Is an IQ of 104 good?
An IQ of 104 is average, a little above the middle of the scale: higher than about 61% of people, and about 1 in 3 people score higher.
How rare is an IQ of 104?
In a room of 100 people, someone with an IQ of 104 would be smarter than 61 of them.
- Outscored: 61
- Would score higher: 39
Only about 39.5% of people score higher than 104. Here is what that looks like in groups of different sizes:
| In a group of | People scoring above 104 |
|---|---|
| A classroom of 30 | about 12 |
| A room of 100 | about 39 |
| A school of 1,000 | about 390 |
| A town of 10,000 | about 3,900 |
| A packed football stadium (70,000) | about 28,000 |
| A city of 1 million | about 395,000 |
| The United States (about 340 million) | about 134 million |
What an IQ of 104 means
An IQ of 104 is 4 points above the average of 100, or 0.27 standard deviations above the mean. It falls in the average band.
Scores from 90 to 109 are the middle of the scale, where half of all people land. An average score means your reasoning is typical for your age: not a ceiling, just the center of the curve.
What an IQ score predicts, and what it doesn’t
IQ is one of the strongest single predictors of school grades: a meta-analysis of 240 samples put the correlation at about .54 (Roth et al., 2015). For job performance the estimate depends on the statistical corrections used: .51 in the classic review (Schmidt & Hunter, 1998) and .31 in a 2022 re-analysis (Sackett et al.). Either way, most of the differences between people come from other things: knowledge, effort, personality and opportunity.
How a 104 does on our test
On our free 30-question test, an IQ of 104 takes about 17 correct answers out of 30. Here is how 17 correct answers usually split across the four areas:
- Pattern reasoning 6 of 10
- Numerical reasoning 5 of 7
- Verbal reasoning 3 of 6
- Logical reasoning 3 of 7
Worked out from our scoring model, assuming the easier questions are the ones you get right. Harder questions count for more, so two people with the same number correct can score a few points apart. We’ll replace this with real results once enough people have taken the test. How scoring works
Jobs where the typical worker scored about 104
In a study that followed Wisconsin men from high school into their 50s, these job groups had a typical (median) score closest to 104. 33 of the 56 groups had a median below 104.

Source: Hauser (2002), Wisconsin Longitudinal Study, Figure 12. The study covers men who finished high school in Wisconsin in 1957 and their brothers, with IQ measured in high school (Henmon-Nelson test, group average 102) and jobs held in 1992–94. Groups with fewer than 30 people are left out, and people who left school early aren’t in the study, so low scores are under-represented. Every job spans a wide range: 27 to 42 points between its 10th and 90th percentile.
IQ 104 on other scales
Not every test uses the same scale. The same performance that earns 104 on a modern test with a standard deviation of 15 produces a different number on tests with a wider spread:
| Scale | Spread | Equivalent |
|---|---|---|
| Standard IQ (Wechsler, Stanford-Binet 5) | SD 15 | 104 |
| Older Stanford-Binet and some online tests | SD 16 | 104 |
| Cattell Culture Fair | SD 24 | 106 |
| z-score | mean 0, SD 1 | +0.27 |
| T-score | mean 50, SD 10 | 53 |
| Stanine | 1 to 9 | 6 |
| Percentile | 0 to 100 | 61st |
