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 year. For a particular student, this score indicates the percentage of students in the norms group that 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 students in the same year.

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 the Annual Progress Report, the Diagnostic Report, the Growth Report, the Screening Report, the Student Progress Monitoring Report, the Summary Report and the Test Record Report.
