Evidence Guide

Evidence Guide 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

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

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge.

A person who demonstrates competency in this unit must be able to:

  • comply with WHS requirements and safe work practices
  • ensure electrical and mechanical integrity of any component and system is maintained when performing tests
  • check associated electrical components and systems of HV HEVs according to manufacturer’s specifications
  • complete relevant documentation for the service and maintenance of the HEV.

Context of, and specific resources for assessment 

Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting.

Assessment is to occur:

  • using standard workplace practices and procedures
  • following safety requirements
  • applying environmental constraints

Assessment is to comply with relevant:

  • regulatory requirements
  • Australian standards
  • industry codes of practice

Competency is to be assessed using an HEV that uses HV and LV AC/DC electrical systems. Where simulation is used an operational HEV must be included in the simulation.

The following resources must be made available for the assessment of this unit:

  • appropriate PPE
  • an operational HEV
  • manufacturer specifications for the HEV
  • testing equipment
  • full range of essential tools and equipment
  • workplace documentation.

Method of assessment 

Assessment must satisfy the endorsed Assessment Guidelines of this Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge.

Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application.

Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients.

Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.
