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

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

evaluate earthing needs for cable systems on customer premises and apply related OHS requirements

determine potential earthing locations

determine earth route and support system

install functional earth installations including equi-potential bonding

test and label earth installation

manage remote power feed services.

Context of, and specific resources for assessment

Assessment must ensure:

sites where installation of functional and protective telecommunications earthing system may be conducted

use of testing equipment currently used in industry

relevant regulatory and equipment documentation that impact on installation activities.

Methods of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

review of a hands-on project completed by the candidate

review of an oral and written report with completed documentation, such as test results, updated cable plans and records

direct observation of the candidate installing a functional and protective telecommunications earthing system.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICTCMP2022B Organise and monitor cabling to ensure compliance with regulatory and industry standards.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.

Required Skills and Knowledge

Required skills

communication skills to liaise with internal and external personnel on technical and operational matters

literacy skills to interpret technical documentation, such as equipment manuals and specifications, competency requirements for telecommunications earthing systems

problem solving skills to solve equipment and logistics problems

safety awareness skills to:

apply precautions and required action to minimise, control or eliminate hazards that may exist during work activities

select and use required personal protective equipment conforming to industry and OHS standards

work systematically with required attention to detail without injury to self or others, or damage to goods or equipment

task management skills to work systematically with required attention to detail

technical skills to use hand and power tools, diagnostic equipment and perform fault clearance.

Required knowledge

ACMA Competency Requirements for Telecommunications Cabling Provider Rules 2000, legislation, codes of practice and other formal agreements that impact on the work activity
