My field of research and scholarship is the evaluation of educational effectiveness, whether of teachers, schools or educational systems. My major contributions to knowledge in the field are in three distinct but related dimensions. These are the evaluation of teacher effectiveness, the evaluation of school effectiveness, and the development of generic and differential models of educational effectiveness that can be used for establishing links between research and improvement of policy and practice. Currently my research agenda is concerned with the development of a dynamic model of educational effectiveness, and the application of effectiveness research to the improvement of educational practice.
