The purpose of this paper is to investigate the beginning teachers' perceptions of pedagogical knowledge and skills in teaching in Singapore. Data was collected from the beginning teachers at three time points: the exit point of the teacher education programme, the end of their first year and third year of teaching. In this three year study, the focus is to examine the beginning teachers' perceptions of their development in the following teaching related factors: lesson planning, classroom management and instructional strategies. The results showed that beginning teachers' pedagogical knowledge and skills increased significantly, but at different rates, in all three factors at the end of their third year of teaching. It suggested that learning to teach is an on-going process that begins from the pre-service teacher education programme and continues into the initial three years of teaching. (Contains 5 tables.)
