Certified Dental Assistant (DANB CDA) Prep
Certified Dental Assistant (DANB CDA) Prep: Practice Tests and Quiz Review Checklist
This comprehensive preparation program aligns directly with the Dental Assisting National Board (DANB) Certified Dental Assistant (CDA) examination blueprints across the RHS, ICE, and GC component exams. Learners master infection prevention protocols, diagnostic imaging techniques, chairside four-handed dentistry, and emergency management practices through evidence-based clinical instruction. Designed for career advancement, the curriculum equips prospective dental assistants with the theoretical knowledge and practical competencies necessary to pass all three exam components on the first attempt. Every lesson includes tutor notes, a video, a hands-on lab, exercises and a 12-question quiz you must pass at 80%, followed by a pooled final exam and free and paid practice tests. Erudex is independent and not affiliated with Dental Assisting National Board.
Use this checklist alongside the Certified Dental Assistant (DANB CDA) Prep curriculum. A practice score is a starting point for review, not proof that every topic has been mastered. The course, lesson quizzes and practice papers serve different purposes: learn a concept, check it locally, then check mixed recall.
Key points
- •Compare the outline with your learning or examination requirements.
- •Use the free paper to locate gaps, not to certify readiness.
- •Review guessed answers as carefully as incorrect ones.
- •Return to lesson exercises before attempting broader assessment.
Match the preparation to your syllabus or learning goal
Master infection control, radiation health and safety, and general chairside assisting to achieve DANB CDA credentialing.
Available tracks: Professional Track. Compare the course outline with your teacher's requirements or the current external exam objectives before deciding which topics need additional preparation. Broad preparation does not establish complete coverage of every board, grade or jurisdiction.
- •Execute rigorous infection control and sterilization protocols adhering to CDC, OSHA, and EPA regulatory standards.
- •Produce diagnostic intraoral and extraoral dental radiographs while enforcing ALARA radiation safety principles for patients and operators.
- •Perform four-handed chairside assisting across operative, restorative, and specialty dental procedures.
- •Accurately record patient medical histories, clinical charting, vital signs, and diagnostic assessment data.
- •Identify and respond effectively to medical and dental emergencies utilizing standard life support protocols and emergency pharmacotherapy.

Use the free paper as a short diagnostic
Sign in to take the fixed free practice paper. This course offers 1 free paper, with 10 questions per paper. Record the topic and reason for each mistake; repeating a fixed paper may improve familiarity without demonstrating broader readiness.
Paid practice papers contain 30–50 questions. Purchased papers support saved continuation and review; use the actual explanations to identify what needs more study.
Make a correction log before the final assessment
For each missed or guessed question, record the topic, the choice you made, why it was tempting, the correct reasoning and one new example. Separate knowledge gaps from misreading and timing problems. Revisit the underlying lesson rather than memorising the answer's position.
Check the final-assessment instructions on the course page. Erudex quizzes, practice tests and completion records are separate from external school examinations or professional credentials. Consult the relevant awarding body or teacher for current external requirements.
