Exams do not need to be taken in the sequential order (passing lower levels and working one's way up); instead, they can be taken in a direct process (take one exam at the desired level of licensure).

Important: Passing the exam does not automatically result in licensure. After successfully taking the exam, candidate Water Operators must apply for their licenses through the Drinking Water Program. (See the 'Licensure' section below.)
