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:

produce design plan and requirements of VoIP network

configure and test for voice gateways

design site numbering plan, dial plans and priorities

use networking and network management tools

configure and test real time protocols, call management protocols and gateway signalling protocol in the network elements

implement voice systems and applications.

Context of and specific resources for assessment

Assessment must ensure access to:

site where network installation may be conducted

hardware and software

organisational guidelines

computers

stand-alone and lightweight WLAN controllers and AP

hardware and software LAN/WLAN voice technologies

appropriate learning and assessment support when required

modified equipment for people with special needs.

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 installing, configuring and testing a new or updated network

evaluation of documentation prepared by the candidate outlining testing procedures, test results, recommendation to network changes and completion records

verbal or written questioning of required knowledge.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate.

Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.

Indigenous people and other people from a non-English speaking background may need additional support.

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.

Required Skills and Knowledge

Required skills

communication skills to liaise with internal and external personnel on technical, operational and business-related matters

literacy skills to:

interpret technical documentation

write reports as required

numeracy skills to:

take test measurements and interpret results

evaluate performance and interoperability of network

planning and organisational skills to:

coordinate the process in liaison with others

plan, prioritise and monitor own work

problem-solving and contingency-management skills to:

adapt configuration procedures to requirements of network

reconfigure depending on differing operational contingencies, risk situations and environments

troubleshoot and debug WLAN issues

research skills to investigate appropriate hardware to meet requirements

technical skills to:

select and configure networking devices and assess and implement security requirements

use networking and network management tools.

Required knowledge

codecs and their protocols for use

configuration, verification and troubleshooting procedures to undertake:

basic router operation and routing
