For students to become powerful learners, their teachers must engage in powerful learning themselves. Yet the professional learning many teachers experience is often disconnected from the curriculum, disconnected from specific students and their learning needs, and disconnected from their daily work. What is needed is a tightly connected "systems" focus on continually increasing the knowledge and skills of teachers in their context, with their colleagues, as central to improving student learning. At its heart this is an equity issue, ensuring that all students in a system have equal access to rich, high-quality learning. The framework provided in this report attempts to make visible the coordinated, multiple parts of a system needed to support deep, effective professional learning for adults so that they can improve student learning outcomes. The goal is to support system leaders who embrace professional learning as key to ensuring that each student engages in rich learning experiences every day and each teacher has an opportunity to reach their potential. The framework is based on extensive research and discussion among teachers, school and districts leaders, and partner organizations. The framework is expected to keep evolving based on learning from applying the framework and exploring its implications as well as from input from the field.
