Who Should Become a CPO?

Anyone who is responsible for managing, supervising, and/or servicing a public or private aquatic facility (such as backyard pools, public pools, homeowner’s association pools, hotel pools, YMCA pools, school pools, and more) should seek Certified Pool/Spa Operator certification.


The Los Angeles Department of Public Health requires that “Any person engaged in … cleaning, servicing or maintaining … public and private pools …” must be certified. The CPO Certification course is a prerequisite for this certification. Click here to learn more about the L.A. Department of Public Health’s swimming pool technician program.
