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
accurately interpreting test results
identification of application, purpose and operating principles
conducting inspection, servicing and operational testing in accordance with workplace and manufacturer/component supplier specifications
completing work within the agreed timeframe
vehicle/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 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
The following resources should be made available:
workplace location or simulated workplace
material relevant to inspection and servicing of emission control systems
equipment, hand and power tooling appropriate to inspection and servicing of emission control systems
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 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
