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 leakdetection activities including conducting basic water loss tests to confirm leaks in swimming pools and spas

operate leakdetection equipment

comply with safety requirements when conducting leakdetection activities

detect leaks and arrange relevant repairs in swimming pools and spas

record and report on leakdetection activities

Context of and specific resources for assessment

Assessment of essential underpinning knowledge may be conducted in an offsite 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 CPP Property Services Training Package

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
