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:

design a DWDM installation and associated cabling according to installation brief and installation site conditions

design DWDM system power and ground connections

complete and confirm installation design report.

Context of and specific resources for assessment

Assessment must ensure:

suitable site for DWDM equipment installation

access to tools and equipment required for installation

a range of optical fibres to suit the installation.

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 preparing designs for DWDM systems

review of DWDM designs prepared by the candidate

oral or written questioning of the candidate to assess knowledge of DWDM design practices.

Guidance information for assessment

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

ICTBWN3088B Install optical fibre splitters in fibre distribution hubs

ICTTEN3056A Install telecommunications network equipment.

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

prepare and connect power and ground wires

use a digital multimeter to measure DC and AC voltage and to check continuity.

Required knowledge

DWDM principles of operation

electrostatic discharge: implications and precautions
