Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Critical aspects for assessment and evidence required to demonstrate this competency unit:

The individual being assessed must provide evidence of specified essential knowledge as well as skills

Where, for reasons of safety, space, or access to equipment and resources, assessment takes place away from the workplace, the assessment environment should represent workplace conditions as closely as possible

Consistency of performance should be demonstrated over the required range of situations relevant to the workplace

Context of and specific resources for assessment:

Relevant organisation policy, guidelines, procedures and protocols

Method of assessment:

Clinical skills involving direct client care are to be assessed initially in a simulated clinical setting (laboratory). If successful, a second assessment is to be conducted during workplace application under direct supervision.

Observation of work activities when performing polysomnographic recordings

Observation of simulation and/or role play when performing polysomnographic recordings

Discussion of physical and/or behavioural contingency scenarios involving duty of care

Authenticated transcripts of relevant education/training courses
