The main purpose of this study was to examine the relationship between school facilities conservation and physical organizational resources in public elementary schools. A non-experimental quantitative research design utilizing the correlational method was employed. The respondents of the study consisted of 137 public elementary school teachers selected through universal sampling. Data were analyzed using mean, Pearson r, and regression analysis. Findings revealed that the level of school facilities conservation in terms of cleanliness, beautification, lighting, water, and ventilation was moderate. In contrast, the level of physical organizational resources, including classrooms, offices, clinics, canteens, libraries, and comfort rooms, was found to be high. Results further indicated a significant relationship between school facilities conservation and physical organizational resources. Additionally, the domains of school facilities conservation were found to significantly influence the availability and quality of physical organizational resources in public elementary schools. These findings suggest that the Department of Education (DepEd) should strengthen initiatives that enhance the involvement of both parents and teachers in sustaining facilities conservation and improving organizational resources, thereby fostering a more conducive and collaborative school environment.
