Frequently Asked Questions

How do I purchase question sets?

You may purchase question sets on the web app or through in-app purchasing on the iOS or Android AWWA Opcert Exam Prep.

How do I know which set will help me prepare for my state’s exam?

Certification requirements vary by state or provincial. Many states follow guidelines from the Association of Boards of Certification (ABC) in their operator exams. Questions marked "Introductory" are designed to aid operators in studying for ABC grades 1 and 2 exams; questions marked "Advanced" are geared toward ABC grades 3 and 4 exams. The Math Refresher question set provides practice in operator math which can apply across all grades. For more information, visit the website of your local water operator certification authority.

What’s the difference between the Opcert Exam Prep app and the book?

The question sets available for Water Treatment and Water Distribution contain over 2200 questions; in the Water Operator Certification Exam Prep book, a subset of 1400 of these questions are included.
