The mission of teacher leadership is to elevate teachers as experts and leaders in and beyond the classroom. This framework contains six spheres or dimensions, each describing a set of dispositions, core beliefs, knowledge base, requisite skills and unique roles for teacher leaders. While the spheres are interrelated, with each one broadening the stage for teacher leadership, it is not expected that individual teachers will fulfill every role. Rather, these six spheres suggest multiple roles for teacher leaders. Dispositions are enriched as teacher leaders work within the various spheres. In this report, the following six framework spheres are presented: (1) Leading from the Classroom: developing capacities of students and self; (2) Leading through Modeling and Coaching: developing capacities of peers; (3) Leading Groups and Teams: contributing to positive school change to enhance student learning; (4) Leading to Increase Teacher Voice and Influence: working to enlarge teachers' role in decision-making beyond the classroom and in concert with other stakeholders; (5) Leading to Professionalize Teaching: reforming educational systems to create greater opportunities for teachers to learn and lead beyond the local level; and (6) Leading to Connect to the Larger Community or World: expanding the world of the classroom beyond the school.
