Evidence Required

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 faultfinding 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 siterelated 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

ICTOPNA Install and test a dense wavelength division multiplexer system

ICTOPN4115A Install and test a dense wavelength division multiplexer system

ICTTENA Install configuration programs on PC based customer equipment

ICTTEN4051A Install configuration programs on PC based customer equipment

ICTTENA Install configure and test an internet protocol network

ICTTEN4198A Install, configure and test an internet protocol network

ICTTENA Install configure and test a router

ICTTEN4199A Install, configure and test a router.

Aboriginal people and other people from a nonEnglish 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
