Interpreting easyCBM Results

When interpreting easyCBM results, it is important to refer to the "percentile rank" associated with a given score at the time of year the measure was administered. These percentile ranks are based on national norms, which are re-calculated and updated every five years. Because of the way percentile ranks work, performance at or near the 50th percentile rank can be interpreted as average performance for students in that grade level.

For more info on viewing percentile rank scores, please see: Percentile Quick Reference Guide and Detailed Percentile Table

Scores above the 50th percentile rank indicate performance above average for students in that grade at that time of the year, and scores below the 50th percentile rank indicate performance below average for students in that grade at that time of the year. The easyCBM system has a variety of reports designed to help teachers identify students at risk, pinpoint what content they may need additional support with, and track improvements over time.

In general, the goal is to have students performing at the 50th percentile (gray line on graph) in their given grade at a given time of the year. Students who score at or above the 50th percentile will not need further testing until the next benchmarking period. Those that score below the 50th percentile are indicating an intervention with practice sessions will need to be applied in order to improve their score/percentile rank by the end of the season.
