Find answers to some of the most common ABC Testing Service questions:
Q: Who do I contact to find out if certification is offered where I live?
A: The certification contacts page has an updated list of contact information for programs. You can search information by state, province or country. If certification is not offered in the state or province where you live, please visit ABC's Certification Program page for information about becoming certified.
Q: How do I know if my program uses ABC exams?
A: You can refer to our Testing Services Client List.
Q: What is the format of ABC examination questions?
A: ABC uses only multiple-choice questions. Most questions have four options (one correct answer and three distractors).
Q: How should I prepare for the exam?
A: ABC’s questions are primarily referenced to the California State University, Sacramento, the Water Environment Federation (WEF), and the American Water Works Association (AWWA) books. A complete reference list is provided in the Need-to-Know Criteria. Candidates are encouraged to visit the Examination Resources section of our website for more information.
Q: How do I prepare to take a computerized exam?
A: A demo of the computerized exam process is available on ABC’s website.
Q: I’d like to check on the status of my score, can I contact ABC?
A: No, ABC is not authorized to release your score; you should contact your test administrator.
Q: My score doesn’t reflect what I think it should. What can I do?
A: If there are any discrepancies with your score, the scanner alerts testing staff to missing, smudged, or inaccurate responses. These are immediately checked by staff.
If you’d like a re-score, you may send a request to ABC Scoring, along with a $15.00 fee and your test will be hand-scored. However, our scoring process is accurate and historically, hand score results have always matched the initial score.
Q: I didn’t pass the exam. How can I better prepare?
A: After taking an exam, you can request a diagnostic report from ABC for $15.00. A diagnostic report shows your strengths and weaknesses in exam areas. Some of our clients already receive diagnostic profiles, which are included within your scoring information. Please check this information before requesting a diagnostic profile.
Q: Will ABC provide exam scores directly to the examinees?
A: ABC only provides test related information to the testing client. The testing client is responsible for providing information to examinees in their state/province.
Q: Does ABC recommend a process for candidates to challenge an examination question?
A: Candidates should provide comments regarding any question(s) they believe contain errors during the examination. Examinees taking a paper-based exam should submit comments on the Question Comment Form; those taking a computerized exam should submit comments electronically during the exam.
ABC will review specific candidate comments relating to the examination at the request of testing service clients. A written response will be provided to the client but not to the candidates. Although ABC will provide a recommendation, the final decision to change the examination score is made by the client.
Q: How does ABC validate the questions and exams?
A: An overview of ABC’s validation process is found in the pamphlet Validating Your Certification Exam.
