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:

identify different faults

establish context and background information and determine and rank likely causes of fault

obtain suitable tools and equipment and apply simple checks, tests and fault-finding methodology

apply recommended means to rectify fault

comply with all related OHS requirements and work practices.

Context of and specific resources for assessment

Assessment must ensure:

site where fault identification and resolution may be conducted

use of test and related equipment currently used in industry

relevant technical specifications and requirements for telecommunications networks

regulatory and site-related documentation.

Method of assessment

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

direct observation of the candidate locating and rectifying faults following OHS requirements

oral or written questioning to assess knowledge of types of faults and implications

evaluation of written reports prepared by the candidate, outlining test result interpretation, fault rectification and recommendations.

Guidance information for assessment

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

ICTOPN4115A Install and test a dense wavelength division multiplexer system

ICTTEN4051A Install configuration programs on PC based customer equipment

ICTTEN4198A Install, configure and test an internet protocol network

ICTTEN4199A Install, configure and test a router.

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 clients on technical and operational matters and raise OHS issues

literacy skills to interpret technical documentation and standards and incorporate technical language into written tasks including report on recommendation to rectify fault

numeracy skills to interpret technical data, such as specifications of equipment operations

problem solving skills to apply methodology in fault diagnosis

research skills to access technical information and sources to assist fault identification

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

technical skills to select and use appropriate methods for fault identification and rectification

Required knowledge

fault-finding techniques and test equipment

safety requirements and standards

various client's workplace environment and practices

various types of networks and equipment
