The third International Summit on the Teaching Profession, hosted by the Netherlands, the OECD and Education International, brings together education ministers, union leaders and other teacher leaders from high-performing and rapidly improving education systems, as measured by the OECD Programme for International Student Assessment (PISA), to discuss how teacher quality is defined and what standards are set and by whom; what systems are in place for teacher evaluation and how evaluations are conducted; and how teacher evaluation contributes to school improvement and teacher self-efficacy.
