This study delved into the challenges faced by members of Lupong Tagapamayapa in performing their duties and responsibilities. The research included two participant groups: the members of the Lupong Tagapamayapa and the complainants who filed cases from January 2018 to December 2019 in selected barangays of the third district of Cagayan. The challenges were identified using a focus group discussion. Findings indicate that the main problem they encounter is the non-appearance of respondents. Disrespect to authority and the lack of regular training seminars and meetings also contribute significantly to the difficulties experienced. The least encountered problems were bias decision making and tardiness of parties during confrontations. In response to these issues, the research proposes a comprehensive training program titled “Proposed Training Program for Lupong Tagapamayapa on the execution of the Katarungang Pambarangay Law”. This one-year program, aimed at Lupong Tagapamayapa members in the three most populated barangays of the Third District of Cagayan, is designed to conduct a series of seminars, workshops, and training sessions on the KP Law and dispute resolution processes. It also includes a KP Education Campaign Drive for all the residents of the barangay. The program will be facilitated by content and process experts, and its progress will be tracked through quarterly monitoring, providing valuable data for the continual improvement and expansion of the training program. By addressing these identified issues, this training program aims to enhance the efficacy of Lupong Tagapamayapa, thereby improving local dispute resolution mechanisms and the overall peace and order situation in barangays.
