Credentials
An industry-standard certification issued by the Pool & Hot Tub Alliance (PHTA) for the licensed operation of commercial and semi-public pools. Required by Illinois IDPH for every semi-public aquatic facility.
The CPO credential is the single most common legal requirement for operating a semi-public pool in Illinois. 77 Ill. Adm. Code 820 requires at least one certified operator — CPO or AFO — to be on site during operating hours and the certificate physically posted at the facility. CPO certification is valid for 5 years and covers chemistry, code compliance, equipment operations, and emergency response. Aqua-Guard runs monthly CPO classes at our Schaumburg office from March through June every year.
`CPO` and `AFO` (Aquatic Facility Operator) are different certifications — AFO is administered by NRPA, CPO by PHTA. Both satisfy Illinois requirements.
A pool technician without CPO is not a legal operator — even if they've been servicing pools for 20 years.
The certification is tied to the individual, not the company. If your CPO leaves, the facility technically loses its certified operator until a new one is posted.
