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 | This unit of competency could be assessed by candidates collecting and analysing information on the costs of measures for improving the thermal performance of a residential building based on the outcomes of a NatHERS assessment of potential options. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | A person should demonstrate the ability to: identify potential measures for improving the thermal performance of residential buildings gather information on costs of measures for improving thermal performance of residential buildings analyse costs of measures for improving thermal performance of residential buildings identify limitations of cost information. |
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 include: computer equipment suitable for producing reports for clients technical reference library with current publications on energy efficiency materials, products and services. |
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: written and/or oral assessment observed, documented and/or first-hand testimonial evidence of the candidate collecting and analysing information on the costs of measures for improving the thermal performance of a residential building based on the outcomes of a NatHERS assessment of potential options. |
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. |
