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 fault-finding 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 site-related 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: ICTOPN4115A Install and test a dense wavelength division multiplexer system ICTTEN4051A Install configuration programs on PC based customer equipment ICTTEN4198A Install, configure and test an internet protocol network ICTTEN4199A Install, configure and test a router. 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. |
