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 

It is essential that competence is fully observed and there is ability to transfer competence to changing circumstances and to respond to unusual situations in the critical aspects of:

• observing safety procedures and requirements
• communicating effectively with others involved or affected by the work
• selecting methods and techniques appropriate to the circumstances
• completing preparatory activity in a systematic manner
• cleaning, testing, inspecting and evaluating components of units
• overhauling units, including dismantling and reassembling units to manufacturer/component supplier requirements
• repairing/replacing component parts to manufacturer/component supplier requirements
• testing final product for return to service
• completing workplace and equipment documents.

Context of , and specific resources for assessment 

Application of competence is to be assessed in the workplace or simulated worksite.

Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints.

Assessment is to comply with regulatory requirements, including Australian Standards.

The following resources should be made available:

• workplace location or simulated workplace
• material relevant to the overhaul of charging system alternators
• equipment, hand and power tooling appropriate to the overhaul of charging system alternators
• activities covering mandatory task requirements
• specifications and work instructions.

Method of assessment 

• Assessment must satisfy the endorsed Assessment Guidelines of AUR12 Automotive Industry RS&R Training Package
• Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge
• Assessment must be by direct observation of tasks, with questioning on underpinning knowledge and it must also reinforce the integration of key competencies
• Assessment may be applied under project related conditions and require evidence of process
• Assessment must confirm a reasonable inference that competence is able to be under the particular circumstance, and is able to be transferred to other circumstances
• It is preferable that assessment reflects a process rather than an event and occurs over a period of time to cover varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other persons subject to agreed authentication arrangements
• Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role
