Based on the findings, a sustainability plan was proposed to strengthen sports chaperones through continuous training, mentoring, safe play monitoring, stakeholder collaboration, and institutional support from schools, PTAs, and LGUs. The study concluded that sports chaperones play a vital role in ensuring the welfare, discipline, and holistic development of student-athletes, emphasizing the importance of sustained professional development and systematic support mechanisms for long-term effectiveness
