Achieve and the U.S. Education Delivery Institute have developed a practical Common Core Implementation Workbook for all states in the Partnership for Assessment of Readiness for College and Careers (PARCC). This workbook uses a proven performance management methodology known as "delivery" to lay out clear action steps for states and districts. It provides relevant information, case stories of good practice, key questions and hands-on exercises for leadership teams to complete together. Regardless of one's timeline, the workbook offers state and district leaders the means to plan for the CCSS and then drive successful implementation. The workbook begins with a diagnostic assessment to help readers determine where their Common Core State Standards (CCSS) implementation effort is going well and areas of challenge that merit additional attention. After the diagnostic, the next sections of the workbook focus on how the state agency and school districts can organize for implementation. The workbook then offers a set of implementation actions that consist of the actual work of the CCSS transition. Chapters 5 and 6 help readers answer the critical questions for two key actions: how to align curricular and instructional materials and how to train educators on the CCSS. The workbook ends with Chapter 11, which answers the final question--how to monitor progress and sustain momentum, a topic that obviously applies across all the implementation actions. Individual chapters contain endnotes.
