Reconciling long-term education policy goals with short-term school accountability models
Schools are increasingly held accountable for their contributions to studentsā academic growth in math and reading. Under The Every Student Succeeds Act, most states are estimating how much schools improve student achievement over time and using those growth metrics to identify the bottom 5% of schools for remediation.
Topics: Growth modeling, Measurement & scaling, Student growth & accountability policies
In this study, we apply the Compound Polynomial or āCPā model in a school evaluation context. The CP model addresses the seasonality of student test scores by simultaneously estimating between- and within-year growth.

School effectiveness, summer loss and federal accountability
Learn more about the effect of seasonality on estimates of school effectiveness and how ignoring summer loss can impact which schools are identified as low performers.
