In the context of this unit standard, understanding means that there should be
evidence of a learners’ thorough comprehension of a topic. A learner with a good
understanding of a topic should have applied, or should be able to apply what they
have learnt to a workplace situation and will be able to alter their practices to the
different contexts they are applying their learning to. Assessors should be confident
that the learners’ understanding is embedded in their practices and behaviour.
