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:

  • develop, implement and maintain wireless networks
  • install, configure and test wireless access points
  • test security and network to business specifications
  • develop user training material
  • monitor and resolve wireless network issues.

Context of and specific resources for assessment 

Assessment must ensure access to:

  • network technical requirements
  • network infrastructure, including wireless hardware and software
  • appropriate learning and assessment support when required.

Where applicable, physical resources should include equipment modified 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:

  • verbal or written questioning to assess candidate s knowledge of underpinning knowledge and skills
  • direct observation of candidate performing the tasks required to successfully create a small WLAN
  • documentation produced in a small project environment that reflects understanding of client requirements and the technical skills required for a small WLAN.

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.
