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: rectify fault as instructed by NOC, following OHS requirements and anti-static precautions replace telecommunications hardware within service assurance guidelines according to enterprise procedures update fault records database according to enterprise procedures. |
Context of and specific resources for assessment | Assessment must ensure: suitable site to replace telecommunications network hardware range of hardware currently used in industry range of general and test equipment required for testing telecommunications network hardware. |
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 developing rectification strategy direct observation of the candidate replacing telecommunications network hardware within service assurance guidelines oral or written questioning of the candidate to assess knowledge of replacement of telecommunications network hardware practices. |
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. |
