This research uses a descriptive qualitative approach with a case study method, collecting data through in-depth interviews, observations, and document analysis involving teachers, parents, and school staff. Findings indicate the partnership has been well established, marked by intensive communication and joint activities supporting character building. However, challenges include differing levels of parental participation, time constraints, and lack of coordination in some activities.
