Assessment tool

Version 1.0
Issue Date: May 2024


Field officers, technicians or technical supervisors from service providers, asset owners and contractors who upgrade or reconfigure new and existing equipment apply the skills and knowledge in this unit.

This unit applies to specialist staff with high level technical skills and appropriate authority to coordinate the activities of maintenance personnel. It addresses compliance issues associated with service level agreements.

This unit describes the performance outcomes, skills and knowledge required to effectively upgrade network equipment, increase network capacity, install new network elements and change existing network elements with minimal impact to the customer. It involves the control of planned routine maintenance activities on the network.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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:

evaluate planned network changes, including impact on customer

develop network engineering strategies to manage outages

implement network changes

conduct integration testing, analyse results and rectify faults

enable full functionality of network changes.

Context of and specific resources for assessment

Assessment must ensure:

sites where network changes may be conducted

use of testing equipment currently used in industry

systems manuals, specifications and enterprise policy.

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 implementing network changes

review of network changes plan prepared by the candidate outlining network engineering strategies to manage outages

review of test results and documentation completed by the candidate

oral or written questioning to assess required knowledge.

Guidance information for assessment

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

ICTTEN6044A Coordinate fault rectification and restoration of service following network outages.

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.
