Colorado Revised Statutes Title 25. Health § 25-9-106.5. Education and experience--substitution allowed

Water and wastewater facility operator applicants must have a high school diploma or have successfully completed the high school equivalency examination, as defined in section 22-33-102(8.5), C.R.S.; except that experience or relevant training may be substituted for the high school diploma or successful completion of the high school equivalency examination. Education, training as established under section 25-9-104(2), and cross-experience may be substituted for experience requirements for certification as a water facility operator, as a water distribution system operator, as a domestic wastewater facility operator, as a wastewater collection system operator, as an industrial wastewater treatment facility operator, or as a multiple facility operator; except that at least fifty percent of any experience requirement must be met by actual on-site operating experience in a water facility or a wastewater facility, as the case may be. For the lowest classification of operator in each category, the board may establish rules allowing complete substitution of education for experience for any applicant who passes the applicable examination. For purposes of this section, “cross-experience” means that experience as a wastewater treatment facility operator may be substituted for experience requirements for certification as a water treatment facility operator and vice versa.
