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!

Required Skills and Knowledge
Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Features of graphical representations include one (1) or more of the following:

limit lines

gradients (straight line graphs)

intercepts

maximum and minimum values

Graphs include one (1) or more of the following:

histograms

control charts

straight line graphs

parabolic graphs

Process improvement techniques include the following:

techniques in which error rates are mathematically calculated and recorded, including three sigma and six sigma

NOTE: This unit gives the underpinning calculation skill for these techniques and does not cover the implementation or use of three or six sigma systems
