Before You Begin
The ABPA handbook (Sept. 1, 2023) lists the written exam as 100 closed-book questions in 3 hours, with 70% needed to pass. This unofficial mock matches that length, time and pass mark. It draws on the EPA Cross-Connection Control Manual only, not the ABPA bank or your local ordinance, and it does not replace the hands-on performance exam. Source: ABPA Backflow Tester Certification Handbook.
- The timer starts when you begin and the exam submits itself when time runs out.
- Move freely with Previous, Next or the numbered navigator, and flag any question to come back to.
- No feedback is shown until you submit. Unanswered questions count as wrong.
- Nothing is sent anywhere; the exam runs entirely in your browser.

What the Backflow Tester Mock Exam Covers
Each attempt draws 100 questions at random from a pool of 159. The pool covers these topics. Your score report breaks your result down the same way, so you can see which areas need more study.
| Topic | Questions in Pool | Share |
|---|---|---|
| Cross-Connections and Case Histories | 30 | 19% |
| Hydraulics and Backflow Theory | 23 | 14% |
| Devices and Assemblies | 47 | 30% |
| Field Testing and Surveys | 33 | 21% |
| Programs, Ordinances and Definitions | 26 | 16% |
About 53% of the pool is recall and core-concept questions. The other 47% are harder applied questions, such as scenarios, calculations or details that are easy to confuse.
Backflow Tester Mock Exam Pacing Plan
You have 180 minutes for 100 questions, which is about 1.8 minutes per question. Use these checkpoints to stay on pace:
| Checkpoint | Be at or past question | Elapsed time |
|---|---|---|
| First quarter | 25 | 45 min |
| Halfway | 50 | 90 min |
| Three quarters | 75 | 135 min |
If you are behind, flag any question that is taking too long and move on. Leave a few minutes at the end to go back to your flagged questions. Unanswered questions count as wrong, so give an answer to every question before time runs out.
What Score Do You Need?
To pass, you need 70 of 100 correct (70%), so you can miss up to 30 questions. This pass mark comes from the official source cited above. We suggest scoring 10 points above the pass mark on two attempts in a row before you book the real exam, because the pool here is smaller than the official bank.

- Read the source. Each answer cites a section or quotes its source text. Read the surrounding passage, not just the answer line.
- Drill, then retest. Use the adaptive practice test on your weak topics. It gives you more of the kinds of questions you miss. Then take this mock again for a new random set.
- Return to the guide. The Backflow Tester guide covers exam fees, scheduling, retake rules and what to bring on test day.
