The early stages of the Common Core State Standards (CCSS) initiative were largely occupied with debates over the merits of the standards and the feasibility of their adoption by the states. As the movement has matured, the focus of attention has shifted toward issues related to practical implementation, such as the readiness of teachers to actually enact the new standards in the classroom. To gauge state progress toward implementing the CCSS, Education First and the Editorial Projects in Education Research Center surveyed state education agency officials to gain their insights on the status of transition planning efforts. Recognizing that the movement toward a new set of standards could constitute a dramatic shift for many educators, administrators, and policymakers, our survey sought to examine how state leaders are preparing for this change, by collecting information on the steps involved in developing the capacity of their school systems to face challenges in several key areas.
