DANB 2026: Everything You Need to Know About the Dental Assisting National Board
DANB 2026: Everything You Need to Know About the Dental Assisting National Board
For anyone considering a career as a dental assistant, understanding the Dental Assisting National Board, commonly known as DANB, is an important step. DANB develops and administers examinations and professional certifications for dental assistants, while individual states determine which credentials, examinations, education and permits are required to perform specific dental assisting duties.
In 2026, DANB remains particularly important for students entering dental assisting because certifications such as the Certified Dental Assistant (CDA) and National Entry Level Dental Assistant (NELDA) can provide nationally recognized credentials, while DANB examinations are also incorporated into state licensing requirements in places such as New York.
What Is DANB?
The Dental Assisting National Board is a national credentialing organization that develops examinations and certifications for dental assistants. Its examinations cover subjects including infection control, dental radiography, anatomy and chairside assisting.
DANB certification should not be confused with a state dental assisting license. A dental assistant's legal scope of practice depends on the state in which the person works. DANB maintains state-specific information to help candidates determine which examinations and credentials apply to them.
For students, 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.
What Is the DANB CDA?
The Certified Dental Assistant, or CDA, is one of DANB's principal professional certifications.
The CDA examination combines three components:
General Chairside Assisting (GC)
Radiation Health and Safety (RHS)
Infection Control (ICE)
As of 2026, DANB lists the combined CDA examination at 245 questions with a 195-minute testing time and a 60-day testing window.
Who Can Take the CDA Exam?
DANB currently provides several eligibility pathways.
Pathway I is available to graduates of CODA-accredited dental assisting or dental hygiene programs who also maintain current hands-on CPR, BLS or ACLS certification from a DANB-accepted provider.
Pathway II is designed for experienced dental assistants. Candidates need a high school diploma or equivalent, at least 3,500 hours of approved dental assisting work experience and current accepted CPR, BLS or ACLS certification.
Pathway III includes certain candidates who previously held CDA status, are enrolled in or graduated from qualifying CODA-accredited dental degree programs, graduated from qualifying dental programs outside the United States or Canada, or completed certain accepted post-baccalaureate programs.
A Major DANB Change Coming in 2027
One of the most important developments for dental assisting students in 2026 is DANB's announcement of a new CDA eligibility pathway.
On September 23, 2026, DANB announced that it is expanding CDA eligibility to include certain dental assisting programs located within institutions accredited by agencies recognized by the U.S. Department of Education, even when those programs are not CODA-accredited.
Under the announced pathway, qualifying programs will generally need at least 900 instructional hours, including 300 clinical hours. DANB also announced another qualifying structure involving at least 700 instructional hours, including 200 clinical hours, combined with at least 200 additional hours of work experience.
DANB says programs can apply for approval during 2026 and that the new pathway is expected to become officially available in early 2027.
This is significant because students should not automatically assume that a dental assisting program must be CODA-accredited in order for its graduates to eventually pursue CDA certification. The exact status of a program and its eligibility pathway should be confirmed with DANB.
What Is the NELDA?
The National Entry Level Dental Assistant, or NELDA, is another DANB certification designed for people entering the dental assisting profession.
The NELDA examination includes:
Anatomy, Morphology and Physiology (AMP)
Infection Control (ICE)
Radiation Health and Safety (RHS)
DANB currently lists the NELDA examination at 230 questions, with 180 minutes of testing time and a 60-day testing window.
NELDA has several eligibility pathways. These include graduation from qualifying dental assisting programs, certain Job Corps programs, qualifying high-school dental assisting programs and specified amounts of dental assisting work experience.
For someone entering dental assisting without extensive professional experience, NELDA can therefore be an important credential to investigate.
What Is the DANB RHS Exam?
The Radiation Health and Safety examination, or RHS, tests knowledge related to dental radiography and radiation safety.
As of 2026, the RHS examination consists of 75 questions and has a 60-minute testing time. DANB offers the examination through testing centers and online proctoring, and the RHS examination is also available in Spanish.
RHS is also a component of both the CDA and NELDA certification pathways.
What Is the DANB ICE Exam?
The Infection Control examination, known as ICE, evaluates knowledge related to infection prevention and control in dental settings.
ICE is used as a component of several DANB credentials, including the CDA and NELDA. DANB also offers an RHS/ICE combined examination, which consists of 150 questions and has a 120-minute testing time.
What Is the General Chairside Exam?
General Chairside Assisting, or GC, focuses on the knowledge required for chairside dental assisting.
GC is one of the three components of the CDA examination, together with RHS and ICE. Students preparing for the CDA should therefore study all three areas rather than treating the CDA as a single subject examination.
Does Every Dental Assistant Need DANB Certification?
No.
Dental assisting requirements vary by state. Some states recognize or require DANB examinations or certifications for specific duties, while other states have their own education, examination, registration or permit requirements.
This distinction is particularly important for students deciding which dental assisting program to attend. A program that prepares students for employment in one state may not automatically satisfy the requirements of another.
DANB's state requirements database is therefore one of the best places to begin researching requirements before enrolling in a program.
DANB and New York Dental Assistants
New York provides an important example of how DANB and state licensing can work together.
In New York, anyone using the professional title "Registered Dental Assistant" must be licensed by New York State. The New York State Education Department requires applicants to meet education and examination requirements.
New York requires qualifying applicants to pass appropriate DANB examinations. Depending on the candidate's educational and DANB eligibility pathway, this can involve the CDA examination or a combination of the New York Professional Dental Assisting (NYPDA), Radiation Health and Safety and Infection Control examinations.
The NYPDA examination is a New York-specific DANB examination. DANB currently lists it at 95 questions with a 75-minute testing time and a 60-day testing window.
Importantly, passing the required examinations alone does not complete New York's licensing process. The state's education requirements must also be satisfied.
How Should You Prepare for the DANB?
Preparation should begin with the official DANB examination outline for the specific examination you plan to take.
Students should become familiar with the subjects tested, review dental terminology and clinical concepts, and use practice questions to identify areas requiring additional study.
The DALE Foundation, DANB's official educational organization, provides practice tests, review courses and other examination preparation materials.
For students enrolled in a dental assisting program, classroom instruction and hands-on clinical training can provide an important foundation for the examination. Additional DANB-specific preparation can then be used to become familiar with the format and subject areas of the actual examination.
Is DANB Certification Worth It?
The answer depends partly on the state in which you intend to work and the duties you want to perform.
A DANB credential can demonstrate professional knowledge and may satisfy or contribute to state requirements. In some states, particular DANB examinations or certifications are directly incorporated into requirements for registration, licensing or expanded dental assisting functions.
For a student choosing a dental assisting career, the most useful approach is to identify the state in which you expect to work, determine its requirements and then choose an educational and certification pathway that matches those requirements.
DANB Frequently Asked Questions
Is DANB a license?
No. DANB is a national credentialing organization. State governments determine licensing, registration and scope-of-practice requirements.
What does CDA stand for?
CDA stands for Certified Dental Assistant. It is a DANB certification consisting of the General Chairside Assisting, Radiation Health and Safety and Infection Control examination components.
What does NELDA stand for?

For example, the current CDA Pathway II requires a high school diploma or equivalent and 3,500 hours of approved dental assisting work experience.
Does passing DANB make me a dental assistant?
Passing a DANB examination or earning DANB certification does not by itself establish the scope of practice in every state. Candidates should check the requirements of the state where they intend to work.
What should I do if I want to become a dental assistant in New York?
New York candidates should review the New York State Education Department's requirements for Registered Dental Assistants and determine which education and DANB examination pathway applies to them.
The Bottom Line
DANB remains one of the most important credentialing organizations in American dental assisting in 2026. Its CDA, NELDA, RHS, ICE and state-specific examinations provide pathways for dental assistants at different stages of their careers.
For prospective dental assistants, the most important step is to understand the difference between national certification and state authorization. Requirements vary considerably, and choosing the right educational program can affect which examinations and credentials a student can pursue.
The 2026 announcement of a new CDA pathway for qualifying non-CODA dental assisting programs also makes this an especially important year for students and schools to monitor DANB's requirements. The new pathway is expected to become available in early 2027.
