Many education leaders may wonder how to implement sustainable policy changes that will benefit youth, families, and the community. Arielle Lentz, Laura Desimone, Amy Stornaiuolo, Katie Pak, Nelson Flores, Philip Nichols, Morgan Polikoff, and Andy Porter share findings from school change efforts in more than 170 districts in five states. They present six key strategies based on this work, and they share examples of how districts employed the success factors of specificity, consistency, power, and stability to help build authority, which in turn led to successful implementation of new policies, curriculums, and professional learnings.
