Evidence Required

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

use data to interpret growth patterns and develop options for core network design which satisfy customer and enterprise financial goals

develop a clearly documented network plan within specification and including merging technological developments and product implementation

Context of and specific resources for assessment

Assessment must ensure

computer assisted design CAD

computer networks

data for network planning

network equipment deployment plans

planning models

standards and regulations

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 core network evaluation and planning

review of reports completed by the candidate for planning the development and growth of the ore network

oral or written questioning to assess knowledge of the various aspects of planning for a core telecommunications network

Guidance information for assessment

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

ICTNPLA Evaluate core network architectures

ICTNPL4112A Evaluate core network architectures

ICTNPLA Plan the deployment of Core Network

ICTNPL4113A Plan the deployment of Core Network

ICTNPLA Develop planning strategies for Access Network design

ICTNPL5096A Develop planning strategies for Access Network design

ICTNPLA Develop planning strategies for building environment design

ICTNPL5154A Develop planning strategies for building environment design.

Aboriginal people and other people from a nonEnglish 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
