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 in or affected by the work
• selecting methods and techniques appropriate to the circumstances
• completing preparatory activity in a systematic manner
• identification of application, purpose and operation
• application of the full repair sequence to an exhaust system as per the Range Statement relative to the qualification being sought
• conducting repair in accordance with workplace and manufacturer/component supplier requirements and specifications
• equipment is presented to customer in compliance with workplace requirements

Context of , and specific resources for assessment 

Application of competence is to be assessed in 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 removal, repair and replacement of faulty exhaust system/components
• equipment, hand and power tooling appropriate to the removal, repair and replacement of faulty exhaust system/components
• activities covering mandatory task requirements
• specifications and work instructions

Method of assessment 

Assessment must satisfy the endorsed assessment guidelines of the automotive industry's 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 not only to be satisfied under particular circumstance, but 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
