In August 2015, the National Center for Education Research (NCER) convened a technical working group (TWG) for advice on how to strengthen NCER's portfolio of research on the influence of school leaders on student outcomes. The TWG included nine education researchers and practitioners with experience designing and conducting research on school leadership and Department of Education staff. The TWG discussion focused on four areas: (1) theories about the relationship between school leadership and student achievement, (2) leadership standards, (3) professional development, (4) impact of school leaders on student achievement. This meeting summary covers the major points of discussion and the recommendations that were offered.
