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!

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

Plan analysis

  1. Choose analysis and descriptive tools and techniques appropriate to the nature of the information and the required outcome.
  2. Determine priority of data to be interrogated in consultation with suitably qualified people, and organise work.
  3. Reflect an understanding of the nature of the program or activity from which the data is obtained in the analysis of material.
  4. Reflect an understanding of the way in which the data is structured in the system in the analysis.
  5. Reflect the likely statistical indicators of the results in the analysis.
