IQ 115
High Average
84.1% percentile • about 1 in 6
Quick Answer
An IQ of 115 is classified as High Average, placing you in the 84.1% percentile (about 1 in 6 at or beyond this score).
How this is calculated: percentile and rarity use a normal distribution with mean 100 and standard deviation 15. Real test norms, confidence intervals and ceilings differ, so treat the figures as approximations—not a diagnosis or a promise of educational or career outcomes.
Where IQ 115 Falls on the Distribution
The bell curve shows the normal distribution of IQ scores. The mean is 100 with a standard deviation of 15. The highlighted area represents the percentage of people who score at or below IQ 115.
What an IQ of 115 Means
High average intelligence indicates solid cognitive abilities above the population mean. Individuals at this level typically perform well in most academic and professional settings and can handle moderately complex work with good success.
Key Characteristics
- Solid reasoning and problem-solving abilities
- Good learning capacity and retention
- Capable of handling most professional demands
- Effective in structured learning environments
- Can manage moderate complexity well
One Standard Deviation Above Average
An IQ of 115 is exactly one standard deviation above the mean — a statistically significant boundary in psychometrics. This places you in the top 16% of the population, above 84% of people. Research by Herrnstein and Murray (1994) and Gottfredson (2003) identified IQ 115 as a key threshold where individuals begin to consistently outperform in complex information-processing tasks.
Real-World Analogy
Scoring IQ 115 is like running a 7-minute mile — solidly above average and noticeable, but not rare. In a typical classroom of 30 students, about 5 would score at or above this level. You pick up new concepts faster, read more efficiently, and solve novel problems more readily than most peers.
Education Context
IQ 115 is one standard deviation above the conventional mean. It can indicate relative ease with some academic reasoning tasks, but grades and degree completion depend on many other factors.
How It Compares
The jump from IQ 110 to IQ 115 crosses the one-standard-deviation threshold — moving from "high average" to the lower boundary of "superior." This 5-point difference shifts you from the 75th to the 84th percentile, which is measurable in academic and professional outcomes.
