Percentile Rank (PR) and Percentile Rank Range
Percentile Rank (PR) scores range from 1 to 99 and express student ability relative to the scores of other students in the same grade. For a particular student, this score indicates the percentage of students in the norms group who obtained lower scores.
For example, if a student has a Percentile Rank of 85, the student's reading skills are greater than 85% of other children in the same grade.
The Percentile Rank Range reflects the amount of statistical variability in a student's Percentile Rank score. If the student were to take the Star Reading test numerous times in a short period of time, the score would likely fall in this range.
The Percentile Rank is included on these reports: the Annual Progress Report, the Diagnostic Report, the Growth Report, the Parent Report, the Screening Report, the Summary Report, and the Test Record Report.
