Context of and specific resources for assessment | Assessment of this unit: must be in the context of the work environment may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills must meet relevant compliance requirements. Resource implications for assessment may include: work location for renovation activity tools, plant and equipment appropriate to renovation and replacement processes construction materials relevant to the activity documentation relevant to task scaffolding appropriate to location and activity. |
Method of assessment | Assessment for this unit must verify the practical application of the required skills and knowledge, using one or more of the following methods: direct observation of tasks in real or simulated work conditions questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application review of relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff. |
Guidance information for assessment | This unit could be assessed on its own or in combination with other units relevant to the job function. 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. 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. |
