Evidence Required

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

Critical aspects for assessment and evidence are

tyre injury is identified and appropriate action for repair determined

consistent application of repair standards

safety procedures are always followed

Context of and specific resources for assessment

Assessment will occur on an HOTR tyre repair facility Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation A bank of case studiesscenarios and questions will also be required to the extent that they form part of the assessment method Questioning may take place either in the workplace or in an adjacent quiet facility such as an office or lunchroom No other special resources are required

Method of assessment

Competence in this unit may be assessed

by observation over a range of tyre repair procedures undertaken in the workplace

in a situation allowing for the generation of evidence of the ability to respond to problems

by using a suitable simulation andor a range of case studiesscenarios

through a combination of these techniques

In all cases it is expected that appropriate practicalsimulation assessment will be combined with targeted questioning to assess the required knowledge and theoretical assessment will be combined with appropriate practicalsimulation or similar assessment

Guidance information for assessment

Assessment processes and techniques must be appropriate to the language competency and safety requirements of the site and consistent with workplace systems or procedures

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.

reporting problems outside area of responsibility/ability to designated person

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.
