Abstract
This study assessed the implementation of Republic Act 10121, the Philippine Disaster Risk Reduction and Management Act, within public schools in Cabadbaran City. The research addressed the effectiveness of programme execution across four thematic areas: prevention and mitigation, preparedness, response, and recovery. The study also examined the administrative capacity of school leaders responsible for disaster risk reduction and management (DRRM) functions. Using descriptive and correlational research designs, the study gathered data through survey analysis from 42 school administrators, including school heads and DRRM coordinators. Results indicated consistent implementation ratings across all thematic areas, with preparedness receiving the highest rating. School administrators demonstrated capacity in institutional planning, resource management, and community engagement. The analysis confirmed a strong positive relationship between programme implementation and administrative capacity, indicating that leadership competence supported effective disaster management. Gaps persisted in infrastructure resilience, financing, and sustained risk reduction. CONTRIBUTION: The study affirmed the need for policy integration and continued capacity development to reinforce school-based disaster risk governance.
