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:

Assessment should replicate workplace conditions as far as possible

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

Resources essential for assessment include access to:

relevant workplace or appropriately simulated environment where assessment can take place

Australian Standards, government and organisation policies and procedures

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

This describes the essential skills and knowledge and their level required for this unit.
