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 nationwide. 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 math 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 Math test numerous times in a short period of time, the score would likely fall in this range.
The Percentile Rank is included on the Annual Progress Report, the Diagnostic Report, the Growth Report, the Parent Report, the Screening Report, the Summary Report, and the Test Record Report.
The Percentile Rank is also used on some of the screening, benchmark, and progress monitoring pages.
