Examining the Role of Major Interim Assessments in Predicting Student Performance Scores and Gains on a State Summative Assessment
In this research article from the "Educational Assessment" Journal, EA staff member Michael Christian and former Enhance Fellow at EA Shuyuan Li explore the marginal contribution of three widely used interim assessments – NWEA’s MAP, Curriculum Associates’ i-Ready, and Renaissance’s Star – in forecasting both performance scores and gains on a state summative assessment, conditional on prior state summative test scores. In this article, using data from South Carolina, they found that prior state assessment scores strongly predict EOY summative scores but have limited predictive power for year-to-year summative gains.
