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!

MSL973023 - Perform fire pouring techniques

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

Plan work for shift

  1. Review job requests to identify the samples, preparation methods required for each, and shift priorities
  2. Identify hazards, safety equipment/procedures associated with samples, preparation methods, reagents and equipment
  3. Plan parallel work sequences to optimise the throughput of multiple sets of samples during shift
  4. Assemble all required equipment, materials, reagents and check they are fit for purpose
  5. Check pots and cupels and discard those with faults and/or a record of high gold values
  6. Check that fusion and muffle furnaces are operating at the specified temperatures
