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

A person should demonstrate the ability to

locate interpret and apply relevant information standards and specifications to carry out routine maintenance of swimming pool and spa heating systems

apply safety requirements throughout the work sequence including using personal protective clothing and equipment

carry out routine maintenance activities on the heating systems of swimming pools and spas includingidentifying faults and undertaking routine repairs in line with manufacturer instructions and client and enterprise requirements

carry out routine maintenance activities on the heating systems of swimming pools and spas, includingidentifying faults and undertaking routine repairs in line with manufacturer instructions and client and enterprise requirements

report complex faults and repair requirements to relevant persons in line with enterprise requirements

restore work area to original condition and check swimming pool or spa heating system and environs for safety hazards

ensure that waste is disposed of and tools and equipment are cleaned and stored in line with WHS and enterprise requirements

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 different types of swimming pool and spa heating systems and components

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
