Assessment for Teaching is a comprehensive and practical introduction to assessment and learning in primary and secondary school settings. This book treats assessment as a source of data that informs teaching strategies. It replaces a deficit model of assessment with a development model: a framework which recognises the importance of identifying what the student is ready to learn. The book also promotes collaboration between teachers in professional learning teams - encouraging the sharing of assessment data and team-based interpretation - to improve student outcomes and to plan goals for students based on a development scale. Each chapter contains: * an exercise for applying the course content to classroom practice * a response template for the exercise * guidelines on assessing the value of the exercise in a professional learning team * a short test for participants to cross-check their understanding of the course content. This is an essential resource for both pre-service and in-service teachers.
