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:

use optical power test equipment

measure optical signals at three WDM wavelengths

install splitter in the enclosure

connect input and out optical fibres to the splitter

test optical splitter

complete connection recording

comply with all related OHS requirements and work practices.

Context of, and specific resources for assessment

Assessment must ensure:

a telecommunications operations site where installation of optical fibre splitters in FDH may be conducted

a fibre distribution hub and relevant optical splitter

use of tools, equipment and personal protective equipment currently used in industry

relevant regulatory and equipment documentation that impacts on work activities.

Methods 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 candidate installing optical fibre splitters in FDH

direct observation of candidate applying all related OHS requirements and work practices

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, e.g.

ICTBWN3090B Install lead-in module and cable for fibre to the premises

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.

technical skills to:

clean optical end face

connect optical fibre to feeder port
