If successful school reform rests largely on the capabilities of individual teachers and groups of teachers to deliver high-quality instruction, then a key component of teacher workforce development is teacher learning. One of the prominent ways in which educational leaders shape school conditions and teaching practices is through their beliefs and actions regarding teacher learning. Of course, leaders must still attend to myriad important matters, such as selection, assignment, and retention of teachers; utilization of financial and other material resources; and cultivation of school-level leadership and school-family-community relations. But the shift to a greater emphasis on the instructional role of leaders should be paramount. In this paper, the author addresses school- and district-level leadership for teacher workforce development through improving teacher learning and capacity. He discusses how leadership can connect student learning, teacher professional learning, and system-wide learning with one another and with learning goals to promote coherence.
