What an IQ of 111 means
An IQ of 111 is higher than about 76.8% of people: roughly 1 in 4 score 111 or more. It is in the high average range, 0.73 standard deviations above the average of 100.
The amber band is the likely range on a retake of our test, 9 points either side. The curve is the normal distribution with a mean of 100 and a standard deviation of 15.
Is an IQ of 111 good?
Yes, it is above average: higher than about 76.8% of people, in the high average range.
What percentile is an IQ of 111?
An IQ of 111 is at the 76th percentile: it is higher than 76.8% of people on a scale with a mean of 100 and a standard deviation of 15.
Tests that use a different standard deviation give the same rarity a different number: about 112 on a 16-point scale such as older Stanford-Binet editions, and about 118 on the 24-point Cattell scale.
How rare is an IQ of 111?
About 1 in 4 people score 111 or higher. In a group of 1,000 people, about 232 would be expected to score that high or higher.
How much could a retake change it?
No test gives the same score twice. The likely range is where about 90 in 100 retakes would land, and its width depends on how reliable the test is.1
| Test | Margin of error | Likely range |
|---|---|---|
| Our test (reliability 0.87) | ±9 | 102 to 120 |
| A test with reliability 0.90 | ±8 | 103 to 119 |
| A test with reliability 0.95 | ±6 | 105 to 117 |
The margin is 1.645 standard errors of measurement, which covers about 90% of retakes.
What an IQ of 111 does not tell you
A score describes how someone did on one set of reasoning tasks on one day. It does not measure what a person knows, how hard they work or what they will achieve.
An online test is for interest. For a score that counts for school, work or health, a psychologist can give a full assessment in person.
