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!

Instructions to Assessors

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:

evaluate the capability and limitations of the various access network technologies for present and future needs

source the equipment that will be used across the spectrum of access network technologies

outline the product offerings allowable across all competing access network technologies.

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 computers

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 evaluating the capability of an access network

review of reports completed by the candidate for differing access network equipment and technologies

oral or written questioning to assess knowledge of equipment, technologies and the various product offerings as used within the access network.

Guidance information for assessment

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

ICTNPL4108A Plan the deployment of access network architectures.

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.

Required Skills and Knowledge

Required skills

analytical skills to outline the product offerings allowable across all competing Access Network technologies

communication skills to liaise with internal and external personnel on technical and non-technical matters

literacy skills to:

interpret technical and non-technical documentation

write summary reports in required formats

numeracy skills to interpret data results and evaluate different types of technical data

planning and organisational skills to plan, prioritise and monitor own work

research skills to:

assess the elements and architectures of the various access network technologies

assess the capability and limitations of the various Access Network technologies (present and future needs)

explain the key technologies that make up the access network

interrogate databases and investigate different audit requirements

source the equipment that will be used across the spectrum of access network technologies

technical skills to select and compare benefits and limitations of access network technologies

Required knowledge

detailed knowledge of:

typical access network technologies

the elements and architecture of the various access networks

typical problems and challenges that describe the capabilities of the various access networks
