As members of the National Association of Secondary School Principals (NASSP) Task Force on Principal Preparation, the authors recently completed a study of the changing role of the secondary principal. One striking finding was that multiple roles and responsibilities leave today's principal feeling chronically harried and overworked. For principals in small or rural schools, the problem is compounded by a lack of support personnel. To keep the focus on instruction while juggling multiple roles, many principals are developing teacher leaders among their staff members. In schools across the country, teachers are taking on the role of "instructional coach" by working part-time or full-time as facilitators of professional learning. By using the effective strategies presented in this article, principals can ensure that professional learning becomes a school norm.
