Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the ability to:

demonstrate methodical approach to fault identification
interpret test results
repair fault and test to verify outcomes
document fault, including nature, location, likely causes and repair methodology.
Context of, and specific resources for assessment
Assessment must ensure:

site for locating and rectifying DRE faults
range of DRE currently used in industry
range of test equipment required for DRE 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 performing diagnostic tests
direct observation of the candidate locating and rectifying DRE faults
oral or written questioning of the candidate to assess knowledge of DRE and test methods and repair methodology.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICTDRE3156B Install 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.
