Research has shown the importance of effective principals for student achievement, graduation rates, and attendance, teacher satisfaction and retention rates, school climate, and more. Importantly, research has also shown that the preservice and in-service learning opportunities principals have make a difference in their abilities to realize these positive outcomes for students and teachers. Marjorie Wechsler, Principal Research Manager at the Learning Policy Institute, will present findings from the report Developing Effective Principals: What Kind of Learning Matters. In the presentation she will discuss the elements of high-quality principal learning that research has associated with positive school, teacher, and student outcomes; examine the extent to which principals have opportunities to participate in learning experiences with those elements; and discuss state and local policies and practices that drive both the development of high-quality learning opportunities and access to them.
