The VET Resources / Mapping

Coverage and sufficiency are different questions

Addressing a requirement is not evidencing it.

A mapping typically shows that each requirement is addressed somewhere. What is separately required is that the assessment produces enough evidence to judge competence, across the range of conditions the requirement specifies.

Materials commonly satisfy the first and not the second. Every criterion appears; the assessment produces one instance of performance under favourable conditions, and nothing establishes consistency or range.

The requirements around range, conditions and frequency are usually stated in the unit itself and are the part most often skimmed. Reading them specifically, and checking what the assessment actually produces against them, is where sufficiency problems are found.

Foundation skills and the requirement to demonstrate them in context are another recurring gap, frequently addressed by an assertion in the mapping rather than by anything in the assessment.

Where the assessment cannot produce sufficient evidence within the delivery, that is a design constraint that has to be resolved rather than mapped around, and it is a common reason a resource fails validation.

There is a further sufficiency question that materials rarely address, which is what happens on a reassessment. A learner found not yet competent needs a second opportunity that is genuinely different rather than the same task again, and resources routinely supply one version and leave the provider to improvise the rest.
