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:
plan to test an optical ethernet link
select and perform a testing regime on ethernet optical transmissions
analyse and document test results
comply with all related OHS requirements and work practices.
Context of and specific resources for assessment
Assessment must ensure:
a telecommunications operations site with ethernet optical transmission system
test equipment currently used in industry.
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:
oral or written questioning of the candidate
direct observation of the candidate carrying out relevant measurements within an ethernet optical communication system
evaluation of written report prepared by the candidate outlining architecture components, testing regime and analysis of test results.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplaces and job role is recommended, for example:
ICTOPN4116A Use advanced optical test equipment
ICTOPN6129A Analyse optical transmission systems.

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.
