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:

check and calibrate tools and instruments

perform optical measurements using hand-held instrument

perform RF measurements using hand-held instrument

comply with all related OHS requirements and work practices.

Context of and specific resources for assessment

Assessment must ensure:

sites on which optical and RF measurements installations can be conducted

tools and equipment, currently used in industry, required for measurements.

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 an optical measurement using a hand-held instrument

direct observation of the candidate performing an RF measurement using a hand-held instrument

review of an oral and written report with completed documentation.

Guidance information for assessment

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

ICTBWN3100A Work safely with live fibre to test and commission a fibre to the x installation

ICTBWN3082A Perform tests on optical communication system and components

ICTRFN3055A Install a radio communications antenna and feedline

ICTRFN3175A Operate and maintain radio communications technical instruments and field 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

communication skills to:

liaise with internal and external personnel on technical and operational matters

relate to work associates, supervisors, team members and clients

literacy skills to interpret technical documentation such as manufacturer's instructions

numeracy skills to take and analyse measurements

planning and organisational skills to organise and maintain equipment

safety awareness skills to:

apply precautions and required action to minimise, control or eliminate hazards that may exist during work activities

select and use required personal protective equipment conforming to industry and OHS standards

work systematically with required attention to detail without injury to self or others, or damage to goods or equipment

task management skills to work systematically with required attention to detail and adherence to all safety requirements

technical skills to:

clean an optical connector to an acceptable industry standard

inspect an optical connector for contamination and determine if cleaning is necessary

operate a digital signal level meter (SLM) to measure RF signals on a broadband network or on a satellite or terrestrial television installation

operate a passive optical network (PON) power meter to measure PON signals of various wavelengths on fibre to the home (FTTH) and fibre to the premises (FTTP) network

operate optical loss test set (OLTS) to measure loss of a fibre

Required knowledge

consequences of mating contaminated optical connectors

decibels, dBm and dBmV

optical and RF connector types

RF awareness and RF safety

RF spectrum and optical spectrum limits and allocations

safe handling procedures with optical fibres
