EVIDENCE GUIDE
The Evidence Guide identifies the critical aspects, knowledge and skills to be demonstrated to confirm competency for this unit. This is an integral part of the assessment of competency and should be read in conjunction with the Performance Criteria, the Range Statement, and the Assessment Guidelines of the Training Package.
|

• Pre-requisite units are: BCCCM1001C Follow OH&S policies and procedures Competency in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role |
|
Specific knowledge required to achieve the performance criteria |
A knowledge of
|
|
The context of assessment |
• The application of competency is to be assessed in the workplace or realistically simulated construction site • Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints • Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context • Assessment is to comply with relevant regulatory or Australian Standards requirements |
|
Methods of assessment |
• Assessment must satisfy the endorsed assessment guidelines of the Building and Construction industry’s Civil Construction Training Package and relevant NOHSC standards where they apply • Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge • Assessment must be by direct observation of tasks, with questioning on underpinning knowledge • Assessment methods must confirm the ability to access and correctly interpret and apply the essential underpinning knowledge • Assessment may be applied under project related conditions (real or simulated) and require evidence of process • Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances • Assessment may be in conjunction with assessment of other units of competency, including those listed above |
|
Specific resource requirements for this unit |
• The following resources should be made available: - workplace location or simulated workplace - an operational tracked dozer with appropriate attachment(s) - realistic tasks covering the mandatory task requirements - maintenance materials appropriate to the dozer equipment - specifications and work instructions |
