Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the following is essential:
works effectively within organisational management systems to develop, implement and evaluate pool water maintenance systems, and makes ongoing improvements in line with regulatory requirements and organisational policies and procedures
proposes recommendations to address inadequacies in pool water quality systems and applies effective contingency management techniques to respond to and correct problems with pool water quality and maintenance procedures
identifies the interrelationship between all aspects of organisational safety systems and effectively implements emergency procedures and evacuation plans in the event of a chemical emergency to maintain the safety of facility, staff and patrons
assesses staff training needs to effectively implement water treatment procedures and develops, implements and evaluates staff training programs to meet organisational and regulatory requirements.
Context of and specific resources for assessment
Assessment must ensure:
development, implementation and evaluation of pool water maintenance procedures consistent with legislative and organisational requirements
access to a fully operational aquatic facility or pool environment
access to plant and equipment of an aquatic facility
access to comprehensive information about pool water quality maintenance to allow the candidate to develop a tailored system
access to legislation and organisational policies and procedures that are relevant to the development of pool water maintenance procedures.
Method of assessment
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
portfolio that documents the development of a pool water maintenance system for an organisation, including policies, procedures and staff needs analysis and training plans
reports prepared by the candidate detailing how the maintenance of pool water quality policies, systems and procedures were established for a given project or work activity
project or work activities conducted in conjunction with an industry operator to allow the candidate to develop systems for a specific workplace
third-party reports from key stakeholders or review of reports of the implementation and review processes
case studies and problem-solving exercises to establish systems, policies and procedures for different workplace sizes and types
written or oral questioning or interview to assess knowledge of the legislative requirements of water quality.
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
