About the exam
Each wastewater operator certification exam is composed of 100 multiple-choice questions covering the Need-to-Know Criteria as itemized on WPI’s Website. The current version of the wastewater treatment and collection exams has 110 questions, but only 100 pre-selected questions will be scored. The additional ten questions are interspersed and being pre-tested for future incorporation. All questions should be answered as if they were being scored, since no one knows which are the “real” questions. For more information on content of exams, see the exam preparation information.
