Application of the Unit
Application of the unit |
The unit includes identification and confirmation of work requirement, preparation for work, repair of emission control systems and associated components and completion of work finalisation processes, including clean-up and documentation. This unit of competence applies to the following and should be contextualised to the qualification to which it is being applied:
This unit of competence does not cover emission control systems associated with engine management systems. Work requires individuals to demonstrate discretion, judgement and problem-solving skills in managing own work activities and contributing to a productive team environment.

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:
|
Context of , and specific resources for assessment |
Application of competence is to be assessed in the workplace or simulated worksite The following resources should be made available:
|
Method of assessment |
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 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 the 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 |
