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 carrying out routine maintenance of swimming pool and spa dosing systems.
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 dosing systems
apply safety requirements throughout the work sequence, including using personal protective clothing and equipment
carry out routine maintenance activities on the dosing systems of swimming pools and spas, including identifying 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 dosing 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 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 different types of swimming pool and spa dosing systems and components.
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.
