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: apply knowledge of WiMAX communication architecture, hardware, protocols and networking systems integrate other wireless technologies analyse and evaluate competing wireless technologies design viable WiMAX network solutions assess network performance. |
Context of and specific resources for assessment | Assessment must ensure: documents detailing: IEEE 802.16 standards for WiMAX client requirements technical specifications expected traffic volume vendors and vendor offerings and pricing information on a range of IT business solutions future organisational business processes budget for architecture designs for WiMAX networks. |
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 assessing network requirement evaluation of implementation document prepared by the candidate outlining WiMAX architecture designs oral or written questioning of the candidate to assess knowledge. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTTEN6206A Produce an ICT network architecture design ICTTEN5204A Produce technical solutions from business specifications. 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. |
