Independence and accuracy
OperatorCertPrep is independent career and study information. It is not affiliated with, endorsed by, or sponsored by Water Professionals International (formerly the Association of Boards of Certification), any state certifying authority, or any water system. Exam facts reflect the published standardized exam format; states set their own eligibility, grades and renewal rules, so confirm current requirements with your state certifying authority before applying or testing. No exam content is reproduced. Researched from published sources, not professional advice.
We work from published primary sources and say so on the page when a figure could not be verified. Nothing on this site is legal, financial, or professional advice, and nothing here guarantees any exam, certification, licensing or business outcome. Confirm current requirements with the relevant certifying body and your local jurisdiction before acting.
