States began adopting the Common Core State Standards (CCSS) in 2010 after they were launched by the Council of Chief State School Officers and the National Governors Association. Five years later, policymakers in numerous states continue to debate the Common Core and related elements, such as how to assess the standards. This brief provides a sampling of state legislative activity and executive branch action around the CCSS through Sept. 1, 2014. It is not intended to be an exhaustive list; rather, it is narrowly focused on the single issue of state affirmation, modification or replacement of the Common Core.
