<![CDATA[School facilities and infrastructure management is one of the essential components in improving the quality of education. Effective managerial supervision by the principal plays a strategic role in ensuring that educational facilities are planned, utilized, maintained, and evaluated systematically. This study aimed to analyze the implementation of the principal's managerial supervision in managing educational facilities and infrastructure at Sekolah Menengah Pertama Swasta Yayasan Pendidikan Wanita Islam Muslimat Jambi. The study employed a qualitative approach using a case study design. Data were collected through observations, semi-structured interviews, and documentation involving the principal, vice principal, teachers, administrative staff, and the school foundation. The collected data were analyzed using the interactive model of Miles, Huberman, and Saldaña, including data condensation, data display, and conclusion drawing. The findings (simulation) indicate that managerial supervision was implemented through four interconnected stages: planning, implementation, evaluation, and follow-up. The principal involved school stakeholders in identifying facility needs, conducted periodic monitoring of educational resources, evaluated the condition and utilization of school facilities, and implemented follow-up actions through maintenance, repair, and procurement planning. Several supporting factors included leadership commitment, collaboration among school members, and foundation support, while budget limitations and facility maintenance costs remained significant challenges. The study concludes that effective managerial supervision contributes positively to improving the management of educational facilities and infrastructure, supports a conducive learning environment, and enhances the overall quality of educational services.]]>
