Teacher Evaluation, Teacher Effectiveness and School Effectiveness: Perspectives from the USA

This article provides historical overviews of the conceptual and research and development focus of teacher evaluation, teacher effectiveness and school effectiveness research in the USA. Pertinent literature is cited and arguments are made that these lines of inquiry have coexisted for nearly four without adequate integration. With the fourth stage of school effectiveness research in process, there is a recognition that within school context variables, particularly teacher effectiveness, have important effects on school improvement and school outcomes. Similarly, there is the recognition that findings from school effectiveness research have relevance for studies of teacher effectiveness and ongoing developments in teacher evaluation. Examples of: (a) new generation, learner-centered teacher evaluation systems in the USA that are informed by teacher and school effectiveness research; and (b) the fourth stage of school effectiveness research are described. It is proposed that these lines of research should be merged as completely as possible.
