reference population. About 16 percent of people - around 1 in 6 - reach 115 or above.
For reference points on the same scale: 100 is the 50th percentile (the exact middle), 115 is about the 84th (1 in 6), 130 is about the 98th (1 in 50), and 145 is about the 99.9th (1 in 740). One standard deviation above the mean is a solidly above-average position, but it is far more common than the rarer scores further out - the bell curve is still fairly dense at this point and thins fast only toward the edges.
What a 115 actually predicts
General cognitive ability is the single best-evidenced psychological predictor of academic achievement and job performance, and the relationships are strongest in complex, knowledge-heavy domains. A score around 115 is associated, on average, with above-average capacity for abstract reasoning, comfortable acquisition of complex material, and good performance in demanding educational and professional settings.
The phrase "on average" is doing real work, though. These are population-level statistical relationships, not guarantees about an individual. Plenty of people at 115 thrive in highly demanding fields, and plenty of consequential achievement comes from people nearer the average who bring conscientiousness, opportunity, and persistence - traits a reasoning test does not measure.
What 115 does NOT mean
IQ measures reasoning ability, not worth, character, creativity, wisdom, or success. It is weakly related at best to many things people assume it governs: emotional skill, practical judgment, ethical behavior, and the ability to get along with others are largely separate dimensions, several of which we measure with different instruments.
An above-average score is also not a destiny or a personality. It describes how you performed on reasoning tasks relative to others, on the day you tested, on the test you took - nothing more. And 115 is not "almost gifted" in any meaningful sense: it is its own solid position on the curve, not a near-miss of a threshold that sits well above it.
- Not a measure of worth, character, or potential as a person
- Not the same as creativity, wisdom, or emotional intelligence
- Not "gifted" or a Mensa-qualifying score (that cutoff is 130, about the 98th percentile)
- Not a guarantee of achievement (motivation and opportunity matter enormously)
The caveat that changes everything: which test?
A 115 from an individually administered, professionally supervised test (such as the WAIS or Stanford-Binet) and a 115 from a quick online quiz are not the same evidence. Supervised tests have rigorous norms, controlled conditions, and validated items; many online tests have none of these and inflate scores to keep users happy.
This is why honest online tests, including ours, cap scores (we cap at 160) and report a band with a percentile rather than a false-precision point. If you saw 115 on an unsupervised test, read it as "likely above average" rather than as a certified figure - and treat any online result claiming to certify a precise standing with suspicion.

Frequently asked questions
Is a 115 IQ good?
Yes. A 115 is a solidly above-average score - about the 84th percentile, meaning you scored higher than roughly 84 percent of people. It sits at the start of the "above average" range (115 to 129), comfortably above the middle of the distribution, though below the conventional gifted threshold of 130.
What percentile is a 115 IQ?
About the 84th percentile - you scored higher than roughly 84 percent of the population. This follows directly from the scale: 115 is exactly one standard deviation above the mean of 100, and about 16 percent of people (around 1 in 6) score at or above it.
How rare is a 115 IQ?
Not especially rare: about 16 percent of people, or roughly 1 in 6, score 115 or above on a properly normed test. Scores get markedly rarer further out - 130 is about 1 in 50, and 145 is about 1 in 740.
Is a 115 IQ gifted?
No. The conventional cutoff for "gifted" or "very superior" is 130 (about the 98th percentile), which is also the entry point for high-IQ societies like Mensa. A 115 is above average and capable, but it is well below that threshold; on the standard bands it is the start of the "above average" range (115 to 129), not gifted.
