The document discusses effective assessment practices based on research by John Hattie and Geoff Petty. It finds that self-reported grades and student expectations have the highest impact on learning. Feedback is also very important if it includes clarifying goals, positive reinforcement, and targets for improvement against explicit criteria. The document recommends strategies for effective feedback like peer and self-assessment, practice time, demonstrating meeting criteria, focusing on improvement over grades, group work, aligning formative and summative assessments, and using assessment pro-formas and learning loops. It provides criteria for differentiated assessments, feedback, and targets to support progress and literacy development.
