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, assemble and install a complex digital reception system conduct functionality tests and interpret results perform handover to customer apply related OHS requirements and work practices. |
Context of, and specific resources for assessment | Assessment must ensure: site for complex digital reception system installation range of complex digital reception systems currently used in industry range of test equipment required for digital reception system installation and testing. |
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: direct observation of the candidate installing a complex digital reception system direct observation of the candidate conducting signal measurement and adjusting for optimal performance oral or written questioning of the candidate to assess knowledge of complex digital reception systems oral or written questioning of the candidate to assess knowledge of test methods and performance requirements. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTDRE4166A Integrate customer digital reception 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. |
