Congratulations on your decision to pursue certification in dental assisting! The DANB (Dental Assisting National Board) exams are your next hurdle. Exactly what can you expect with the DANB exams?

What is the Dental Assisting National Board (DANDB)?

The DANB exams are based on content validation, an analysis of the duties commonly performed in actual dental assisting practice. DANB offers five different certifications: NELDA (National Entry Level Dental Assistant, CDA (Certified Dental Assistant), COA (Certified Orthodontic Assistant), CPFDA (Certified Preventive Functions Dental Assistant, and CRFDA (Certified Restorative Functions Dental Assistant).

The DANB component exams are administered on computer at Pearson VUE test centers. All exams are multiple-choice format containing from 80 questions to 210 questions depending on the exam. The time allotted also varies from test to test with a range of 60 minutes to 165 minutes. Specific information on each of exams, including registration information, exam outlines with topics covered, and reference materials can be found at

Most DANB exams use computer adaptive testing (CAT). CAT adapts to the examinee’s ability level and customizes the exam for a more accurate measurement. Each exam begins with a question on par with the passing standard. If it is answered correctly, the difficulty level increases. If answered incorrectly the level of difficulty becomes easier. The final score is based on the difficulty of the questions that were presented and passed.

Official exam results and certificates will be mailed within 2 to 3 weeks after the exam. Candidates can verify DANB credentials using the online Credential Verification tool.
