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

Evidence Guide

What evidence is required to demonstrate competence for this standard as a whole?

Competence in sampling and testing water quality requires evidence that water quality has been appropriately sampled and tested for a given site according to prescribed scientific procedures, standards and principles, monitoring schedules and industry best practice. The skills and knowledge required to sample and test for water quality must be transferable to a range of work environments and contexts. For example, this could include different locations, environments and monitoring schedules.

What specific knowledge is needed to achieve the performance criteria?

Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts and to deal with unplanned events. The knowledge requirements for this unit are listed below:
