Improving the quality of education is a shared responsibility, and supervision serves as a crucial strategy for enhancing teacher professionalism in planning, implementing, and evaluating instruction. Although the supervisor plays a multifaceted role, implementation in the field faces challenges such as limitations in the principal's supervisory competence, time constraints, and a work culture that does not fully support collaboration. This study aims to describe the planning, implementation, evaluation, and follow-up of principal supervision regarding teacher performance improvement at SD Inpres Passue. The research focuses on the principal's role in enhancing teacher performance. A qualitative approach using a case study design was employed. Data were collected through observation, interviews, and document analysis. Informants included the school supervisor, the principal, the deputy principal for curriculum affairs, and a fifth-grade teacher. Data analysis was conducted interactively, involving data collection, data condensation, data display, and conclusion drawing/verification. Research findings: 1) Academic supervision planning at SD Inpres Passue involves scheduling supervision at the beginning of the academic year, aligned with the educational calendar, with assessment instruments prepared systematically. 2) Academic supervision is implemented directly in the classroom through intensive observation over a two-week period, with teachers completing reflection forms before and after the observation; despite some obstacles during observation, teachers demonstrated readiness and adaptability; 3) Evaluation results indicate a significant improvement in teacher performance, particularly regarding administrative tasks and instructional materials. Follow-up actions included educational training and directives to participate in further training for continuous improvement. Overall, the implementation of principal supervision at SD Inpres Passue proved highly effective in improving teacher performance through meticulous planning, structured implementation, and consistent evaluation and follow-up.
