The Competence-Based Curriculum (CBC) focuses on developing learners' skills and competencies, ensuring a holistic approach to education. Active parental engagement in their children's education is essential, as it not only enhances the academic success of learners but also significantly contributes to the mental well-being of parents. This study aims to explore strategies that may enhance the mental well-being of parents during CBC implementation in public day schools primary in Nairobi County, Kenya. The study adopted a qualitative design and was grounded in the theory of the Epstein model and Cognitive Behavioral Therapy. The target population comprised parents of children enrolled in public day primary schools in Nairobi County. A purposive sampling technique was employed to select a sample size of 12 participants, ensuring a representative distribution across different demographic profiles. Data was collected using in-depth interviews and subjected to thematic analysis. The findings revealed that enhancing parental support during CBC implementation requires a multifaceted approach involving workshops, accessible resources, effective communication, and collaboration from schools. Schools should provide training sessions and online materials to guide parents through the CBC framework while maintaining regular updates on curriculum changes. Additionally, parents' associations may foster community support groups and offer mental health resources, which can alleviate stress for parents. The study also emphasized the role of learners in supporting their parents through effective communication and encouraging independence, promoting a collaborative learning environment essential for the success of CBC.
