The low quality of education in Indonesia is caused by the low competence of educators. To improve the teaching and learning process, teachers must be responsible and accountable. The school principal’s strategic management values can also contribute to educational improvement. The principal’s role includes planning, organizing, mobilizing, and evaluating resources to achieve the school’s vision, mission, and goals.
