Linking California Smarter Balanced to ISIP Reading

This research report presents a study that examines the proficiency projection of Istation’s Indicators of Progress (ISIP) Reading in relation to the Smarter Balanced reading assessments for students in grades three through six. The study analyzes data from 1,258 students across various grades in a California school district. It highlights the strong correlations between ISIP scores and Smarter Balanced assessments, utilizing multinomial logistic regression to determine the likelihood of students achieving proficiency levels. The report details the classification accuracy of ISIP Reading in predicting performance on Smarter Balanced assessments, indicating that approximately 80% of students were correctly classified at the middle of the year (MOY) and 82% at the end of the year (EOY). The methodology section outlines the use of computer-adaptive tests for ISIP Reading and the structure of the Smarter Balanced assessment system, providing insights into the assessment processes and their implications for educational practice.
