This paper describes Delaware's progress in implementing a comprehensive and coherent approach to education reform from the time of application through June 30, 2011. In particular, it highlights key accomplishments over the reporting period in the four reform areas: standards and assessments, data systems to support instruction, great teachers and leaders, and turning around lowest-achieving schools. With its Race to the Top win last year, Delaware embraced a unique opportunity, and responsibility, to dramatically improve student outcomes for all students in the state. Race to the Top is not just another grant program; rather, it has become the catalyst for comprehensive and sustainable statewide reform. Individual sections contain references and footnotes.
