Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

CPPHSA5001 - Assess thermal performance of complex residential buildings

What evidence can you provide to prove your understanding of each of the following citeria?

Plan and organise thermal performance assessment.

  1. Need for assessing thermal performance of a residential building is clarified with client.
  2. Features of design requiring complex modelling techniques are determined and appropriate assessment strategies are identified in line with organisational procedures, software developer recommendations, and regulatory requirements.
  3. Cost of assessment is communicated to client in line with organisational procedures.
  4. Effective communication strategies are used to assist in establishing rapport with the client and in responding to client questions and concerns.
  5. Potential risks are identified and suitably managed.
  6. Computer equipment and software required for the assessment are identified and checked for serviceability.
  7. Documentation required for the assessment is obtained.
  8. Authority to proceed is obtained from client before commencing, and reconfirmed as appropriate during the assessment.
