Evidence guide
The Evidence Guide identifies critical aspects, knowledge and skills to be demonstrated to confirm competence for this unit. This is an integral part of the assessment of competence and should be read in conjunction with the Range Statement.
|
|
|
| Critical aspects of evidence |
|
- 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, in particular, the dangers associated with handling refrigerants
- 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 operating principles
- conducting inspection, servicing and operational testing in accordance with workplace and manufacturer/ component supplier specifications
- performance testing air conditioning systems
- accurately interpreting performance test results
- conducting service operations according to industry codes of practice, legislation and manufacturer/ component supplier requirements
- completing servicing of air conditioning systems and associated components within workplace timeframes
- vehicle/equipment is presented to customer in compliance with workplace requirements
|
| Relationship to other units |
|
- Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role
|
| Underpinning knowledge |
|
- A working knowledge of:
- OH&S regulations/requirements, licence requirements, equipment, material and personal safety requirements
- dangers associated when working with refrigerants
- identification of application, purpose and operating principles
- refrigerant types and application
- system electrical circuits
- refrigerant/oils and capacities
- types and layout of service/repair manuals (hard copy and electronic)
- servicing procedures
- work practices in relation to preventing damage to sensitive electronic components
- system performance testing procedures
- enterprise quality procedures
- work organisation and planning processes
|
| Context of 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
|
| 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 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
