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:

plan the installation of a WAN accessible network

select and apply WAN link protocols

configure IP addressing across the WAN

troubleshoot WAN communication issues

install WAN access security measures.

Context of, and specific resources for assessment

Assessment must ensure:

a site where installation and maintenance of a WAN may be conducted

use of tools, equipment and materials currently used in industry

relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

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 installing and maintaining a WAN

direct observation of the candidate troubleshooting WAN communication problems

oral or written questioning to assess required knowledge.

Guidance information for assessment

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

ICTTEN2209A Build and maintain a secure network

ICTTEN4212A Apply advanced routing protocols to network design

ICTTEN4213A Configure and troubleshoot advanced network switching.

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.
