Assessment tools are intricate pieces of VET machinery. Its component parts include describing the conditions in which assessment occurs, specification of assessment tasks, and clear statements about the evidence to be collected and the performance benchmarks to be applied. Assessment tools also record assessment outcomes. In this webinar, Sarah Phillips strips down an assessment tool into its component parts. We examine the function of each part, and how to assemble a working version that supports teachers to fulfil their responsibilities, is clear to students, and meets audit expectations.
