On the standard scale (mean 100, SD 15), a score of 102 sits essentially at the population mean — the 55th percentile, meaning it matches or beats about 55% of the adult population. Test manuals file it under "average" (about half of everyone).

Statistically, scores in this range predict typical performance on abstract, novel material — and next to nothing about any individual life. The middle of the distribution is where the scale has least to say: interests, work habits and circumstances swamp a few IQ points in every direction.

Is an IQ of 102 good?

It is a solidly typical score — the range 90–109 holds about half of everyone, and everyday life, most jobs and most goals are built for exactly this range. Within it, small differences carry no practical meaning.

How rare is an IQ of 102?

About 1 person in 2 scores 102 or higher — it marks the 55th percentile, essentially at the population mean.

Could my "real" IQ differ from a test score of 102?

Almost certainly, by a little. Even excellent tests carry ±3–5 points of measurement error, online tests more, and the same person swings several points between good and bad days. Read 102 as "probably between 95 and 109" from a good test — wider from a casual one. Any result quoted without an error range is overclaiming.
