Researchers have found that despite the top-down pressures to assume an instructional leadership role, school principals demonstrate limited direct involvement in such leadership. The current qualitative study aimed to expand inquiry into inhibitors of instructional leadership in Israeli principals. Data analysis uncovered that Israeli principals' perceptions served as key inhibitors of instructional leadership, identifying three main perceptual inhibitors: (1) perceptions regarding principal-teacher relationships; (2) perceptions regarding the role of the principal; and (3) perceptions regarding the goal of schooling. These findings expands the available knowledge by illustrating how for Israeli principals, the inhibitors of instructional leadership did not only involve the constraints and capabilities of school principals but also deep disagreements with the conceptual framework that underpins instructional leadership.
