EVIDENCE GUIDE
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.
