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:
determine customer requirements
design an internetwork that uses advanced routing and addressing techniques
install an internetwork according to design specification
configure network devices to meet design functionality
document internetwork design, installation and configuration.
Context of, and specific resources for assessment
Assessment must ensure:
a site where design and installation of an internetwork network 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 designing, installing and configuring an internetwork
review of documents prepared by the candidate detailing design and installation
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:
ICTTEN2207A Install and configure a home or small office network
ICTTEN2208A Install and configure a small to medium business network
ICTTEN4210A Implement and troubleshoot enterprise routers and switches.
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.
