The Essential Guides for Early Career Teachers provide accessible, carefully researched, quick-reads for early career teachers, covering the key topics they will encounter during their training year and first two years of teaching. This title provides a range of practical but critically engaged strategies and approaches to assessment. It offers a brief history of the core ideas and educational philosophy underpinning these, looks at links to planning and reflection, examines the concept of progress over time as a mirror for quality teaching and learning, and explores the idea of pupil self-assessment. Most importantly, it recognizes that assessment can and should be at the heart of enabling and accelerating the progress of all learners.
