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

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.

Major traction drive components include the following:

alternator

generator

drive shaft from engine

cooling grid/s

inverters

rectifiers

wheel motors

blowers/fans

Actions to rectify faults include one (1) or more of the following:

on-site repair, including in an on-site workshop

removal of component to a specialist off-site repair facility

referral of the fault to other trade, technical or professional personnel for rectification
