What does my IQ score mean?
An IQ score tells you where your reasoning performance sits relative to a reference population, on a scale centred at 100 with a standard deviation of 15. Roughly 68% of people score between 85 and 115, and about 95% score between 70 and 130.
The percentile is the more intuitive number: a score of 120 corresponds to about the 91st percentile, meaning around 91 of every 100 people in the reference sample scored lower.

Approximate values on the standard 100-mean, 15-SD scale.
| IQ score | Approx. percentile | Common label |
|---|---|---|
| 130+ | 98th and above | Very superior |
| 120–129 | 91st–97th | Superior |
| 110–119 | 75th–90th | High average |
| 90–109 | 25th–74th | Average |
| 80–89 | 9th–24th | Low average |
| 70–79 | 2nd–8th | Borderline |
| Below 70 | Below 2nd | Requires clinical assessment |
Why your score is a range, not a point
Every measurement carries error. Testora IQ reports a 90% confidence interval of about ±4 points, so a reported 112 is best understood as "very likely 108 to 116". Small differences between two sittings are usually measurement noise rather than real change.
How to read your Testora IQ domain profile
The overall score hides useful detail. Two people with identical IQ scores can have very different profiles — one strong in pattern recognition and weak in working memory, the other the reverse — and those profiles imply different study strategies.
Your Testora IQ report shows each of the five domains separately, along with a personalised explanation of which strengths to lean on and which to train.
- Compare domains against each other, not against other people's scores.
- Treat gaps larger than one domain band as the actionable signal.
- Re-test no sooner than 90 days apart to reduce practice effects.
