Operator Certiciation Program

Operator Certification Program - Certification


There are five levels of operator certification (Grades I – V). To receive a certificate, a person must meet the minimum experience and education requirements and pass a written test. Please refer to the Requirements link for a summary of the experience and education necessary for each grade. Please refer to the Examinations link for further information concerning the final filing and examination dates and exam content. Please direct questions about specific education and experience to the Office of Operator Certification.

Qualifying experience may be acquired in two ways:

  • A person may work either part-time or full-time performing operator duties while holding an Operator-in Training certificate or a wastewater certificate at a lower grade level. Part-time experience will be prorated, e.g. two years of half-time work = one year of qualifying experience.

  • A person may use wastewater experience gained outside California, provided they were a certified wastewater operator and performing duties that would require certification in California.

Please note – Operations duties in an agricultural, industrial or manufacturing facility or on a ship are not considered qualifying experience for purposes of the Operator Certification Program.
