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 in this unit signifies ability to transfer competence to changing circumstances and to respond to unusual circumstances 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 diagnosis in accordance with workplace and manufacturer/component supplier requirements
interpreting and documenting the test results
completing the inspection ,repair and diagnosis of alternative fuel systems within workplace timeframes
vehicle presentation 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 and Gas Industry Standards.
The following resources should be made available:
workplace location or simulated workplace
materials relevant to the inspection, repair and diagnosis of alternative fuel systems
equipment, hand and power tooling appropriate to the inspection, repair and diagnosis of alternative fuel system for heavy vehicle engines
activities covering the 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 (real or simulated) 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 assessment reflects a process rather than an event and occurs over a period of time to cover the varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other appropriate 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.
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.
