A Guide to the Maryland Certification Process and
Preparing for and Taking the Examinations (PDF)

To ensure protection of public health and the environment, operators and superintendents of water and wastewater treatment plants and associated systems are required under Maryland law to be certified. Maryland’s Board of Waterworks and Waste Systems Operators (often referred to as “the Board of Certification,” “the Board of Waterworks,” or just “the Board,”) sets the standards for the examination, education, and experience for operators and superintendents who work in the State’s treatment plants.

The written examination is often the biggest hurdle operators face in the certification process. Each of the 23 certification classifications has its own process-specific examination, designed to ensure that Maryland's operators are technically-qualified.

While it is natural to be worried about the unknown, being anxious can make you less successful. The opposite is also true. When you know what to expect, you are more likely to be relaxed and to be successful. Knowing what to expect when you take the exam, how to prepare for the exam, and how ultimately to be successful.

Historically the pass rate has been low. Since 1984, when the State started offering the exams, the overall pass rate for all exams taken for all classifications is only 34%! Don’t be discouraged if your score is lower than you’d hoped. Do everything you can to prepare yourself, and if you don’t do as well as you’d hoped, don’t be too hard on yourself. Persistence in studying and in taking the exam will ensure your ultimate success.
