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:

methodically analyse fault details and diagnose potential faults

conduct advanced tests to determine complex network fault

isolate and locate the fault logically

rectify faults using appropriate organisational procedures and OHS requirements

comply with all related OHS requirements and work practices.

Context of and specific resources for assessment

Assessment of this unit requires:

sites on which fault diagnostics may be conducted

use of testing equipment currently used in industry

relevant regulatory and equipment documentation that impact on complex fault repairs.

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 applying safety aspects to the locating and rectifying the faults

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

evaluation of report prepared by the candidate including test result interpretation

written reports prepared by the candidate outlining fault rectification methodologies and recommendations.

Guidance information for assessment

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

ICTTEN5058A Acceptance test new systems and equipment

ICTTEN5059A Commission telecommunications network equipment

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.
