Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 call processing network elements

configure and test voice gateways and LAN switches

evaluate voice call manager server requirements and design voice call systems and applications

implement voice systems and applications on voice call manager

manage security of voice network.

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

oral 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.

Submission Requirements
