Overview of assessment |
|
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
Critical aspects for assessment and evidence are:
|
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 studies/scenarios 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:
In all cases it is expected that appropriate practical/simulation assessment will be combined with targeted questioning to assess the required knowledge, and theoretical assessment will be combined with appropriate practical/simulation 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. |
