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:

gather data appropriately within information sources and evaluate how the data relates to the access architecture

source major equipment and technologies used in an access network and detail their compatibilities

plan the deployment of an access network architecture, including deployment rules, capacity and capability management and monitoring techniques

complete work within a timeframe typically expected of the discipline, work function and industrial environment.

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 planning the deployment of an access network architecture

review of reports completed by the candidate for differing access network examples

review of final deployment plan prepared by the candidate outlining recommendations for the customer

oral or written questioning to assess knowledge of equipment and technologies 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:

ICTNPL4109A Evaluate the capability of access networks.

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:

interpret data results and evaluate different types of technical data

interpret technical and non-technical documentation and write summary reports in required formats

communications skills to liaise with internal and external personnel on technical and operational matters

planning and organisational skills to prioritise and monitor own work

technical skills to:

identify the various technologies that constitute an access network

interrogate databases and evaluate equipment types and technologies

Required knowledge

Access Network:

architectures and geographical categorisation

information sources

technology and equipment

capacity and capability management

capacity limitation of various platforms

commercial considerations of access network deployment

compatibility issues of technology and equipment
