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 is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:

locates and applies relevant legislation, documentation, policies and procedures

works effectively with others to undertake and complete conducting of down-hole hammer drilling that meets all of the required outcomes including:

uses a range of communication techniques and strategies to communicate and coordinate information and activity to other

communicates the hazards of cuttings in the return air stream to all crew members

demonstrates completion of conducting down-hole hammer drilling that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:
