How this calculation works
The lookup uses the fixed percentile-to-stanine bands in the STS interpretive manual. Keep the same national or local comparison group as the percentile on your report.
Using the result
- Enter a reported percentile, not a percent-correct score.
- This does not convert raw or standard scores, calculate a composite, or predict admission.
