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:

conduct a site survey to identify infrastructure features, including:

potential earthing locations

cable routes

locations for cables trays, data cabinets, telecommunication enclosures, and distributors

design infrastructure for access network

design protective earth and functional earth installations

design power infrastructure

design and monitor DC power distribution work.

Context of and specific resources for assessment

Assessment must ensure:

site where installation of supporting infrastructure may be conducted

use of plant, tools and equipment currently used in industry

relevant regulatory and equipment documentation that impacts on work activities.

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 designing metal superstructure to house equipment

direct observation of the candidate designing protective earth and functional earth installations

review of design drawings prepared by the candidate

oral or written questioning to assess knowledge of design issues, types of systems and applications.

Guidance information for assessment

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

ICTNPL4247A Apply compliance requirements to telecommunications work

ICTTEN4241A Design network projects

ICTTEN4242A Conduct site surveys to identify carrier installation requirements

ICTTEN4243A Prepare design drawings and specifications for telecommunications installations

ICTTEN4244A Estimate and quote for carrier telecommunications equipment installations

ICTTEN4246A Design dense wavelength division multiplexing installations.

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.
