The aim of this study is to validate a stakeholder participation model in school management and assess its impact on improving management quality and educational outcomes. The research examines factors that facilitate stakeholder involvement in school management processes and analyzes its role in enhancing academic and administrative performance in schools. This study adopts a qualitative approach using a case study design to analyze schools with varying levels of stakeholder involvement. Data were collected through semi-structured interviews with school administrators, teachers, parents, and students in public schools. Additionally, school performance and management processes were reviewed. To assess the relationships between stakeholder participation, school management processes, and educational outcomes, Structural Equation Modeling (SEM) was employed. The validity and reliability of the data were ensured through triangulation and expert feedback. The findings indicate that active and continuous involvement of stakeholders, including parents, teachers, and the local community, significantly improves school management practices, financial transparency, and educational outcomes. Key success factors in stakeholder involvement include clear communication, regular participation in decision-making processes, and alignment of educational goals among stakeholders. Structural Equation Modeling (SEM) confirmed the positive relationship between stakeholder involvement and improvements in academic performance, resource allocation, and school governance. This study concludes that stakeholder involvement plays a crucial role in improving school management quality and educational outcomes. Schools with active stakeholder engagement in management processes typically achieve better academic performance, resource allocation, and school governance. Policymakers and educational leaders are encouraged to implement inclusive management practices to fully harness the benefits of stakeholder participation.
