Effective leaders support and promote teacher learning and student academic success. Even though policies address teacher instruction and preparation on reading, less attention is given to writing and even less to the role of principals and literacy leaders on the implementation of evidence-based practices on writing. Drawing from research on effective principals, and on guidelines offered by principals, who have engaged in genre-based strategy instruction on writing, the authors will provide suggestions for those who are interested in sustainable reform efforts on writing. The chapter will explain the genre-based strategy instruction approach, its professional development model, will comment on “lessons learned” across collaborations, and offer specific recommendations for district-wide and school-wide applications. Finally, implications for teacher-preparation programs will be discussed as those address literacy within leadership programs.
