This study examines the implementation of academic supervision in rural Indonesian elementary schools, focusing on how instructional leadership practices are operationalized through planning, organization, execution, and collaborative engagement. Using a qualitative case study approach, data were collected through in-depth interviews, observations, and document analysis involving principals and teachers, and analyzed thematically using the Miles and Huberman framework. The findings reveal that academic supervision is implemented in a systematic, structured, and evidence-based manner that reflects contemporary instructional leadership principles. Planning is grounded in data-driven decision-making based on school evaluation results and teacher performance analysis, particularly in literacy and numeracy development. Organizational practices demonstrate adaptive grouping strategies that enable targeted and context-sensitive supervision. The implementation phase includes administrative verification, classroom observation, feedback delivery, and follow-up actions aligned with planned supervision objectives. In addition, supervision is conducted through a collaborative and distributed leadership model that strengthens coordination, shared responsibility, and teacher engagement. The process also adopts a reflective and developmental approach that encourages teacher openness, motivation, and professional growth. Overall, the study highlights that academic supervision functions not only as an evaluative mechanism but also as a continuous professional development system that enhances instructional quality and teacher effectiveness. These findings emphasize the importance of integrated instructional leadership in supporting sustainable school improvement at the primary education level.
