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:

source and analyse relevant data to prepare a plan indicating growth potential and recommendations for meeting growth within timeframes

use tools and software packages for forecasting and measurement

identify site or channel capacity, relevant network growth and forecasting growth.

Context of and specific resources for assessment

Assessment must ensure:

access to sites with cellular mobile network

capacity monitoring data and equipment.

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 undertaking a practical monitoring exercise

evaluation of report prepared by the candidate outlining recommendations relating to capacity changes

oral or written questioning to assess required knowledge.

Guidance information for assessment

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

ICTRFN5148A Test and measure cellular phone and network equipment performance

ICTTEN6169A Produce and evaluate architecture designs for convergent cellular mobile networks

ICTPMG8149B Evaluate and use telecommunications management 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.

Required Skills and Knowledge

Required skills

analytic skills to interpret capacity requirements

communication skills to:

liaise with internal and external personnel on technical and operational matters

relate to work associates, supervisors, team members and clients

literacy skills to:

interpret technical documentation, such as equipment manuals, specifications and service orders

write reports using standard formats

numeracy skills to estimate costs and calculate return on investments

planning and organisational skills to plan, prioritise and monitor own work and coordinate the capacity measurement process in liaison with others

problem solving and ability to convey solutions to others

task management skills to work systematically with required attention to detail

technical skills to:

select and use appropriate tests to measure cell capacity usage

use teletraffic statistical data.

Required knowledge

blocking, non-blocking and grade of service

Erlang B measurements

features and operating requirements of test equipment

field measurements for cell traffic capacity

information required to:

analyse and interpret statistical data as applied to teletraffic measurement

prepare and conduct a capacity measurement

legislation, codes of practice and other formal agreements that directly impact on radio communications site transmission

overview knowledge of:

transmission lines

transmitter and receiver architecture and their impact on radio communications traffic

switching architecture and in particular space and time switching

types of adjustments that need to be made to procedures to meet the requirements of particular sites and environmental conditions

typical issues and challenges that occur in telecommunications cellular capacity design and how these may be addressed

workplace and industry environment.
