Conduct the fault rectification, if the customer agrees, in a manner which is safe to the repair team and the customer 3.4. Escalate any unresolved faults to other parties for resolution if required |
4. Complete documentation and clean up worksite | 4.1. Advise the customer of successful fault clearance and obtain sign off 4.2. Complete all records 4.3. Complete reports to justify the fault diagnosis and rectification methodology if required 4.4. Remove all waste and debris from worksite and dispose of according to environmental requirements 4.5. Restore any changes made to the worksite during fault repair to the client's satisfaction |

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 using simple checks, tests and fault-finding methodology determine and rank likely causes of fault provide fault rectification solutions to customer rectify faults escalate unresolved faults to other parties for resolution comply with all related OHS requirements and work practices. |
Context of, and specific resources for assessment | Assessment must ensure: sites where cable system tests may be conducted use of fault-finding equipment currently used in industry relevant regulatory and equipment documentation that impact on cable system testing and fault-finding 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: review of a hands-on project completed by the candidate review of an oral and written report, including test results and fault-finding methodologies direct observation of the candidate locating and identifying cable system faults. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTCBL2016A Joint metallic conductor cable on customer premises. 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. |
