The Impact of School Leadership on Academic Performance in Public Secondary Schools: Empirical Evidence from Kasese District, Uganda

Abstract School leadership is a critical determinant of students’ academic performance because it shapes teacher commitment, instructional focus, and the overall learning climate. Although prior research consistently documents a positive association, less is known about how specific contextual conditions amplify or constrain this relationship. This study examines the influence of school leadership on academic performance in public secondary schools in Kasese District, Uganda, while attending to contextual realities that may moderate effects. Using a cross-sectional mixed-methods design, we gathered data from head teachers, teachers, and students across eight schools. Quantitative analyses revealed a moderate positive correlation between leadership practices and student performance (r = .458), indicating that stronger leadership is associated with better academic outcomes. Practices most salient to improved results included effective communication that clarifies expectations, teacher motivation through recognition and constructive feedback, and accountability systems that align responsibilities with measurable goals. Qualitative findings reinforced these patterns, showing how visible, supportive leadership elevates teacher morale, promotes classroom consistency, and sustains purposeful learning. At the same time, persistent constraints—limited resources, bureaucratic bottlenecks, and uneven community support—dilute leadership gains and impede sustained improvement. These barriers divert leaders’ attention from instructional priorities and restrict opportunities for teacher development. The findings underscore two imperatives: targeted leadership development that prioritizes communication, data-informed decision-making, and staff motivation; and systemic efforts to mitigate environmental constraints by streamlining administrative processes, ensuring essential materials, and strengthening school–community partnerships. Future work should probe complementary drivers of performance, including parental engagement, pedagogical practices, and learning materials, ideally through longitudinal or quasi-experimental designs that illuminate causal pathways. While the cross-sectional design and reliance on self-report data limit causal inference and generalizability, the evidence supports a clear conclusion: strengthening leadership practices and addressing contextual challenges can create the supportive conditions that enable teachers and students to realize their full potential.
