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
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 full repair sequence as per the Range Statement to an emission control system relative to the qualification being sought
interpreting test results
conducting repair in accordance with workplace and manufacturer/component supplier requirements
vehicle/equipment presentation 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

Specific key competencies, underpinning and employability skills required to achieve the performance criteria
These include a number of processes that are learned throughout work and life, which are required in most jobs. Some of these are covered by the national key competencies, although others may be added. The details below highlight how these competencies are to be applied in the attainment of this unit.

Application of the key competencies in this unit are to satisfy the nominated level in which:

Level 1 - relates to working effectively within set conditions and processes;
Level 2 - relates to management or facilitation of conditions or processes; and
Level 3 - relates to design, development and evaluation of conditions or process.
How will the candidate apply the following key competency in this unit? The candidate will need to:

Collect, analyse and organise information
Apply research and interpretive skills sufficient to locate, interpret and apply manufacturer/component supplier procedures, workplace policies and procedures
Apply analytical skills for identification and analysis of technical information
(Level 2)

Communicate ideas and information
Apply plain English literacy and communication skills in relation to dealing with customers and team members
Apply questioning and active listening skills for example when obtaining information from customers
Apply oral communication skills sufficient to convey information and concepts to customers
(Level 1)

Plan and organise activities
Apply planning and organising skills to own work activities, including making good use of time and resources, sorting out priorities and monitoring own performance
(Level 2)

Work with others and in a team
Interact effectively with other persons both on a one-to-one basis and in groups, including understanding and responding to the needs of a customer and working effectively as a member of a team to achieve a shared goal
(Level 1)

Use mathematical ideas and techniques
Use mathematical ideas and techniques to correctly calculate time, assess tolerances, apply accurate measurements, calculate material requirements and establish quality checks

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

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
