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 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

measurement techniques

swimming pool and spa calculations

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
