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, range statement and the Assessment Guidelines for the Training Package. |
|
Overview of assessment |
This unit of competency could be assessed in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
|
Context of and specific resources for assessment |
This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints. Assessment of essential underpinning knowledge will usually be conducted in an off-site context. Assessment is to comply with relevant regulatory or Australian standards' requirements. Resource implications for assessment include:
Assessment of this unit of competency may be in conjunction with assessment of other units commonly performed at the same time in normal job roles. Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support. |
Method of assessment |
Assessment methods must:
Validity and sufficiency of evidence requires that:
Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed. Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff. |
