Exploring Instructional Supervision Practices among Master Teachers and Supervisors in SDO Santiago City

Instructional supervision plays a critical role in strengthening teaching quality, supporting teachers' professional development, and ensuring the effective implementation of curriculum standards. This qualitative study explored the instructional supervision practices of master teachers and supervisors in the Schools Division Office (SDO) of Santiago City, Philippines. Specifically, it examined how instructional supervision was conducted, how supervisors and master teachers provided technical assistance and professional support, the challenges encountered in supervisory work, the strategies employed to respond to these challenges, and the practices that could contribute to a more responsive instructional supervision framework. The study employed a qualitative descriptive research design and purposive sampling of master teachers and education supervisors with direct experience in instructional supervision. Data were gathered through semi-structured interviews and were analyzed using thematic analysis through familiarization, coding, categorization, theme development, review, and interpretation. Five interconnected themes emerged from the analytic framework: (1) supervision as developmental professional support, (2) observation and feedback as mechanisms for improving instruction, (3) collaborative coaching and mentoring as pathways to teacher growth, (4) negotiating workload, resistance, and contextual constraints, and (5) building reflective and data-informed supervisory practices. The findings emphasize that effective instructional supervision extends beyond compliance and classroom observation. It requires professional trust, constructive feedback, differentiated technical assistance, collaborative problem-solving, and sustained monitoring of teachers' instructional needs. Based on the findings, the study proposes the Collaborative and Developmental Instructional Supervision Framework, which integrates diagnosis, observation, reflective dialogue, differentiated technical assistance, collaborative professional learning, and follow-through. The study concludes that instructional supervision is most effective when supervisors and master teachers function as instructional partners who promote continuous professional learning rather than merely as evaluators of teacher performance.
