This report looks specifically at the information and data needs of policymakers related to the Common Core State Standards (CCSS) and the types of research that could provide this information. The ideas in this report were informed by a series of meetings and discussions about a possible research agenda for the Common Core, sponsored by the Center on Education Policy (CEP) at The George Washington University, and attended by representatives of education policy organizations, researchers, and other key stakeholder groups. The conversations at the meetings yielded four areas of policy-related research that were determined to be needed in the next year: (1) case studies of successful implementation of the CCSS; (2) studies of state and local CCSS outreach strategies; (3) studies of state education agency capacity to lead the CCSS implementation; and (4) analyses of the impact of federal education requirements on CCSS implementation. This paper examines each area in detail. [This report was written with the assistance of Nancy Kober.]
