This document summarizes research on principal leadership behaviors and how they influence teacher job satisfaction. It explores 13 core competencies of effective school leaders identified in prior research, including visionary leadership, unity of purpose, and instructional leadership. The literature review finds teacher job satisfaction is enhanced when principals exhibit behaviors from these competencies, such as supporting teacher development, fostering collaboration, and involving teachers in decision-making. Specifically, principal behaviors that create supportive working conditions, opportunities for input, and collegial relationships can increase teacher motivation and job satisfaction.
