The main purpose of the study was to explore the extent to which Religious Education moulds behaviour among primary school learners. The study used a qualitative approach and it followed a case study design of one school in the Manzini urban area of Eswatini. A purposive sampling technique was used to select a sample of participants comprising of Christiamn Religious Education (CRE) teachers, and grade seven learners. 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 moulding learners’ behaviour. 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 moulding learners’ behaviour through active parental involvement initiatives. It was proposed that the INSET department should ensure proper training is given to CRE teachers so that they are an effective tools in implementing the CRE syllabus for effective harnessing of positive behaviour.
