The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for this Training Package.

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 a diagnostic sleep study

Observation of simulation and/or role play when an performing a diagnostic sleep study

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

Authenticated transcripts of relevant education/training courses

Recognition of relevant life/work experience

Questioning, written assessments/projects, e-learning can be used to assess knowledge

Authenticated reports of experience in performing a diagnostic sleep study (Documentation associated with performance reviews, supervisor/co-ordinator evaluations of work performance)

Training records associated with First Aid, OH Safety training, Orientation/Induction Training, Safe Manual Handing, Universal infection control procedures

Case study and scenario as a basis for discussion of issues and strategies to contribute to best practice

Access and equity considerations:

All workers in the health industry should be aware of access and equity issues in relation to their own area of work

All workers should develop their ability to work in a culturally diverse environment

In recognition of particular health issues facing Aboriginal and Torres Strait Islander communities, workers should be aware of cultural, historical and current issues impacting on health of Aboriginal and Torres Strait Islander people

Assessors and trainers must take into account relevant access and equity issues, in particular relating to factors impacting on health of Aboriginal and/or Torres Strait Islander clients and communities

Related units:

This unit should be assessed in conjunction with the following related units:

HLTSL401C Prepare environment to perform sleep studies

HLTSL402C Prepare client for sleep study procedure

HLTSL404C Perform treatment sleep study

Holistic assessment practice with other health services units of competency is encouraged
