Since July 2005, all 50 state governors have signed the National Governors Association's Graduation Counts Compact on State High School Graduation Data. 30 states have now received Honor States grants, for which implementation of the Graduation Counts Compact is a core requirement. This is a significant step forward, but much work remains to be done. The National Governors Association Center for Best Practices is working with governors, their advisors, and other state officials to ensure timely and effective implementation of the compact. The NGA Center will also assist states in assessing their progress toward full implementation, and will work to assess implementation progress in a manner that is both the least burdensome and most accurate. (This document includes a framework for state implementation of the Graduation Counts Compact.)
