The main purpose of the study was to explore the extent to which Religious Education moulds behaviour among secondary school learners. The study used a qualitative approach and it followed a case study design of one school in the Namugoona Parents School, Kampala. A purposive sampling technique was used to select a sample of participants comprising of Christian Religious Education (CRE) teachers and learners, parents and other stake holders. The study revealed that learners were aware of the Christian based Religious Education and that the learners believed that Christianity teaches them good morals. Teachers on the other hand were of the view that CRE was not enough as a tool in molding learners’ behavior but should be supplemented with other factors such as parental guidance, religious leaders and the government intervention. The study concluded that teachers need to be trained in CRE competences. It was recommended that schools should foster the cooperation between teachers and parents in molding learners’ behavior through active parental involvement initiatives
