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!

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. To be deemed competent the candidate must be assessed in a minimum of one type of sample preparation and minimum of three of the types of complex tests from either the wastewater or drinking water options listed in the Range of Conditions. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.

comparing sample description with the specification, record results and report discrepancies

adopting hygienic work practices

limiting hazards and contamination to self, work area and environment

producing laboratory reports and logs

using laboratory safety equipment and personal protective equipment

interpreting laboratory test methods

interpreting policies, procedures and standards

interpreting and recording test results, including calculation of results from test data where required

using potentiometric, ion selective, spectrophotometric, volumetric and gravimetric laboratory equipment

performing sub-sample and testing products

labelling samples for testing
