A common method used to interpret raw scores is to convert them into percentile rank. The broad application of percentile rank in almost all norm‐referenced tests, and the exclusive use in some tests, requires the conversion of raw scores. Because percentile rank is not a linear transformation of raw scores, percentile‐rank transformation in the lower and upper part of the raw‐score distribution relates percentile rank and raw scores differently than in the center of the raw‐score distribution. This paper describes the popularity of using percentile rank and offers an interpretation of the use of percentile rank with normal and skewed score distributions.
