Teacher competency frameworks comprise a number of competencies that enable a teacher to develop effective teaching practices. However, their conception, value, use and recognition vary widely. Equally, assessment and measurement of such competencies differ across contexts. More recently, a body of research has emerged which focuses the lens of teacher preparation on the inclusion of high leverage practices. The focus of this study is to report a synthesis of the literature pertaining to the 'core competencies' and 'high leverage practices' selected for inclusion in teacher preparation. A systematic review of the literature was conducted in order to synthesis available evidence. Results are presented in two sections; competency-based approaches; and high leverage practice approaches in teacher preparation. Findings are discussed from the perspective of epistemological and methodological questions emerging from the research and the implications for teacher preparation.
