This report provides an account of the development of a set of assessment heuristics. The aim of the assessment heuristics is to aid curriculum developers and instructors in their thinking and assumptions about assessment in the contexts of work, and work-based and/or work-place learning. The assessment heuristics may also be used to create dialogues among stakeholders about the writing of (assessment) standards, accreditation processes, and curriculum and assessment design. Included in this report are findings of one workshop and two focus group discussions (FGDs) where participants tested and validated the assessment heuristics. These activities generated insights into assessment of, for and as learning, and highlighted opportunities for intervention and change in key areas of assessment as well as provisions for further improvement of the assessment heuristics.
