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 performing measurements and calculations required to complete work tasks associated with servicing swimming pools and spas.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person should demonstrate the ability to:
take measurements of regular and irregular shaped swimming pools and spas
perform area, perimeter and volume calculations of regular and irregular shaped swimming pools and spas that have pool floors with varying slopes and configurations
perform calculations of water loss in swimming pools and spas
calculate quantities of pool chemicals required to improve water quality
calculate flow rates and time taken to fill and empty swimming pools and spas
convert metric units of measurement and convert metric to imperial units of measurement and vice versa
interpret graphical representations of mathematical information related to swimming pools and spas
demonstrate knowledge of:
units of measurement
volume, area and perimeter calculations
weight and mass calculations
measurement techniques.
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:
measurement techniques
swimming pool and spa calculations.
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.
