<![CDATA[Educational quality is a key issue that determines a school’s ability to develop students’ competencies. One strategy introduced in Indonesia to improve quality is School-Based Management (SBM), which emphasizes decentralization of authority, community participation, accountability, and visionary leadership. This study aims to analyze the implementation of SBM at UPT SDN 03 Koto Baru and its relationship with educational quality, including academic achievement, student attendance, and stakeholder satisfaction. A mixed-methods approach with an explanatory sequential design was employed: quantitative analysis through questionnaires (teachers N=18, parents N=100), student report cards (N=136), and attendance data, followed by interviews, observations, and document reviews. Results show that the average SBM implementation score was 3.43 (moderate category), with school leadership (3.72) and learning management (3.68) as the strongest aspects, while community participation (3.10) and financial management (3.20) remained weaker. Educational quality indicators revealed an average academic score of 72.4, student attendance of 88.6%, parental satisfaction of 3.40, and teacher satisfaction of 3.65. Correlation analysis indicated a significant positive relationship between SBM implementation and educational quality (r=0.48 for academic scores; r=0.35 for attendance). Multiple regression yielded R²=0.42, with leadership (β=0.29; p=0.01) and learning management (β=0.36; p=0.002) significantly influencing learning outcomes. In conclusion, SBM implementation at SDN 03 Koto Baru is at a moderate level, with strengths in leadership and instructional management, while limited community participation and inadequate facilities remain key challenges.]]>
