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 installing and testing a spa and applying theoretical knowledge and advanced fault diagnostic skills to identify and repair routine and complex faults in line with regulatory requirements. This includes faults that may not be covered fully by maintenance manual fault diagnosis guides.

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 spas in line with client and enterprise requirements

service spa systems

troubleshoot routine and complex faults in spa systems

complete installation, service and repair 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 spa:

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.

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 that involve applying logical processes, basic principles, system knowledge and experience in conjunction with information in technical manuals to ensure efficient and accurate troubleshooting of faults

literacy skills to read and interpret technical manuals and specifications related to spas

numeracy skills to perform calculations related to troubleshooting faults in spas

research skills to identify and locate technical information on spas

technology skills to use tools and equipment associated with installing, fault finding, repairing and commissioning spas
