DISIPC Passing Score 2026: Exactly What You Need to Pass

The Number: 400 on a 100-900 Scale

The Dental Industry Specialist in Infection Prevention and Control (DISIPC) credential is administered by the Dental Assisting National Board (DANB), developed in collaboration with the Association for Dental Safety (ADS), formerly OSAP. The DANB exam outline states a passing scaled score of 400 on a scale that runs from 100 to 900.

That single figure is the answer most candidates are searching for, but it is easy to misread. A scaled score is a reporting convention. It exists so that results mean the same thing regardless of which version of the exam you happened to receive. Your score report translates your performance into this common scale, and 400 is the line between not yet qualified and certified.

If you are still deciding whether to pursue the credential at all, our overview of what DISIPC certification is covers the basics, and the DISIPC requirements guide explains who qualifies to sit for it.

Why 400 Is Not a Percentage

The most common mistake candidates make is converting 400 into a percentage and aiming for a magic count of correct answers. DANB describes the DISIPC standard as criterion-referenced, which means it measures whether you demonstrate the knowledge required of a competent infection prevention specialist, not how you rank against other test takers.

Three practical consequences follow:

• There is no published raw cutoff. You cannot say "I need 70 right out of 100," because the outline does not define the standard that way. Any number you see quoted online as a required percentage should be treated as a guess.
• The scale is not linear in an obvious way. 400 sits well below the midpoint of a 100-900 range, but that does not mean the exam is easy to pass. The scale is a reporting device, not a measure of difficulty.
• Passing is not graded on a curve. Because the standard is fixed to a competency criterion, a strong or weak group of candidates on test day does not move the line.

DANB also allows unscored pretest items on its examinations. The sources reviewed do not publish a reliable breakdown of how many items on a given form are scored versus unscored, so it is not possible to say exactly how many of your 100 questions count toward the 400. The right response is to treat every question seriously and not try to guess which ones "don't count."

What You Face on Exam Day

Understanding the format matters because the passing score is earned under specific conditions. The DISIPC exam is delivered by Pearson VUE, either at a test center or through online proctoring.

The two rules that affect your score directly

First, candidates must answer every question to receive a pass/fail result. An unanswered item is not a harmless skip. Second, DANB's published preparation guidance says that submitted answers cannot be revisited or changed. Together these rules shape your pacing: 75 minutes across 100 questions leaves well under a minute per item on average, and there is no second pass to fix an early mistake.

Practice accordingly. Train yourself to read the stem, eliminate clearly wrong options, commit, and move on. If you are curious how this format feels relative to other credentials, the DISIPC difficulty guide breaks down where candidates tend to struggle.

Where the Points Come From: Three Domains

Your 400 is built from performance across three official examination objectives. The weights below come from the Exam Outline Overview.

The question-count column is a simple proportional illustration of the weights, not an official item count for any individual exam form, and it is complicated by the presence of unscored pretest items.

Because Domains 2 and 3 together account for 85% of the exam, weakness in either one is very hard to offset with strength in Domain 1. For a deeper walk-through of each area, read the complete guide to all three DISIPC content areas.

Results, Timing, and What Happens Next

After you finish, DANB reports that official results are available by email in one to three business days. Plan your own timeline around that window rather than expecting an instant score on the screen.

Scheduling has its own clock. Applications are submitted online only, and once approved, candidates have 60 days to schedule and take the examination. That window is part of how you should think about your readiness: apply when you can realistically be prepared within about two months, not when you are only starting to read. Our DISIPC exam dates and scheduling guide covers the logistics in more detail.

Eligibility Comes Before the Score

You cannot reach the 400 threshold unless you are first approved to test. DANB offers two pathways, and both still require passing the DISIPC exam.

Pathway I

Pathway I requires all three of the following:

1. The Dental Infection Prevention and Control Certificate
2. One additional accepted education option
3. At least 1,040 hours of qualifying work experience

Accepted additional education options include the DALE Foundation DANB ICE Review; From Policy to Practice: ADS's Guide to the CDC Guidelines; ADS's OSHA & CDC Guidelines: ADS Interact Training System; the ADS Dental Infection Control Boot Camp; graduation from a CODA-accredited dental-assisting or dental-laboratory technology program; or an accepted associate-or-higher degree in a dental, healthcare, life-sciences, or applied-life-sciences field.

Qualifying work includes dental office management, dental-industry sales, customer service, service technology, manufacturing or distribution, and dental inspection or investigation. Experience is self-attested and subject to audit, so keep accurate records.

Pathway II

Pathway II requires current CDIPC certification. The DISIPC is a distinct credential from CDIPC, and holding CDIPC makes you eligible to test but does not waive the exam.

The full eligibility picture is laid out in the DISIPC requirements guide.

What Preparation Products Can and Cannot Tell You

Many candidates complete the DALE Foundation Dental Infection Prevention and Control Certificate Program, a separate USD 215 educational product with an estimated 12 course hours and its own assessment. The DANB ICE Review is another separate product at USD 130. Public descriptions of both were reviewed for this article; paid course content was not.

The important point for score expectations: neither course's hours nor its assessment results describe the DISIPC certification exam. Finishing a certificate program, or scoring well on its internal assessment, does not tell you that you will reach a scaled 400 on the real exam. These products also do not establish exhaustive DISIPC coverage or any additional official domains. ICE preparation in particular is supplemental and cannot replace the DISIPC blueprint.

A Domain-Weighted Plan Built Around the Standard

Since the passing standard is competence-based and the weights are known, the most efficient plan allocates time in proportion to domain weight while front-loading the regulatory vocabulary that the other domains assume. Here is one way to sequence a four-week approach.

The final week deserves particular attention. Because you cannot revisit answers and must answer everything, timed full-length practice teaches pacing under the exact constraints you will face. Use the DISIPC practice tests to simulate that environment, and keep our one-page DISIPC cheat sheet handy for last-minute review of high-yield facts.

Reading questions the way the exam writes them

The exam is built around practical decision-making in dental settings. When a stem describes a scenario, ask which domain it is really testing. A question about a contaminated surface may look like Domain 3 environmental cleaning but hinge on a Domain 2 transmission concept. Candidates who understand why a protocol exists answer these confidently; those who memorized steps in isolation often stall. If you want more practice thinking this way, try a few sets in the main practice test site.

After You Pass: Renewal and Careers

Reaching 400 is not the end of the obligation. The DISIPC credential renews annually. For DISIPC alone, renewal requires six infection-control continuing-education credits each year from qualifying ADA CERP or AGD PACE providers, plus a USD 50 annual fee. The DISIPC-only renewal document does not list CPR certification as a requirement, but candidates who also hold other DANB credentials should check their combined requirements rather than assume this applies to every credential they hold.

On the career side, the relevant work experience for eligibility hints at who benefits from this credential: people in dental-industry sales, customer service, service technology, manufacturing, distribution, and dental inspection or investigation roles, along with office managers.
