School peer reviews are designed to support learning and development in participating schools, with the aim of improving the quality of teaching and learning. The process, which takes place over a set number of days, is a cooperative partnership between a review team and a host school. Teacher peers provide useful feedback through observation and interactions at the host school. The overview document sets out the purpose, principles and scope of a peer review process, including a description of the four domains and the three phases of the process. The Peer Review Process has links to 12 supporting tools and resources for planning, implementation and feedback.
