common performance levels and standards

electrical and or optical properties to be measured

occupational health and safety (OHS) issues appropriate to the environment under inspection

overview of typical network topologies, switching, routing and transmission techniques

various test equipment types suitable for tests to be made

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:

inspect new installation and verify compliance against installation plans

prepare acceptance schedule and test criteria

undertake relevant acceptance tests and analysis against specified performance criteria complying with all related OHS requirements and work practices.

Context of and specific resources for assessment

Assessment must ensure:

sites where acceptance tests may be conducted

use of testing equipment currently used in industry

relevant regulatory and equipment 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 undertaking acceptance tests

review of reports and plans completed by the candidate for different scenarios and situations

oral or written questioning to assess knowledge of tests and inspections types of systems and applications

review of a completed acceptance documentation for systems and equipment prepared by the candidate including recommendations.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICTTEN5059A Commission telecommunications network equipment

ICTTEN5092A Undertake planned outage management.

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.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
