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:

diagnose and identify faults including using fault history and ranking likely causes

plan and coordinate repair of network faults

apply enterprise escalation and outage procedures following related OHS requirements and work practices.

Context of and specific resources for assessment

Assessment must ensure:

sites on which remote diagnosis and repair of network may be conducted

use of test equipment currently used in industry

manufacturer's technical 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:

observation of the candidate performing remote diagnosis of network faults

observation of the candidate giving clear and precise instructions to staff engaged in on site repair

observation of the candidate repairing network faults

review of documentation completed by the candidate

oral or written questioning to assess required knowledge.

Guidance information for assessment

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

ICTCBL4099A Remotely locate and identify cable network faults

ICTTEN4081A Locate, diagnose and rectify faults

ICTTEN4085A Monitor, analyse and action telecommunications network alarms

ICTTEN4086A Undertake routine maintenance of the telecommunications network.

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.
