Data Drift and Other Anomalies: MAP Growth Reportage in Three Urban Districts

• In Event: Student Growth

Abstract

This ongoing study compares ten years of same-student data from NWEA and state testing in three urban districts. Preliminary z-score analysis reveals large and persistent anomalies between many comparable NWEA and state test distributions. This finding casts doubt on the claim that NWEA reportage consistently reflects statewide learning standards.
