Recognizing the importance of instructional leadership in improving classroom instruction, the University of Washington Center for Educational Leadership (CEL) works in partnership with districts to help school leaders increase their knowledge of what is being taught and their capacity to identify if it is being taught well. The scope of a CEL-district partnership is broader than just instructional leadership, touching all parts of the system; but, as its name implies, the work is focused predominately on school leaders. In this session, participants will learn about how this partnership attempts to increase the existing level of skill by providing professional development for school district administrators, principals, and district coaches.
