This study examines the effect of educational leadership practices on the education quality of secondary schools in South Sudan. A mixed-methods approach, combining qualitative and quantitative research methods, was employed to gather data from 350 students through questionnaires and interviews. The results of the regression analysis revealed a significant positive relationship between educational leadership practices and education quality. Specifically, strong communication skills, an effective decision-making style, instructional leadership, and a positive school climate and culture on the part of the educational leadership were associated with higher levels of education quality. The study underscores the importance of educational leaders prioritizing the development and enhancement of their leadership practices to support education quality for student success. Recommendations include providing targeted training and professional development opportunities for leaders to improve their leadership skills and creating a supportive and collaborative school environment that values effective educational leadership practices. By investing in educational leadership development and ensuring they have the necessary skills and resources, all stakeholders can help improve education quality for the best academic outcomes for students in South Sudan. The findings of this study contribute valuable insights for educational institutions and policymakers aiming to enhance education quality through effective educational leadership practices.
