This research explores the relationship between MAP and PSAE and MAP and ACT in an effort to suggest cut scores that can help educators determine a student’s academic trajectory. This study was conducted to answer the question: Are NWEA MAP, PSAE, and ACT scores related such that NWEA MAP scores can predict future student performance on the PSAE and ACT and if so, what are the minimum in a range of MAP scores needed for grades 5-10 that demonstrate that a student is on track to meet state standards on the grade 11 PSAE and the ACT college and career readiness benchmarks. Student NWEA MAP and PSAE or ACT test scores were paired according to the related subject area. Pearson correlation coefficients were found to be adequately high confirming linear relations among the test scores. Sequential logistic regression models were calculated and found to support the fact that adding additional years of student scores enhanced the predictive ability of the models. Thirty-six bivariate logistic regression models were then run to calculate the minimum in a range of cut scores for NWEA MAP that would indicate that a student was on track to meet standards on the grade 11 PSAE in math and reading, and the grade 11 ACT in math, reading, and English subject areas, and overall Composite score. Half of the models used MAP scores from grades 8-10 with grade 11 PSAE and ACT scores as the dependent variable in data set 1 and the other half of the models used MAP scores from grades 5-7 with a grade 8 MAP score as the dependent variable in data set. The grade 8 MAP score used in data set 2 was the result of the analyses from data set 1. Models were validated and final cut scores were presented and discussed.
