Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

determine the first three layers of the OSI model

evaluate SDH switching and transmission and its ability to create resiliency in the network through various redundant configurations

evaluate the benefits, purpose and structure of ADSL networks and other broadband products

determine and compare data networks with specific reference to IP and MPLS

evaluate the most important routing protocols of internal and external MPLS and the resilience that is built into them

evaluate the limitations of an Ethernet network and how VLAN can be incorporated in them

compare various voice protocols

Context of and specific resources for assessment

Assessment must ensure:

network design documentation and other site related documentation

equipment specifications

live network or training facilities

organisational guidelines

networked telecommunications components.

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 performing an evaluation of core network architectures

review of evaluation report completed by the candidate outlining compatibility and interoperability of competing core network architectures

oral or written questioning to assess knowledge of planning various core networks.

Guidance information for assessment

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

ICTNPL4113A Plan the deployment of core network.

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.
