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

An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.

There must be evidence that the individual has installed rigging equipment and controlled at least six loads from an aerial location to the drop zone using ropes, knots and rigging system appropriate for the load dimensions and mass.

There must also be evidence that the individual has:

confirmed work instructions and location of worksite

identified site hazards, assessed risks and confirmed controls with supervisor including:

selected, checked and used appropriate personal protective equipment

confirmed the availability of first aid and emergency equipment, personnel and procedures

implemented workplace health, safety, environmental and traffic control measures

contributed to tree assessment process by assessing trees for defects

checked and removed defective equipment from service

monitored rigging system, work team movements and environmental conditions for safe work conditions
