What is the NBDHE?
The National Board Dental Hygiene Examination (NBDHE) is a critical licensure examination for aspiring dental hygienists in the United States. Administered by the Joint Commission on National Dental Examinations (JCNDE), it is designed to assess your knowledge and skills in dental hygiene and related biomedical sciences. Passing the NBDHE is a key step required to practice as a dental hygienist.
The NBDHE measures your readiness and competency to provide oral healthcare services. It ensures that you possess the theoretical knowledge and practical skills needed to deliver quality patient care. By evaluating a broad range of topics, the exam helps maintain high standards in the dental hygiene profession.
Who Needs to Take the NBDHE?
If you are a dental hygiene student or graduate aiming to become a licensed dental hygienist in the U.S., you need to take the NBDHE. This examination is a mandatory requirement for obtaining licensure in all states.

Scoring and Passing Criteria
Understanding the scoring and passing criteria of the NBDHE is crucial for your preparation. Let’s break down how the exam is scored and what you need to achieve to pass.
How is the NBDHE Scored?
The NBDHE uses a complex scoring system that aims to fairly evaluate your knowledge and skills. Here’s how it works:
- Scaled Scores: The raw score (number of correct answers) is converted into a scaled score. This scaling process adjusts for any differences in difficulty across different exam versions, ensuring fairness.
- Passing Score: The minimum passing score is 75. If you achieve this score, you pass. Scores are reported to candidates as “Pass” or “Fail”, rather than providing a numerical score.
What are the Implications of Your Score?
Your NBDHE score has significant implications for your career in dental hygiene:
- Licensure: Achieving a passing score is essential for obtaining your dental hygiene license. Without a passing score, you cannot practice legally.
- Career Opportunities: A pass indicates that you meet the national standards for dental hygiene practice, which can enhance your job prospects and career advancement.
What Happens if You Don’t Pass?
If you don’t achieve a passing score on the NBDHE, don’t worry. You have options:
- Retaking the Exam: You can retake the NBDHE, but you must wait for 90 days before attempting it again. The number of retakes may be limited, so check the specific policies of your state.
- Preparation: Use your additional preparation time wisely. Focus on areas where your performance was weak, and consider utilizing different study resources and practice exams.
