What Does an IQ of 124 Mean?
Key facts about IQ 124
- 124 is in the range that studies commonly report as the average for physicians, attorneys, and PhD holders — demanding professions cluster here rather than above 130.
- In a random group of 100 people, someone scoring 124 would typically out-score about 95 of them.
- Roughly 444 million people worldwide would score 124 or higher — and about 7.7 billion would score below it.
IQ 124 in depth
An IQ score of 124 falls in the superior band (120–129), around the top decile of the population. Statistically, in a random group of ten people, someone scoring here is likely the strongest abstract reasoner in the room.
This range reliably shows up in real life: faster grasp of novel systems, comfort with multi-step abstraction, and an easier time with the kind of dense material that anchors technical and professional education. Studies of demanding professions — physicians, attorneys, engineers, professors — find their average scores typically landing in this band, not in the stratosphere above it.
Two honest caveats. First, at this level further points buy less than people assume: execution, communication, and persistence dominate outcomes. Second, a superior score raises expectations others place on general performance, while actual ability remains domain-shaped — a 125 composite can coexist with an unremarkable memory or average verbal fluency.
What this range tends to look like day to day
- Dense technical or theoretical material is digestible without translation
- Often the person who spots the structural flaw in a plan first
- Boredom in under-stimulating environments is a real productivity risk
- Peers may assume everything is effortless — invisible work stays invisible
For a score of 124, the most evidence-backed takeaway concerns fit rather than status: people in the superior band consistently report higher satisfaction and output in roles with genuine problem-solving latitude. The score is a signal about the kind of work that will feel sustaining, more than a rank to display.
IQ 124 on other test scales
Different tests use different standard deviations, so the “same” performance produces different numbers. A 124 on an SD-15 test (Wechsler-style, and this site) corresponds to:
| Scale | Used by | Equivalent score |
|---|---|---|
| SD 15 | Wechsler (WAIS/WISC), most modern tests, this site | 124 |
| SD 16 | Older Stanford–Binet forms | 126 |
| SD 24 | Cattell (used by some high-IQ societies) | 138 |
| Percentile | All scales | 95th |
Where 124 sits among all classifications
| Range | Classification | Share of population |
|---|---|---|
| ≤ 69 | Extremely Low | 2.1% |
| 70–79 | Borderline | 6.5% |
| 80–89 | Low Average | 15.6% |
| 90–109 | Average | 49.5% |
| 110–119 | High Average | 16.6% |
| 120–129 | Superior ← IQ 124 | 7.2% |
| 130–144 | Very Superior (Gifted) | 2.3% |
| 145–159 | Highly Gifted | 0.1% |
| 160+ | Exceptionally Gifted | <0.1% |
How reliable is a score of 124?
Any single IQ score has a measurement error of roughly ±5 points, and scores from unsupervised online tests vary more than professionally administered ones. Treat this number as the middle of a range, not a fixed property of your brain.

Is an IQ of 124 good?
Yes. An IQ of 124 is well above average — it places you at the 95th percentile, above roughly 95% of people. The conventional gifted threshold is 130, 6 points above this score.
What percentile is an IQ of 124?
On a standard scale with mean 100 and SD 15, an IQ of 124 is at the 95th percentile (z-score 1.60). That means about 95% of people score below it.
How rare is an IQ of 124?
About 1 person in 18 scores 124 or higher. Worldwide, that is on the order of 444 million people.
Is an IQ of 124 gifted?
Not by the most common definition: the usual gifted cutoff is 130, and 124 is 6 points below it. Given the ±5-point measurement error of any single test, a score of 124 means a retest could plausibly land closer to the line.
Can I raise an IQ of 124?
Measured scores move with test familiarity, sleep, stress and effort — often by 5–10 points — so a first online attempt frequently understates ability. Underlying fluid intelligence, however, is stable in adulthood: "brain training" apps have repeatedly failed to raise it. What reliably grows is domain skill and knowledge, which is what actually drives most real-world performance.
