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:
test telecommunications networks to identify faults
identify and rectify recurrent faults
conduct and report on a fault-finding task in a telecommunications network for a range of faults
use systematic and logical fault-finding techniques in telecommunications networks and field testing procedures to particular workplace situations
comply with all related OHS requirements and work practices.
Context of and specific resources for assessment
Assessment must ensure:
sites on which network testing and fault-finding may be conducted
use of line transmission, optical and radio measurement equipment currently used in industry
system documentation, and other site-related documentation necessary to conduct tests and fault-finding investigations.
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 undertaking network tests and fault-finding techniques
review of the candidate's evaluation of network testing and fault diagnosis
oral or written questioning to assess knowledge of performance of telecommunications networks.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
ICTTEN3056A Install 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.
