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:

research and evaluate the architectural features and functions of network management systems

research and report

the major features, configuration and functions of management systems

on fault management and accountability procedures

the major features and functions of QoS agreements

on network management techniques

analyse the major features of planning for reliability and survivability.

Context of and specific resources for assessment

Assessment must ensure:

a telecommunications operations site with a network management system

networked computers with relevant software.

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 network management

direct observation of the candidate performing network management functions within a telecommunication system

review of research reports prepared by the candidate.

Guidance information for assessment

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

ICTRFN8180A Analyse a mobile network system

ICTTEN8194A Analyse a telecommunications switching network

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.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Fault identification may include:

congestion

major alarm

minor alarm

out of service

outage

trouble ticket.

Monitoring parameter may include:

grade of service
