Percentiles Quick Reference Guide

The Percentiles Quick Reference guide lists tables that contain the 10th, 25th, 40th, 50th, and 90th percentiles with each score correlating to a season. These tables only provide the details for these set intervals, if you need to find a more detailed score you can reference the Detailed Percentile Table.

Interpreting the Percentile Tables

Example: In this example, we look at a 5th grade student who took a Fall vocabulary benchmark test and scored a total of 15 correct. Next, to locate what percentile a score of 15 falls at, we take the total correct answers (15) and compare it to the 5th grade Fall Vocabulary chart in the guide. (pictured below)

Here our student's score of 15 falls on the cusp of the 40th percentile. Ideally, a student score should fall at the 50th percentile for them to be considered performing "on grade". If they are at the 50th percentile or above, no other testing in that area is needed until the next benchmark testing cycle. If they fall below the 50th percentile, an intervention with practice sessions will need to be applied in order to improve their score/percentile rank. Since this student's score falls below the 40th percentile, an intervention would be recommended containing practice sessions focused on 5th grade Vocabulary.
