Question
What are the RIT scores used to sort goal area scores into ranges (for example: Low, Low Average, Average, High Average, High - also known as "goal descriptors")? What are the RIT cut offs or cut scores between each category or descriptor?

Answer
The 5 ranges (Lo, LoAvg, Avg, HiAvg, Hi - also known as "goal descriptors") in reports are based on the NWEA norms and correspond to percentile ranges of 20 points each, or quintiles. For example, the lowest quintile covers the 1st through 20th percentiles. Descriptors and corresponding percentile ranges are as follows:
  • Low: 20th percentile or lower
  • LoAvg: 21st to 40th percentiles
  • Avg: 41st to 60th percentiles
  • HiAvg: 61st to 80th percentiles
  • Hi: 81st percentile or higher

To determine which quintile a student's goal area score is in, we compare the student's goal score to the norms for the overall subject. We do not have separate norms or percentiles for each goal area. If the student's goal score is reported as a range (for example, 200-210), then the goal score we use to determine the quintile is the number in the middle of this range.

Goal descriptors can appear on the following reports:
