Evidence Guide

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:

  • adapt technologies to specified technical solutions
  • use site design software and hardware
  • evaluate client specifications against accepted industry practices
  • produce technical designs from business specifications
  • analyse feedback from client and make adjustment to the proposal
  • produce information that can be shared between businesses
  • apply design concepts to business solutions
  • produce technical reports
  • make recommendations and offer optimum design solutions.

Context of and specific resources for assessment 

Assessment must ensure:

  • sites providing:
  • client functional requirements
  • business specifications
  • database software
  • simulation software
  • organisational guidelines
  • network or computer layout
  • site design software and hardware
  • information on a range of ICT business solutions.

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:

  • review of evaluation report prepared by the candidate on predicted performance and costs of the network architecture design outlining the business specifications and recommendations
  • oral or written questioning on required knowledge and skills
  • evaluation of research methodologies and the final proposal prepared by the candidate outlining solutions and recommendations.

Guidance information for assessment 

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

  • ICTOPN6128A Design a dense wavelength division multiplexing systems
  • ICTRFN6171A Produce and evaluate architecture designs for WiMAX networks
  • ICTTEN6169A Produce and evaluate architecture designs for convergent cellular mobile 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.
