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:

design viable GPRS (2.5G) and 3G network solutions to meet particular business needs

research design features of 4G cellular networks.

Context of and specific resources for assessment

Assessment must ensure:

budget for designs for convergent cellular mobile networks

cellular mobile network structures

client requirements

expected traffic volume

information on a range of IT business solutions

technical specifications

vendors and vendor offerings and pricing.

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:

oral or written questioning to assess knowledge of current industry networks and design methodologies

review of report prepared by the candidate outlining evaluation process undertaken, including challenges faced and how these were addressed

direct observation of the candidate undertaking multiple antenna positioning

evaluation of network designed by the candidate in terms of performance and suitability of business needs.

Guidance information for assessment

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

ICTRFN6171A Produce and evaluate architecture designs for WiMAX 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.
