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:

  • excavate for installation of an enclosure and conduit to industry standards applying related OHS requirements and work practices
  • install enclosure and conduit according to specifications and industry standards
  • restore site and complete documentation.

Context of , and specific resources for assessment 

Assessment must ensure:

  • sites where installation of underground enclosures and conduit may be conducted
  • use of installation equipment currently used in industry
  • relevant regulatory and equipment documentation that impact on cable installation activities.

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:

  • review of a hands-on project completed by the candidate
  • review of an oral and written report with completed documentation outlining design amendments
  • direct observation of the candidate installing underground enclosures and conduit.

Guidance information for assessment 

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

  • ICTCBL3019A Install underground cable.

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.
