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:
verify 'as built' installation against installation plans
undertake acceptance and commissioning tests and analysis against specified performance criteria
complete report, including acceptance test procedures, results and recommendations
comply with all related OHS requirements and work practices.
Context of and specific resources for assessment
Assessment must ensure:
sites on which 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
oral or written questioning to assess knowledge of tests and inspections types of systems and applications
review of 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 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.
