This resource is one of a series of OECD Education Working papers disseminating the results of studies to a wider readership. Here the focus is on analysing current practices regarding teacher evaluation together with a review of recent literature. The field examined covers both primary and secondary sectors. The study begins with a survey of the key features of teacher evaluation schemes in use and then proceeds to a more discursive and comparative approach looking at the challenges, advantages and effectiveness of the different schemes. Both quantitative and qualitative methods are employed to reach conclusions which provide a general overview as well as recommendations for future development.
