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: plan and monitor IP networks for performance and reliability evaluate, design and implement a troubleshooting structured plan use network testing and monitoring tools produce a maintenance plan for monitoring routing protocols and configurations implement tests of advanced network solutions. |
Context of and specific resources for assessment | Assessment must ensure access to: site where complex network installation may be conducted hardware and software organisational guidelines computers LAN and WAN systems, including voice and video hardware and software appropriate learning and assessment support when required modified equipment for people with special needs. |
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 installing, configuring and testing a new or updated network evaluation of documentation prepared by the candidate outlining testing procedures, test results, recommendation to network changes and completion records verbal or written questioning of required knowledge. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
