This study investigated changes in beginning teachers' self-perceptions of their pedagogical knowledge and skills after their first year of teaching. Surveys were administered to 322 graduating student teachers at the end of the initial teacher preparation programme and at the end of their first year of teaching to compare if there were any differences in their self-perceptions. The results of the study showed significant increases in beginning teachers' perceptions of their pedagogical knowledge and skills in three factors: Instructional Support, Accommodating Diversity and Classroom Management. Results established the development of teachers to be an ongoing process that is initiated but not completed in initial teacher preparation. Implications of findings for induction and mentoring of beginning teachers are discussed.
