Growth and Norms

As you use MAP Growth data, refer to these common questions.

Also use the following 2015 Norms Resources to help your educational decisions.

Overview of MAP Growth Data

By using MAP tests, your schools can gain insight into the growth of all students, both low and high achievers. What makes it possible is the NWEA MAP norms study, which is representative of schools across the nation. NWEA norms enable you to compare student achievement in a single term (a "status norm"), as well as across terms (a "growth norm"):

Use growth norms to:

  1. project the amount of growth that is typical for similar students
  2. set appropriate growth targets, based on the projection
  3. evaluate the observed growth in a subsequent term

CAUTION: You may notice discrepancies between your MAP reports and the figures published in these norms resources, depending on your Weeks of Instruction between testing. Your Weeks of Instruction (a setting in your MAP preferences) may differ from the default. As a result, percentile rankings and growth projections will adjust on your MAP reports to more precisely reflect your students' amount of instruction. In contrast, these norms resources assume the default weeks of instruction (Fall = 4 weeks, Winter = 20 weeks, Spring = 32 weeks).
