Everything to Know About the DANB: Dental Assistant Certification, Exams and Requirements

The Dental Assisting National Board (DANB) is one of the most important organizations for dental assistants in the United States. DANB certification can help dental assistants demonstrate their knowledge, qualify for certain state credentials and advance their careers. However, DANB certification is not the same thing as a state license, registration or permit. Requirements vary considerably from state to state.

What Is the DANB?

The Dental Assisting National Board, or DANB, is a national certification organization for dental assistants. Its credentials are recognized or required in many states, and more than 35,000 dental assistants hold DANB's Certified Dental Assistant (CDA) certification.

The DANB administers examinations covering areas such as infection control, radiation health and safety, anatomy and general chairside assisting.

What Is the DANB CDA Certification?

The Certified Dental Assistant (CDA) is DANB's primary professional certification. The CDA consists of three examinations:

Radiation Health and Safety (RHS)
Infection Control (ICE)
General Chairside Assisting (GC)

Candidates can take the three components together through the CDA examination or complete the component exams separately. All three must be passed within five years to earn CDA certification.

The RHS exam covers radiation safety and dental radiography. The ICE exam focuses on infection prevention and control. The GC exam addresses the knowledge required for general chairside dental assisting.

What Is the NELDA Certification?

DANB also offers the National Entry Level Dental Assistant (NELDA) certification. It is designed for individuals beginning their dental assisting careers.

NELDA consists of three examinations: Infection Control (ICE), Radiation Health and Safety (RHS), and Anatomy, Morphology and Physiology (AMP). DANB describes NELDA as a pathway for entry-level dental assistants and a potential step toward CDA certification.

How Difficult Is the DANB Exam?

The difficulty depends on the candidate's education, clinical experience and preparation. The exams test practical dental assisting knowledge rather than simply memorizing terminology.

For example, the current RHS examination contains 75 questions and has a 60-minute testing time. ICE also has 75 questions and a 60-minute testing time, while the GC examination has 95 questions and a 75-minute testing time.

Using the official exam outlines, practicing questions and reviewing dental assisting concepts can help candidates prepare effectively.

DANB Requirements Are Changing

DANB announced a new CDA certification pathway in September 2026. The new pathway is intended to expand access to CDA certification while maintaining the existing examination standard. Under the new pathway, qualifying educational programs will generally need to meet specific instructional and clinical-hour requirements. DANB expects the new pathway to become officially available in early 2027, with programs being approved during the interim period.

Because eligibility rules can change, prospective candidates should always check the current DANB requirements before enrolling in a program or applying for an examination.

DANB Requirements in New York

New York has particularly important DANB requirements for individuals seeking to become Registered Dental Assistants. New York's requirements include education as well as examination requirements.

Depending on the applicant's educational background and DANB eligibility, New York may require the CDA examination consisting of RHS, ICE and GC, or a combination involving the New York Professional Dental Assisting (NYPDA), RHS and ICE examinations.

This is why students in New York should determine their intended credential and eligibility pathway before choosing a dental assisting school.

How Should You Prepare for the DANB?

A strong DANB preparation plan should include:

Completing a comprehensive dental assisting education program.
Reviewing the official DANB examination outline.
Studying infection control, radiation safety, dental anatomy and chairside procedures.
Taking realistic practice questions.
Reviewing areas of weakness before the examination.
Confirming current DANB and state requirements before applying.

For students preparing for the DANB in New York, professional DANB tutoring can also provide additional preparation through structured review, practice questions and individualized instruction.

DANB Certification vs. State Licensing

One of the most important things to understand is that passing a DANB examination does not automatically give someone permission to perform every dental assisting duty in every state. State governments determine licensing, registration, permits and allowable duties.

DANB maintains a state-by-state requirements resource, while New York's Office of the Professions publishes the state's official Registered Dental Assistant requirements.

For anyone considering a career in dental assisting, understanding both the DANB certification process and the laws of the state where they intend to work is essential.
