Underpinning skills and knowledge

Assessment must include evidence of the following knowledge and skills:

typical maintenance needs and schedules for the range of vision systems in use
cleaning agents, equipment and techniques for the major types of vision systems
interpretation of service documentation and manuals
techniques and processes for detecting faults
common repair requirements for the major types of vision systems
spare parts and sub-assemblies used in vision system repair and maintenance
connection protocols, connectors and adaptors used with vision systems
storage and maintenance and specific properties of various recording/playback mediums used in vision systems, eg computer discs, tapes, slides, video, film, servers, RAM chips
specific occupational health and safety issues and regulations in relation to the repair and maintenance of major types of vision systems

Linkages to other units

This unit has linkages to a range of other vision systems units, and combined training and/or assessment with those units would be appropriate, eg:

CUEAUD02B Prepare, rig, test and modify vision systems
CUEAUD03B Operate vision systems

Critical aspects of evidence

The following evidence is critical to the judgement of competence in this unit:

ability to correctly use repair and maintenance techniques on multiple pieces of vision systems
correct selection and use of tools
application of logical fault detection procedures
correct interpretation of service and technical manuals
knowledge of occupational health and safety principles, issues in relation to the major types of vision systems

Method and context of assessment

The assessment context must provide for:

demonstration of skills within an environment which has a range of operational equipment on which the candidate can work, including sound, lighting and projection items
completion of fault detection, repair and maintenance tasks within typical workplace time constraints

Assessment may incorporate a range of methods to assess practical skills and the application of essential underpinning knowledge, and might include:

direct observation of maintenance and repair tasks conducted by the candidate
inspection of items repaired or maintained by the candidate
review of repair reports prepared by the candidate
written or oral questioning to test knowledge of typical vision systems and occupational health and safety issues and regulations
review of portfolios of evidence and third party workplace reports of on-the job performance by the candidate
Assessment methods should closely reflect workplace demands and the needs of particular groups (eg people with disabilities, and people who may have literacy or numeracy difficulties such as speakers of languages other than English, remote communities and those with interrupted schooling).
