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: use optical power test equipment measure optical signals at three WDM wavelengths install splitter in the enclosure connect input and out optical fibres to the splitter test optical splitter complete connection recording comply with all related OHS requirements and work practices. |
Context of, and specific resources for assessment | Assessment must ensure: a telecommunications operations site where installation of optical fibre splitters in FDH may be conducted a fibre distribution hub and relevant optical splitter use of tools, equipment and personal protective equipment currently used in industry relevant regulatory and equipment documentation that impacts on work activities. |
Methods 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 candidate installing optical fibre splitters in FDH direct observation of candidate applying all related OHS requirements and work practices 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, e.g. ICTBWN3090B Install lead-in module and cable for fibre to the premises ICTBWN3100B Work safely with live fibre to test and commission a fibre to the x installation. 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. |
