Linking New Mexico MSSA ELA Assessment to ISIP Reading

This technical report outlines the proficiency projection of Istation’s Indicators of Progress (ISIP) Reading in relation to the New Mexico Measures of Student Success and Achievement (NM-MSSA) English Language Arts (ELA) assessments for students in grades 3 through 6. The study analyzes data from six school districts in New Mexico, providing classification accuracy and correlation statistics between ISIP Reading scores and NM-MSSA ELA scores. The Pearson product-moment correlations indicate strong associations, with coefficients ranging from 0.70 to 0.77. The report details the percentile ranks required on ISIP Reading to achieve various performance levels on the NM-MSSA ELA, including Nearing Proficiency, Proficient, and Advanced. Additionally, classification accuracy analyses reveal that ISIP Reading correctly predicts student performance on the NM-MSSA ELA assessments approximately 80% of the time at both middle-of-the-year and end-of-the-year evaluations. The findings aim to assist educators in preparing students for state assessments.
