What does an IQ of 80 mean?
An IQ of 80 falls in the Low Average band (80–89), a little below the population midpoint of 100. You scored higher than about 9% of people. On its own this measures a narrow kind of reasoning, and it's an estimate rather than a label.

Is an IQ of 80 good?
"Good" isn't the most useful frame here. An IQ of 80 is somewhat below the midpoint of the scale, but IQ captures only abstract reasoning — not memory for what matters to you, practical skill, creativity, or drive. Everyday reasoning and most jobs and courses remain well within reach, and a single online test is an estimate, not a fixed measure of a person.
How rare is an IQ of 80?
An IQ of 80 is fairly common: about 9% of people score lower and 91% score higher, so it sits within the normal spread of scores rather than at any extreme.
What an IQ of 80 looks like in practice
Differences within and just below the average band rarely show up clearly in daily life. Interest, effort, and familiarity with the kind of puzzles a test uses can move a single result more than people expect.
IQ 80 compared to nearby scores
No short test pins ability to a single point. An IQ of 80 is best read as the centre of a range — roughly 76 to 84 — rather than an exact value, and it is not meaningfully different from scores a few points either side. When you compare two people, overlapping ranges matter more than the point scores.

| IQ Range | Classification | % of People | What it means |
|---|---|---|---|
| ≤69 | Extremely Low | ~2.2% | Well below average. On clinical tests this range may warrant professional assessment. |
| 70–79 | Borderline | ~6.7% | Below average reasoning on this scale. |
| 80–89 | Low Average | ~16.1% | Slightly below the population average. |
| 90–109 | Average | ~50% | The middle of the distribution — where most people score. |
| 110–119 | High Average | ~16.1% | Above average reasoning ability. |
| 120–129 | Superior | ~6.7% | Notably above average — roughly the top 10%. |
| 130–144 | Gifted | ~2.1% | The conventional 'gifted' threshold (130) and above — top ~2%. Mensa qualifies here. |
