Book excerpt: Leading School Culture through Teacher Voice and Agency helps school leaders uncover, understand, and build the skill set to engage teachers in the work of school culture as they navigate the changes needed to improve the achievement for all students. This book presents a Framework for School Culture that explores how school culture, when acted upon through teacher voice and agency, is an untapped resource that can move schools forward. By supporting teacher voice and agency, the school and its teachers and leaders move toward taking collective responsibility for sustaining a culture of improvement that is stronger and more responsive. This research-grounded book is rich in practical tools to help leaders work with teachers, ensuring all the educators in a school are taking ownership over their own learning and developing the skills to reshape school culture to ensure students, teachers, and community members thrive.
