Interpreting Norm-Referenced Scores Percentile Ranks Percentile ranks, which range from 1 to 99, are commonly used for reporting test results to students and their parents/guardians. You may interpret a percentile as the percentage of students in a norm group whose scores fall below a given student's scale score.
A percentile is the position of an observation in the data set relative to the other observations in the data set. Specifically the percentile represents the percentage of the sample that falls below this observation. 50th percentile because half of the data or 50% of the observations lie below the median.
