Certified CPO Pool Service

The Certified Pool/Spa Operator® certification program has delivered more training than any other program in the pool and spa industry since 1972, resulting in more than 375,000 successful CPO® certifications in 93 countries. Many state and local health departments accept the CPO® certification program. A CPO Certified Pool/Spa Operator is a person who has successfully completed a specific course of instruction sanctioned by the Pool & Hot Tub Alliance (PHTA). The PHTA was formed in 2019, combining the Association of Pool & Spa Professionals (APSP) and the National Swimming Pool Foundation (NSPF). With the mission to "Celebrate the Water", PHTA facilitates the expansion of swimming, water safety, and related research and outreach activities, aimed at introducing more people to swimming, making swimming environments safer, and keeping pools open to serve communities.
