ExploreAbout this exam
ASSE 6020 is a professional-qualification exam in the ASSE/ASSP 6000 series, the family of personnel certifications administered by the American Society of Safety Professionals (ASSP), the organization formerly known as the American Society of Sanitary Engineering (ASSE). Our catalog publishes the blueprint as six weighted domains: cross-connection control program administration (15 percent), hydraulics and backflow principles (15 percent), backflow prevention assembly types and operation (20 percent), field testing procedures and test equipment (25 percent), troubleshooting, repair and maintenance (15 percent), and codes, standards and regulations (10 percent). The delivery format is multiple choice. The page is written for technicians, inspectors, and program administrators who already work around backflow prevention assemblies and who want a structured, domain-weighted review rather than a first-principles plumbing course. Preparation should mirror the weights: spend roughly a quarter of your study time on field test procedures and gauge work, then assembly operation, then the supporting hydraulics and administrative material, finishing with the codes domain. A sourcing caveat matters here. At retrieval on 2 November 2026, the official ASSE 6020 page redirected to the ASSP home page, so eligibility criteria, fees, sitting length, passing score, retake rules, and validity period could not be confirmed from a primary source; those items are flagged for review rather than guessed, and candidates should verify them directly with ASSP. This platform is an independent study resource and is not affiliated with, endorsed by, or sponsored by ASSP or ASSE.
What you'll study
About ASSE 6020 preparation
What is the format of the ASSE 6020 exam?
Our catalog lists a multiple-choice format only. The item count, whether any practical or hands-on component exists, and the delivery method are not stated in the source we retrieved, so treat them as unconfirmed and check with ASSP before you register.
How difficult is the exam?
Difficulty tracks the blueprint rather than a published pass rate, which we could not verify. Field testing procedures and test equipment carries the largest weight at 25 percent, so candidates who have never run a differential-pressure test on a reduced-pressure assembly typically find that domain the hardest.
How much time do I get, and how long is the sitting?
No time limit or sitting length appears in the source text we retrieved, so we do not publish one. Rather than carry forward a remembered figure that may be out of date, confirm the current appointment length and any break policy directly with ASSP.
What score do I need to pass?
The passing standard is not stated in the material we retrieved, and we do not guess at it. Ask ASSP for the current cut score and scoring method. In the meantime, target comfortable margin on the field testing and assembly operation domains rather than aiming for a bare minimum.
Can I retake the exam, and is there a waiting period?
Retake policy, waiting periods, and any fee for a second attempt are not documented in the source we retrieved. Contact ASSP for the current rules before you plan a retest date, since an assumed waiting period can cost you weeks of preparation time.
What order should I study the domains in?
Follow the weights, highest first. Start with field test procedures and test equipment at 25 percent, then assembly types and operation at 20 percent. Add hydraulics, program administration, and troubleshooting next, and finish with codes and regulations, which is only 10 percent of the blueprint.
What are the most common failure modes?
General patterns rather than published statistics: weak gauge-reading skills, uncertainty about acceptable differential-pressure readings versus the manufacturer's rating, sloppy hose and valve sequencing during a test, and confusion between an assembly failing a test and being installed in a prohibited orientation.
Does the exam test a specific edition of a plumbing or backflow code?
The codes, standards, and regulations domain is 10 percent of the blueprint, but the source we retrieved does not name an edition, a model code, or a jurisdiction. Ask ASSP and your local authority having jurisdiction which codes and editions apply before memorizing specific clauses.
How current is the information on this page?
It reflects a retrieval on 2 November 2026, when the official ASSE 6020 page redirected to the ASSP home page. Because no exam-specific administrative details were available, this page is marked for review and should be treated as a study guide, not an authoritative registration document.
