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:

plan a frequency allocation for a cellular network

analyse techniques to increase system capacity for a fixed spectrum bandwidth

develop a plan for integration of emerging cellular technologies

analyse the interfaces between a mobile network and customers

research and report the interfacing of major subsystems to other network subsystems

produce an analytical report on cellular mobile convergence with a plan for cellular mobile system integration to existing networks.

Context of and specific resources for assessment

Assessment must ensure:

sites on which cellular network analysis, research and simulation may be conducted

use of test equipment currently used in industry

manufacturer's and enterprise technical documentation.

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:

evaluation of reports prepared by the candidate

review of test documentation and reports completed by the candidate

oral questioning or written questioning to assess required.

Guidance information for assessment

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

ICTPMG8143A Manage a telecommunications project.

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.
