In addition to continuously updating their own knowledge of the subjects they teach, teachers are expected to work with multicultural classes, integrate students with special needs, be "assessment literate", work and plan in teams, assume some leadership roles and provide professional advice to parents, among other tasks. This chapter defines some of the knowledge, skills and character attributes required for effective teaching, including content and pedagogic knowledge, communication and organisational skills, and self-efficacy and motivation. The use of such data by the OECD is without prejudice to the status of the Golan Heights, East Jerusalem and Israeli settlements in the West Bank under the terms of international law.
