Linking the Wisconsin Forward Assessments to NWEA MAP Growth Tests* (PDF):

The results in Table 5 demonstrate that MAP reading scores can consistently classify students’ proficiency (Level 3 or higher) status on Forward ELA test 81-83% of the time and MAP math scores can consistently classify students on Forward math test 86-88% of the time. Those numbers are high suggesting that both MAP reading and math tests are great predictors of students’ proficiency status on the Forward tests.”
