Standards-based education (S.B.E.) has been the dominant educational reform movement since the early 1980s, reinforced by federal and state accountability systems. This book examines the efforts of educational leaders in implementing S.B.E. to improve student achievement in a variety of demographic contexts but with common challenges. Four stages of S.B.E. implementation are identified that focus on strong district leadership of the articulation of how S.B.E. can benefit students, an investment in collaborative structures and teacher training, and the facilitation of dialogue among all educational stakeholders. The descriptions of leadership actions and educator development at each stage can serve as a guide for educators and policy makers to assess which stage schools and districts are in and what steps can be taken to effectively move S.B.E. reform efforts forward. The reflective questions for district, school, and teacher leaders at each stage can facilitate the dialogues that can ensure that S.B.E. reform supports changes in classroom instruction that improve the learning opportunities and educational outcomes of all students.
