This book summarises the findings on teacher appraisals presented at the third International Summit on the Teaching Profession. In some countries the concept - not to mention the use - of teacher appraisal sparks discussion whenever it is mentioned. According to what criteria? Who decides? And what should the results of teacher appraisals be used for? But education stakeholders are beginning to find some agreement in the idea that teacher appraisal can be a key lever for focusing more on teaching quality and continuous professional development for teachers, in keeping with the growing recognition that the quality of teaching affects student learning outcomes.
