Association of Boards of Certification Very Small System Practice Exam

The ABC offers practice exams for individuals who want to work in the field of drinking water operations and need to get certified as an operator.

The Association of Boards of Certification (ABC)* is pleased to offer a web-based Very Small Water System Practice Exam. The 50 sample questions match the content and difficulty of the ABC Very Small Water System Certification Examination. Developed using the same procedures as actual ABC examinations, the sample questions may be used as a practice examination to help operators become familiar with the types of questions on the ABC Very Small Water System Certification Exam. The practice exam is not intended to be a substitute for studying for the certification exam.

The practice exam provides many advantages to operators that will be taking the ABC Very Small Water System Certification Exam, such as:

  • An opportunity to prepare for the certification exam. The practice exam is based on the same Need-to-Know Criteria as the ABC Very Small Water System Certification Exam. Questions on the practice exam are similar to questions (but not the same questions) that will appear on the certification exam.
  • An opportunity to become familiar with the web-based testing process. The questions on the practice exam are presented in the same computer format as the web-based very small water system certification exam. This is very valuable in alleviating fears created by not knowing what to expect.
