Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.

Submission Requirements
