About this exam

The DANB Infection Control Examination (ICE) is a multiple-choice exam from the Dental Assisting National Board that tests whether a dental team member can apply infection prevention principles in a working operatory rather than simply recite them. It is intended for dental assistants and other oral healthcare workers who need to document infection control competency - for a credential, for a state requirement, or for employer documentation. DANB sets eligibility rules and determines how a passing score is used, so candidates should confirm their own situation with DANB before registering.

The content is organized into four areas: infection control concepts and standard precautions; environmental asepsis and surface management; sterilization and disinfection of instruments and equipment; and occupational safety plus the administrative side of an infection control program. Questions tend to be applied, so expect scenarios involving contaminated surfaces, instrument processing sequence, PPE selection, and staff training or exposure records.

To prepare, work from DANB's own published materials, then study area by area using the outline above. Practice explaining why each step exists, not just the order of steps, and rehearse with timed sets.

What you'll study

Common questions

About DANB ICE preparation

What is the DANB ICE, and who should take it?

It is DANB's multiple-choice infection control exam. It suits dental assistants and other oral healthcare team members who need to demonstrate infection prevention competency - for a credential, a state requirement, or employer documentation. DANB sets eligibility rules and decides how a passing score is used, so confirm your situation with DANB before registering.

How is the exam delivered?

DANB's website lists both online proctored exams and test center exams, and it also lists exams offered in Spanish. Availability depends on your location and on which exam you are taking. Check DANB's exam pages for the delivery options currently open to you before you schedule.

How many questions are on the ICE, and how long do I have?

DANB publishes the current item count and time limit in its candidate materials. Those figures are revised periodically, so take them from DANB's own handbook rather than from third-party summaries. Confirm the format on the day you schedule, and rehearse pacing with a timed practice set that matches the published length.

What score do I need to pass?

Passing standards are set by DANB and reported on your score report rather than as a simple percentage of correct answers, because scaled scores and cut scores are updated over time. Verify the current standard in DANB's candidate handbook, and aim well above the minimum by building accuracy across every content area.

Can I retake the exam if I don't pass?

Retake rules - waiting periods, attempt limits, and fees - are set by DANB and can change. Read the retake section of DANB's current handbook or contact DANB before assuming a timeline. Many candidates who fail do so narrowly, so use the domain breakdown on your score report to target your weakest area before rebooking.

In what order should I study the four content areas?

Start with concepts and standard precautions, because every other area depends on understanding how transmission is interrupted. Move next to surface management and instrument processing, which share the same logic of cleaning before disinfection or sterilization. Finish with occupational safety and program administration, the area candidates most often neglect.

What are the most common ways candidates lose points?

Three patterns: memorizing product labels instead of the classification logic behind disinfection levels; confusing order of operations, such as skipping cleaning before sterilization; and skipping the administrative material, including written exposure control plans, training records, and post-exposure follow-up. Scenario questions reward the reasoning, not the vocabulary.

Is this page an official DANB product?

No. This is independent study material and is not affiliated with, endorsed by, or sponsored by the Dental Assisting National Board or the DALE Foundation, which DANB describes as its official affiliate. Use it alongside DANB's published materials, and treat DANB's handbook as the authority whenever anything here appears to conflict.

How do I reach DANB with a question?

DANB is at 444 N. Michigan Ave., Suite 900, Chicago, IL 60611, and its representatives are available M-F, 8:00 a.m. to 4:30 p.m. CT. DANB lists 800-367-3262 as its phone number and also offers email and a contact form on its site. Eligibility, fee, and scheduling questions are best answered there.

How long is a passing score valid?

Validity and recertification periods are set by DANB and tied to the specific credential you are pursuing, so they are not stated here. Check your score report and DANB's renewal pages for the period that applies to you, and note any continuing education requirement attached to maintaining the credential.
