The National Swimming Pool Foundation (NSPF) offers a resource of Certified Pool Operator (CPO) classes that are conducted nationwide, including in the Tri-County area. The CPO course is designed to prepare individuals with the knowledge, techniques, and skills of pool and spa operations. This course covers how to effectively and efficiently operate a pool or spa. Anyone operating a public or semi-public swimming pool is required by the Swimming Pools and Mineral Baths regulations to have a valid CPO certificate. However, anyone who owns or maintains a pool, private, public or semi-public is encouraged to take the class.
