This practice report from the George W. Bush Institute highlights central office practices that support school leaders. It emphasizes that principals play a critical role in school improvement and student success, and, therefore, central offices should adopt a “customer service” approach, prioritizing the needs of principals alongside those of schools. The report outlines seven key practices for central offices: (1) treating schools as clients, (2) selecting staff with the right mindset and skills to support schools, (3) reinforcing customer service skills, (4) structuring central offices to meet school and student needs, (5) communicating effectively with principals, (6) designing responsive administrative systems, and (7) gathering principals’ input to inform decisions. This resource provides concrete steps for addressing challenges and improving practices within school districts. Principal preparation faculty can use this report to guide future leaders in understanding how central offices can better support principals.
