Description
Employability Skills
Learning Outcomes and Application This unit of competency specifies the outcomes required to prevent, assess and treat water problems in swimming pools and spas. It includes assessing water quality, treating water problems, and completing and documenting water-treatment activities.The unit supports the work of those engaged in maintaining water quality in domestic, commercial and public swimming pools and spas. It applies to swimming pool and spa technicians.No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

The following must be present and available to learners during assessment activities:

equipment:

personal protective equipment (PPE)

swimming pool and spa water testing equipment

materials:

swimming pool and spa chemicals

specifications:

water quality parameters for swimming pools and spas

safety data sheets (SDS) and manufacturer instructions for swimming pool and spa chemicals

physical conditions:

assessment activities are performed in the context of servicing a domestic, commercial or public swimming pool and spa.

Assessment activities are performed on an individual basis under general supervision.

Assessor requirements

As a minimum, assessors must satisfy the assessor requirements in the Standards for Registered Training Organisations (RTOs) current at the time of assessment.
