Overview of assessment 

This unit of competency could be assessed by installing and testing a swimming pool or spa dosing system and applying theoretical knowledge and advanced fault diagnostic skills to identify and repair faults in line with regulatory requirements. This includes faults that are not covered fully by maintenance manual fault diagnosis guides. Note: This unit of competency does not include the installation of gas systems.

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

A person should demonstrate the ability to:

• interpret work instructions
• select and use appropriate personal protective equipment
• install and test swimming pool or spa dosing systems, excluding gas systems, in line with client and enterprise requirements
• service swimming pool or spa dosing systems
• troubleshoot routine and complex faults in swimming pool or spa dosing systems
• complete installation, repair and service 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 swimming pool and spa dosing systems:

• operating principles
• components
• faults and troubleshooting.

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.
