Certification levels / grades / classes

Exam information

Drinking-water applicants obtain eligibility from NDEP then register for PSI testing; wastewater applicants apply through NWEA and take standardized Grade I–IV examinations.

Renewal cycle

Two years for drinking-water and wastewater certificates. Drinking water expires December 31 of the following year when initially issued, then every two years; wastewater renews every two years and allows a six-month late-renewal window before decertification.

Continuing-education requirements

Drinking water: Grades 1–2 require 7 contact hours per two-year period; Grades 3–4 require 14. Separate treatment and distribution certificates require separate hours. For mandatory wastewater plant-operator certification, NAC 445A.287 and the current NDEP renewal instructions require the two-year renewal application/fee but specify no continuing-education prerequisite; NWEA separately administers voluntary specialty credentials.

Reciprocity / out-of-state operators

Drinking-water reciprocity is case-by-case for active out-of-state credentials and equivalent qualifications. Wastewater holders from other states may apply; NWEA evaluates equivalency and does not grant reciprocity based on a reciprocal certificate.
