Maryland CPO Certification Overview
The CPO Certification in Maryland is widely accepted for meeting the operator training requirements established under state law for public and semipublic aquatic facilities. Maryland regulates pools and spas through the Code of Maryland Regulations (COMAR) 10.17.01, which outlines operator responsibilities, water quality standards, safety protocols, and compliance expectations. This training is one of the most widely accepted pathways for meeting Maryland’s Pool Operator Certification requirements under COMAR 10.17.01. Maryland uses approved CPO courses to qualify operators for the Pool and Spa Operator Certification Card required statewide.
The Training Center’s CPO Certification Course is accepted by Maryland health departments as an approved program for earning the Maryland Pool and Spa Operator Certification Card. The course provides essential training in water chemistry, disinfection, filtration, and public-health compliance required for safe pool operation.
Whether you manage a facility in Baltimore, Montgomery County, Prince George’s County, Anne Arundel County, or Howard County, earning your CPO credential ensures you meet Maryland’s mandates for qualified pool operation.
