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
conducting the alignment of a range of wheels in accordance with workplace and manufacturer/component supplier requirements
accurately interpreting wheel alignment measurements
completing wheel alignment 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, equipment, material and personal safety requirements
operating principles of steering geometry and wheel alignment
wheel alignment procedures
relationships between fault symptoms and component defects
chassis alignment checks
wheel alignment system types and their construction
use of measuring tools and testing equipment
use of hand tools and specialised equipment
pre-check 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
