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: conduct tests on international roaming capability and functionality of handset enhancements analyse results of testing make recommendations based on test results. |
Context of and specific resources for assessment | Assessment must ensure: site where tests on handsets and international roaming agreements may be conducted testing equipment currently used in industry equipment, system manuals, specifications and relevant enterprise policy and 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 conducting international roaming agreement tests review of report prepared by the candidate outlining findings, interpretation of test results and recommendations oral or written questioning of the candidate to assess knowledge of handsets and handset enhancements. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplaces and job role is recommended, for example: ICTRFN5148A Test and measure cellular phone and network equipment performance. 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. |
