—— Management styles and strategies are widely recognized as critical determinants of operational efficiency in organizational settings, particularly in public educational institutions where resource optimization and service delivery are paramount concerns. This study examined the management styles, management strategies, and operational efficiency of Supply Offices in selected schools in Zone 4, Division of Catanduanes, Philippines, during the School Year 2025– 2026. Specifically, it assessed the levels of management styles in terms of authoritative, democratic, and coaching approaches; evaluated the extent of management strategies implemented in terms of inventory management, standardization, and communication; determined the level of operational efficiency in terms of order frequency tracking, lead time analysis, and cost analysis; and investigated the significant relationships among these variables. Employing a descriptivecorrelational research design, the study involved 277 teaching and non-teaching personnel from five selected high schools who participated through complete enumeration. Data were gathered using a validated researcher-developed questionnaire with excellent internal consistency (Cronbach’s α = 0.94) and analyzed using weighted mean and Pearson’s product-moment correlation coefficient at 0.05 level of significance. Findings revealed that the Supply Offices demonstrated highly manifested management styles (WM=3.30), with democratic leadership emerging as the most prominent approach, followed by coaching and authoritative styles. Management strategies were highly demonstrated (WM=3.36), with communication ranking highest, followed by standardization and inventory management. Operational efficiency was highly exhibited (WM=3.27), with lead time analysis obtaining the highest rating, followed by cost analysis, while order frequency tracking, though within the demonstrated level, presented opportunities for improvement. Significant positive relationships were established between management styles and management strategies (r=0.613), management styles and operational efficiency (r=0.139), and management strategies and operational efficiency (r=0.254), indicating that effective leadership practices and sound management strategies collectively contribute to enhanced supply office performance. The study underscores that while Supply Offices maintain effective management practices and efficient operations, strategic improvements in inventory monitoring and process optimization are necessary to sustain and enhance service delivery. Anchored on Lewin’s Leadership Style Theory and Fayol’s Administrative Management Theory, the findings provide empirical evidence on the interplay between leadership behaviors, management practices, and operational outcomes in public school administrative units. Based on the findings, a Strategic Management Enhancement Framework was developed to strengthen leadership practices, improve management strategies, and enhance the operational efficiency of public secondary school supply offices. The study contributes localized empirical evidence to the growing literature on educational management and provides practical implications for strengthening administrative operations, resource utilization, and service delivery in geographically isolated and resource-constrained school contexts.
