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 inspected at least six trees, each with a client specified scope of works for access and tree work, and where:

at least 1 tree is inside the safe approach distance of power lines

at least 2 trees have defects and hazards that will require additional controls specified in the scope of works

at least 2 trees have defects and hazards that require a change in the work method specified in the scope of works

at least 1 tree is within the specifications for the scope of works.

There must also be evidence that the individual has for each of the six trees:

confirmed access to site and identified tree and scope of works

completed a job safety analysis documenting site-specific items including:

work health, safety and environmental hazards

risks that were not controlled by the organisational Safe Work Method Statement (SWMS)

risk control measures

identification of overhead and underground services and approach distances

use of personal protective equipment

inspected tree for structural defects, disease, insects, fauna and other considerations in trunk, roots and branches that may impact tree access or work

selected an appropriate tree access or tree work method, considering:

the scope of works required

site and tree hazards identified

limitations imposed by crew skill level and resources available

informed work team of hazards and control measures to implement during access and tree work

documented control measures, and tree access and work method according to workplace procedures

advised stakeholders where tree works were altered or rescheduled according to workplace procedures.

All tree inspection work is required to be performed according to preferred industry practices (as outlined in the Companion Volume).

An individual must be able to demonstrate the knowledge required to perform the tasks outlined in the elements and performance criteria of this unit. This includes knowledge of:
