This study aims to develop a competency model for competency-based parent education. Through conducting a comprehensive literature review, focus group interviews (FGI), and Delphi surveys, a parental competency model consisting of five competency clusters, 16 core competencies, and 40 sub-competencies was established. The model identifies five primary competency clusters: self-care, basic parenting, child education, school collaboration, and support for child independence. The self-care cluster includes self-understanding and reflection, self-management and growth, and social relationship building. The basic parenting cluster encompasses understanding children's characteristics, practicing positive parenting, and fostering a healthy family culture. The child education cluster comprises establishing an educational philosophy, providing character and life guidance, and supporting learning. The school collaboration cluster includes understanding educational policies, engaging in school activities, and collaborating with teachers. Finally, the support for child independence cluster includes promoting children's self-esteem, fostering challenge-seeking behaviors, facilitating self-directed career exploration, and nurturing social contribution awareness. This study offers a systematic framework for parental competencies, providing a robust foundation to shape future parent education programs and enhancing the practical competencies of parents.
