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:

analyse a specialised optical device and prepare a design to integrate it with a network

integrate and test the device

document the integration to the network and recommend enhancements

comply with all related OHS requirements and work practices.

Context of and specific resources for assessment

Assessment must ensure:

sites on which specialised optical device can be integrated

use of test equipment currently used in industry

manufacturer's technical documentation, legislation, codes and standards.

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 performing integration

review of test documentation and reports completed by the candidate

oral or written questioning to assess required knowledge and skill.

Guidance information for assessment

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

ICTOPN5118A Plan and configure dense wavelength division multiplexing systems

ICTOPN5119A Perform acceptance and commissioning test on optical network

ICTOPN5120A Plan for an optical system upgrade and cut over

ICTOPN5122A Test the performance of specialised optical devices.

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.
