Predicting Proficiency on Ohio's State Tests from MAP Growth Scores

This technical report outlines a linking study that predicts student proficiency on Ohio's State Tests (OST) in grades 3–8 based on MAP Growth scores. The study utilizes statistical analyses to establish Rasch Unit (RIT) cut scores that correspond to performance levels on the OST for mathematics and English language arts (ELA)/reading, as well as science. The linking study is based on data from 71,975 students across 48 districts who took both assessments in Spring 2022. The report details the methods used for data collection, post-stratification weighting, and classification accuracy, as well as the results of the proficiency projections. It confirms the alignment of MAP Growth and OST assessments and provides cut scores for various grade levels. The report also includes classification accuracy statistics to demonstrate the effectiveness of MAP Growth scores in predicting student performance on state assessments. Educators can utilize these findings to monitor student progress and ensure they are on track for proficiency.
