AWWA Exam Prep users can conveniently study using the app, which includes sample questions aligned with the latest Need-to-Know Criteria of the Association of Boards of Certification. “The consistent practice of using these prep questions not only appropriately prepares an operator to be successful in passing their exam, they can also enhance their awareness of how to efficiently manage their wastewater collection systems,” said Ken Morgan, P.E., one author of the app questions. “The Exam App was designed to help operator trainees and operators to prepare for their next level certification exam,” said David L. Russell, P.E., another author of the app questions. “The questions were prepared after examination of many state operator’s licensing exam questions for all levels of operators and they reflect the broad range of subject materials which the operator will need to understand in order to operate and manage a modern wastewater treatment plant.
