Question
How reliable is the MAP Growth test?

Answer
The banks of questions used on the MAP Growth tests are extensive and have been developed over many years. This has given our analysts ample opportunity to collect abundant evidence that establishes their reliability. NWEA test and re-test studies, which evaluate scores from the same students after a lapse of several months as opposed to several days, produce reliability indices that have consistently been above what is considered statistically significant.

For more information about the reliability and validity of the MAP Growth test, please contact NWEA Partner Support or your Account Manager for a copy of our MAP Technical Manual, which discusses the results of reliability and validity testing in detail.
