The Philippine Disaster Risk Reduction and Management (DRRM) are put into practice by the Department of Education (DepEd). It aimed to increase students’ degree of resilience to natural disasters by integrating Disaster Risk Reduction Management (DRRM) into the curricula and other educational programs. This study was conducted to assess the disaster preparedness and related knowledge among Senior High School students of Del Pilar National High School in Cabadbaran City. A total of 120 respondents from Grades 11 and Grade 12 were subjected to the study. An adapted and modified survey questionnaire was utilized to collect the data. A five-point Likert scale was used to evaluate the responses. The results obtained high disaster preparedness (WM- 3.88) and disaster-related-knowledge indicators (WM- 3.53) with its verbal interpretation of Prepared. This indicates a helpful indicator that the students in the study area were equipped with disaster management. While a significant correlation P< 0.0001 between age to disaster preparedness and related knowledge has been obtained. This indicates a strong relationship that age is an important factor in influencing disaster management. Further, results obtained from a high level of participants showed related knowledge, preparedness, and awareness of disasters associated with the use of effective, safe, and standardized methods. Employing the study emphasizes readiness, and resiliency while assessing the knowledge among the students in responding to the disaster. Thus, it presented information for students to improve and sustain their level of disaster preparedness to ensure safety on the school premises.
