School Leadership and its Impact on Reforms: A Narrative Review

Abstract

With educational reforms increasingly dependent on the capacity of schools to translate policy into changes in teaching, learning and equity, many reforms fail because their enactment is constrained at the school level by limited leadership capacity, autonomy and resources. This article presents a narrative review of how different leadership styles affect the implementation and sustainability of educational reforms in K-12 public and private schools. It synthesises literature published mainly between 2020 and 2025, comparing transformational, transactional, instructional and distributed leadership, and examines the mechanisms and barriers that shape reform outcomes. The review finds that no single leadership style is universally effective; sustained reform instead depends on integrating complementary leadership functions. Instructional leadership connects the reform agenda to the classroom through teacher development and curriculum alignment; transformational leadership builds shared vision and commitment; distributed leadership strengthens collective ownership; and transactional leadership provides accountability and consistency. Three mechanisms are identified through which leadership influences reform: strengthening instructional practice, building reform-oriented cultures, and mobilising resources strategically. However, leadership effectiveness is frequently constrained by limited autonomy, unequal resource allocation, the digital divide, and institutional constraints, so that the same practices produce different outcomes across schools. The article proposes a Reform-Ready Leadership Framework organised around three interconnected dimensions: vision and culture, instruction and innovation, and adaptive resource management. Future research is needed to empirically test and validate the framework across diverse school contexts.
