In Sunday Catechism, the Parent-Teacher Association (PTA) plays an essential role in bridging the efforts of parents and teachers to provide holistic faith formation for children. The PTA actively supports catechism by fostering close cooperation between families and the parish catechism team, ensuring that Christian values taught in class are also nurtured at home. It assists in planning and organizing catechism-related activities such as exams, cultural programs, retreats, and annual gatherings, while also offering feedback and suggestions to improve the quality of catechesis. By creating a spirit of collaboration and shared responsibility, the PTA helps build a strong faith community where children grow in knowledge, discipline, and spiritual maturity under the joint guidance of parents, teachers, and the Church.
