Given the importance of quality teaching for student success, it is clear that every child needs to be able to receive instruction from a teacher who possesses the knowledge and skills for quality teaching--an accomplished teacher. It is less clear, however, how current teacher development policies and practices can ensure that all students will have the accomplished teachers they need. In 2004, a broad-based coalition of Massachusetts's education stakeholders came together to construct a clear path to accomplished teaching by working toward common standards, a coherent system of supports, and shared accountability for quality teaching. Although the work of our coalition is unfinished, our experience thus far will be useful to the field as increasing numbers of districts and states are thinking strategically about how to develop the human resources needed to provide every child with accomplished teaching.
