Evidence Guide

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, required Skills and Knowledge, the 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	The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge. A person who demonstrates competency in this unit must be able to: observe safety procedures and requirements select methods and techniques appropriate to the circumstances complete preparatory activity in a systematic manner diagnose and repair a range of heavy trailer roll stability systems diagnose and repair heavy trailer roll stability systems according to workplace, manufacturer and component supplier requirements present vehicle in a condition that complies with workplace requirements.
Context of, and specific resources for assessment	Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting. Assessment is to occur: using standard workplace practices and procedures following safety requirements applying environmental constraints. Assessment is to comply with relevant: regulatory requirements Australian standards industry codes of practice. The following resources must be made available for the assessment of this unit: workplace location or simulated workplace heavy trailer with roll stability faults relevant to the qualification being sought equipment appropriate for the testing of heavy trailer roll stability systems specifications and workplace instructions tools appropriate for the repair, replacement and adjustment of heavy trailer roll stability systems.
Method of assessment	Assessment must satisfy the endorsed Assessment Guidelines of this Training Package. Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge. Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application. Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role. Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients. Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.
