Dental Assistant Exam Prep CDA

CDA exam prep for the DANB Certified Dental Assistant credential — 1,300 questions across all three component exams, RHS, ICE, and GC, each with a written explanation. A cda practice test bank organized the way DANB actually certifies you: one component at a time.

WHAT YOU GET
- 1,300 practice questions across 11 areas, led by GC — Chairside Dentistry (250), RHS — Purpose and Technique (200), ICE — Prevention of Cross-Contamination (136), ICE — Processing Instruments and Devices (104), RHS — Radiation Protection (100), plus 6 more.
- A teaching explanation on every question — why the right answer is right, and why each wrong choice is wrong.
- Full-length mock exams: 75 questions, 60 minutes, 75% to pass — the same bar as the real thing.
- 18 study notes distilling the high-yield points.
- 180 flashcards for the facts you have to recall cold.
- Progress tracked area by area, so you can see what is holding you back.
- Works fully offline. No account, no signup.

THREE SEPARATE EXAMS, THREE SEPARATE TRACKS
The CDA is not one test. It is Radiation Health and Safety, Infection Control, and General Chairside, taken and passed independently, and most apps blend them into a single undifferentiated pile. Here each component is its own track with its own progress and its own mock exam — 400 questions in RHS, 400 in ICE, 500 in GC — so you can sit RHS this month and come back for GC later, and always know which component you are actually ready for.

WHO IT IS FOR
- Dental assistants pursuing the DANB CDA credential through any eligibility pathway.
- Students in a CODA-accredited dental assisting program preparing for certification.
- On-the-job trained assistants certifying under the work-experience pathway.
- Assistants who need only RHS or only ICE for their state's radiography or infection control requirement.
- Anyone retaking a single component and wanting a danb practice test focused on that one.
- Candidates comparing danb cda study options who want explanations on every item.

HOW THE EXAM WORKS
The CDA is earned by passing three component exams — Radiation Health and Safety (RHS), Infection Control (ICE), and General Chairside (GC) — each taken separately at a Pearson VUE center, with a scaled passing score. Some states accept RHS or ICE on their own for radiography or infection control requirements. Eligibility pathways, fees, retake waits, and recertification are set by the Dental Assisting National Board — confirm them before you apply.
