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!

Instructions to Assessors

Required Skills and Knowledge

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least two separate occasions and include:

applying relevant work, health and safety (WHS)/occupational health and safety (OHS) requirements, including using risk control measures

applying safe working practices and relevant industry standards, codes of practice and regulations

applying sustainable energy principles and practices

completing work documentation and reporting requirements

dealing with unplanned events/situations in accordance with workplace procedures in a manner that minimises risk to personnel and equipment

determining the basic operating conditions of an air conditioning systems, including the air dry and wet bulb temperatures, relative humidity, air velocity and volume flow rates across a grille/register and documenting operating conditions

identifying operating parameters not within specified range of the air conditioning system

interpreting measurements

selecting and using appropriate measuring devices

using calculation methods accurately.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions and include knowledge of:
