Physical evidence of a person’s competency is required for an assessor’s decision-making process. Evidence needs to be substantiated as the work of the candidate; it has to provide sufficient samples to make a valid decision; and it has to be collected in a timely manner. A high-quality assessment instrument will help to produce better quality evidence for the assessor to evaluate.
Additionally, the processes that support the collection of evidence need to be sound. This means that instructions must be clearly understood by the assessor and candidate; the collection of the evidence must be handled in accordance with storage and privacy policies; and the process must be under continuous review to ensure a high-quality system.
The definition of an assessment toolin the national standards is that assessment tools are the instrumentsand proceduresused to gather and interpret evidence of competence. The instrumentsare the activities or specific questions used to assess competence by the assessment method selected. Proceduresare the information or instructions given to the candidate and the assessor about the way the assessment is to be conducted and recorded.
