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

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

Context of and specific resources for assessment:

Simulations may be used to represent workplace conditions as closely as possible

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

Method of assessment

Evidence of essential knowledge and understanding may be provided by:

traditional or online (computer-based) assessment

written assignments/projects

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

Questioning

Staff and/or client feedback

Supporting statement of supervisor

Authenticated evidence of relevant work experience and/or formal/informal learning

Role play/simulation

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
