Convert IQ ↔ GRE
How the conversion works
IQ and GRE scores are normalised on bell-curve distributions. The conversion maps a person's standing in one distribution to the equivalent standing in the other.
- IQ: mean 100, standard deviation 15.
- GRE (Verbal + Quantitative): mean ≈ 301, standard deviation ≈ 14, based on ETS GRE score reports. Note that this is normed to the graduate-bound population, which is already above the general-population mean.
IQ-equivalent = (target − meantarget) / SDtarget × 15 + 100
target-equivalent = (IQ − 100) / 15 × SDtarget + meantarget
Common IQ ↔ GRE reference table
| IQ | GRE | Percentile |
|---|---|---|
| 100 | 286 | ~50th (general population), ~10th (GRE takers) |
| 110 | 301 | ~75th (general population), ~50th (GRE takers) |
| 120 | 312 | ~91st (general population), ~78th (GRE takers) |
| 130 | 322 | ~98th (general population), ~94th (GRE takers) |
| 140 | 333 | ~99.6th (general population), ~99th (GRE takers) |
Important caveats
- IQ-GRE correlation is around 0.7. Because GRE takers are already a selected sample (people pursuing graduate study), GRE scores have a narrower distribution than IQ scores in the general population. The IQ-equivalent of an average GRE score is higher than 100.
- Extreme-tail conversions are less reliable because both tests have fewer calibration cases there.
- No score entered here is stored, submitted, or connected to an account.
