Read the scale before the label
Band names vary by test and publisher. They are conventions for interpreting a specified instrument, not natural categories of people. Check the test version, norm group, intended use and its uncertainty guidance before applying a label.
Illustrative normal-scale values
These are mathematical examples assuming a normal distribution with mean 100 and standard deviation 15. They are not observed frequencies from AurorIQ and do not establish diagnostic thresholds.
| Score | Approximate modeled percentile |
|---|---|
| 70 | 2.28 |
| 85 | 15.87 |
| 100 | 50.00 |
| 115 | 84.13 |
| 130 | 97.72 |
Percentile rank is relative position, not percentage correct. See the worked percentile calculation for the formula and why equal score gaps produce unequal rank changes.
What the table does not tell you
It cannot determine a person's diagnosis, support needs, giftedness, career suitability or potential. Evidence for a score's interpretation and intended use is central to the Testing Standards. A band label cannot replace that evidence.
AurorIQ is different
AurorIQ's current reasoning index is a proprietary 20–80 model scale and has no representative population norms. Do not convert that product index into this table's percentiles or professional classifications. Start with observed answers and the practical report, and read the methodology.
