Evidence Guide

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 sampling and testing water quality in swimming pools and spas and applying appropriate treatment to respond to identified water quality problems.

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

A person should demonstrate the ability to:

  • sample and test or arrange for laboratory testing of water samples from swimming pools and spas
  • identify and implement treatment processes for identified water problems in swimming pools and spas
  • comply with safety requirements when sampling, testing and treating water in swimming pools and spas
  • report on outcomes of testing and treating swimming pool and spa water.

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:
  • water quality parameters
  • water contamination
  • treatment processes for water problems in swimming pools and spas.

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.
