Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Risks may include:
microbiological:
amoebae
legionella species
mycobacterium avium and similar mycobacteria
pseudomonas aeruginosa
non-microbiological:
chemical
confined spaces
electrical
entrapment
manual handling
slips and trips
thermal.
Routine spa water tests include:
concentration of disinfectant in use
determining and correcting pH level
microbiological monitoring
determining and correcting total alkalinity.
Spa water microbiological testing may include:
coliform count
cryptosporidium
legionella
pseudomonas aeruginosa
standard plate count
staphylococcus.
Spa water quality includes:
clarity levels
microbiological count
pH.
Spa water treatment procedures may include:
changing spa water
determining and correcting pH level
sanitising the spa
shock dosing
determining and correcting total alkalinity
using chemical dosing equipment.

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 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:
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 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.
