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. The candidate must be assessed in both types of sampling processes and at least two types of field tests 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.

conducting hazard and risks assessments

planning working activities

applying procedures and standards

performing task-related calculations

maintaining a safe work environment

using automatic samplers and flow measurement equipment

using recording equipment (i.e. pH or temperature recorder) and field test kits

conducting trade waste tests on-site according to specifications

disposing of waste and spent samples

identifying which parameters can be analysed in-field and which need laboratory testing

identifying necessary equipment and resources for sampling and testing (i.e. field test kits, preservation reagents)

selecting appropriate sample jars and preparing documentation (labels, chain of custody and other required forms, i.e. inspection sheets)

installing sampling, flow measuring (if applicable) and recording equipment in accordance with manufacturers’ specifications and site specific conditions

applying labels to samples and prepare appropriate documentation for external analyses
