This toolkit provides teachers with various assessment for learning tools and activities to embed assessment into teaching and learning. It includes having students write and ask questions to assess their own learning, using comment-only marking and mid-unit assessments to provide feedback and identify misunderstandings, and employing techniques like wait-time, exemplar work, student marking, and self-assessment to actively involve students in the assessment process. The goal is to make assessment purposeful for learning and progression rather than just for grading.
