Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 Observation of workplace performance is desirable for assessment of this unit Consistency of performance should be demonstrated over the required range of workplace situations |
Context of and specific resources for assessment: | 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 questions during workplace assessment written assignments/projects Case study and scenario as a basis for discussion of issues and strategies to contribute to best practice 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 |
