An IQ of 110 sits in the high average range on the Stanford-Binet and Wechsler scales. It is approximately the 75th percentile — meaning that 75% of the general population scores at or below this level, and 25% scores above.
The mean IQ is 100 by definition; the standard deviation is 15. So a score of 110 is 0.67 standard deviations from the mean.
What it tells you, and what it does not
An IQ score is a snapshot of cognitive ability at the time of testing. It correlates with academic performance, job complexity, and certain measures of life outcomes — but the correlation is far weaker than the popular imagination suggests. Roughly half of the variance in life outcomes is explained by factors entirely unrelated to IQ: persistence, conscientiousness, social ability, health, opportunity, and luck.
Alfred Binet treated the score as a question (“what does this person need in order to flourish?”) rather than a verdict. That framing has aged better than the alternative.
Career and educational fit
The Stanford-Binet was originally built to inform educational decisions, and that remains its strongest use. A score of 110 is consistent with middle management; skilled craft; small-business owners; many teaching and nursing roles.
None of these are deterministic. People with the score described above out-perform expectations regularly, and people with much higher scores under-perform regularly.
The same total score, very different profiles
An IQ of 110 is a summary number. The five-factor profile is what it actually means.
Two people who both score 110 on the Full-Scale IQ can have completely different cognitive profiles. One might be at 125 on Innate Intelligence and 95 on Working Memory. The other might be the opposite. The summary score is identical. The lived experience of having that mind is not.
This is the part of the modern Stanford-Binet that the old single-number IQ obscured, and the part that our online assessment reports back to you alongside the total.
Can the score change?
Yes, in some directions and within some bounds. Working memory and processing speed move with sleep, stress, and physical health. Knowledge moves steadily with reading and exposure. Visual-spatial reasoning improves with practice on tasks that demand it. Innate Intelligence is the most stable factor in adulthood, and even Innate Intelligence shows real movement over years of cognitively demanding work.
People who re-test on a different day, or after a period of meaningful change in their lives, often see their score shift by 5 to 15 points.
