Instructional leadership is the set of practices that principals use in relation to the improvement of teaching and learning. It is a strong predictor of how teachers collaborate and engage in a reflective dialogue about their practice. In most countries and economies, the majority of principals act as instructional leaders, though one-third rarely engage in any of this type of action. Distributed leadership is the ability of schools to incorporate different stakeholders in their decisionmaking processes. This type of leadership appears to advance the creation of a shared sense of purpose within schools. Nearly all schools involve their staff in decision-making processes, but they differ concerning the opportunities that are offered to students and their parents/guardians to be involved in school decisions. Principals who acquired instructional leadership competencies through training, or in a separate course, are more engaged in instructional leadership actions in their school than principals who have not participated in such training.
