Operator Certification Program

Professional Development Hours

Revised On: Nov. 19, 2023 - 11:30 p.m.

Professional development hours (PDHs) involve participation in an organized educational activity related to engineering, biological or chemical sciences, a closely related technical or scientific discipline, or operations management.

A PDH is equal to one hour of contact time. A total of 30 professional development hours are required for each renewal of your operator certification regardless of the number of certificates that are held by an operator.

Continuing education units (CEU) can also be converted to PDHs. One CEU is equal to 10 PDHs.


PDHs are awarded at all workshops hosted by ADEQ throughout the year. All operators, stakeholders and community members are welcome to attend and participate. 

Recorded ADEQ webinars and workshops videos can be used as PDHs. Powerpoint presentation PDFs can not be used as PDHs | Learn More >
