How does adjusting instructional weeks impact reports?

If you change the weeks of instruction in your MAP Growth settings, you will likely see a corresponding change in percentiles and growth projections on reports for that term. RIT scores, however, will not change. Read on for more details.

NWEA offers two types of student norms, status norms and growth norms, and both types consider the number of weeks of instruction that a student has received prior to taking the MAP Growth assessment.

How weeks of instruction affect status norms

Status norms provide a context for knowing how a student’s score at a single point in time compares to other U.S. students in that grade who have received the same amount of instruction. For example, a 5th grader with a math RIT score of 211 after having received 4 weeks of instruction is approximately at about the 49th percentile, relative to other U.S. 5th graders. However, if a 5th grader produced that math score after 16 weeks of instruction, they would be at the 38th percentile, relative to other 5th graders, because U.S. 5th graders with the additional 12 weeks of instruction tend to show higher scores.

How weeks of instruction affect growth norms

Growth norms change with instructional weeks in that, all other things being equal, more growth tends to occur over a span of more weeks. For example, a 5th grader student with 16 weeks of instruction between math MAP Growth test administrations would be expected to show more growth than a similar student with only 8 weeks of instruction between test administrations.
