Measuring Effects of the Common Core
This report’s analysis uses surveys of state implementation to model different Common Core State Standards (CCSS) starting points for states and produces a second early report card on how CCSS are doing. An initial report card that focused on math was presented in a previous Brown Center Report. The current study updates state implementation ratings that were presented in the first report and extends the analysis to achievement in reading. The goal of the paper is to estimate CCSS’s early impact, and also lay out a fair approach for establishing when CCSS’s impact began.
