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

This unit of competency could be assessed by detecting leaks and arranging relevant repairs in swimming pools and spas.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

A person should demonstrate the ability to:

plan leak-detection activities, including conducting basic water loss tests to confirm leaks in swimming pools and spas

operate leak-detection equipment

comply with safety requirements when conducting leak-detection activities

detect leaks and arrange relevant repairs in swimming pools and spas

record and report on leak-detection activities.

Context of and specific resources for assessment

Assessment of essential underpinning knowledge may be conducted in an off-site context and is to comply with relevant regulatory and Australian Standards’ requirements.

Resource implications for assessment include:

relevant codes, standards and government regulations

a technical reference library with current publications on leakdetection techniques for swimming pools and spas.

Method of assessment

Assessment methods must:

satisfy the endorsed Assessment Guidelines of the CPP07 Property Services Training Package

include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application

reinforce the integration of employability skills with workplace tasks and job roles

confirm that competency is verified and able to be transferred to other circumstances and environments.

This unit could be assessed on its own or in combination with other units relevant to the job function.

Guidance information for assessment

Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.

Assessment processes and techniques should, as far as is practical, take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.

Required Skills and Knowledge

Required skills

communication skills to interact in an ethical manner with clients from diverse social, economic and cultural backgrounds

decision-making and problem-solving skills to identify location of water leaks in swimming pools and spas

literacy skills to read and interpret instruction manuals for leak-detection equipment

numeracy skills to:

perform calculations related to water loss in swimming pools and spas

interpret data output from electronic leak-detection equipment

research skills to identify and locate online calculators for performing calculations related to swimming pool and spa servicing

technology skills to use electronic leak-detection equipment

Required knowledge

common structural leak areas:

cracks

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Basic tests mayinclude:

bucket test

meter test

pump on/pump off test

water loss calculations.

Leak-detection equipment and materials may include:

bucket

communication systems

dye

electronic water loss calculators

hand and power tools

leak-detection equipment:

listening devices

pressure testing

vinyl liner leak detector

personal protective equipment

pipe locating equipment

portable pumps.

Related services may include:

electricity

gas

sewerage

stormwater

water supply.

Leak-detection process mayinclude:

conduct pressure test of plumbing lines
