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 testing spa water quality 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

collect samples of spa water for testing

test spa water quality using appropriate equipment

interpret test results and implement treatment processes for identified spa water quality problems

comply with safety requirements when sampling testing and treating spa water

report on outcomes of testing and treating spa water

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

spa water quality parameters

hot water chemistry

spa water contamination

treatment processes for water problems in spas

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
