On the NBDHE, you can afford to miss approximately 122-140 questions and still pass. This is because the exam uses a scaled scoring system, requiring a minimum score of 75 to pass. While this might vary slightly due to the difficulty of the questions, aiming to correctly answer at least 60-65% of the 350 questions gives you a good buffer. For strategies to maximize your score and more insights, keep reading.
What is the NBDHE?
The National Board Dental Hygiene Examination (NBDHE) is a crucial assessment for individuals aiming to pursue a career in dental hygiene. This exam is instrumental in determining the qualification and competency of dental hygienists aspiring to obtain their licensure.
The NBDHE is designed by the Joint Commission on National Dental Examinations (JCNDE) and plays an integral role in the licensure process across nearly all states in the U.S. The primary purpose of the NBDHE is to assess your ability to understand and apply the significant information associated with dental hygiene practice.
If you are a dental hygienist student or a professional transitioning from another country, the NBDHE serves as a benchmark ensuring that you have the necessary knowledge and skills to provide high-quality dental care.
Preparing adequately for the NBDHE is essential, as passing this exam indicates that you meet the national standards for dental hygiene practitioners. Therefore, understanding the structure and the scoring system of the NBDHE can significantly enhance your chances of success.
How Is the NBDHE Structured?
The structure of the NBDHE is designed to comprehensively evaluate the breadth and depth of your dental hygiene knowledge and clinical skills.
Exam Components
The NBDHE consists of two major components:
- Discipline-Based Questions: This section includes 200 multiple-choice questions. The questions span across pivotal subjects including biomedical sciences, dental and oral health sciences, and clinical dental hygiene services. These disciplines form the bedrock of foundational knowledge every dental hygienist must possess.
- Case-Based Questions: This section comprises 150 multiple-choice questions that present you with case studies. Each case requires you to apply your knowledge and problem-solving skills to real-life clinical scenarios. This ensures that you are not only versed in theoretical knowledge but can also demonstrate practical clinical judgement.
Duration and Format
You should expect to spend approximately 9 hours completing the entire exam. This includes scheduled breaks. The exam predominantly features multiple-choice questions, ensuring a standardized format that facilitates objective evaluation. The case-based questions are designed to mimic realistic clinical situations, allowing you to showcase your decision-making capabilities.
Understanding the NBDHE layout can help streamline your study efforts, ensuring you are well-prepared for both types of questions. Familiarize yourself with these sections to enhance your confidence and performance on exam day.
What Is the Passing Score for the NBDHE?
A critical aspect of the NBDHE is its scoring system, which determines whether you meet the required competency level to practice as a dental hygienist.
Scaled Scoring System
The NBDHE employs a scaled scoring system. This means your raw score (the actual number of correct answers) is converted into a scaled score that ranges from 49 to 99. This conversion adjusts for any minor variations in difficulty between different versions of the exam.
Minimum Passing Score
To pass the NBDHE, you must achieve a minimum scaled score of 75. It’s important to note that this does not equate to answering 75% of the questions correctly. Due to the scaling process, the raw number of correct answers needed to achieve a passing score can vary slightly depending on the overall difficulty of the questions on your specific version of the exam. However, typically, correctly answering around 60-65% of the questions will result in a passing score.
Understanding this score requirement highlights the importance of comprehensive preparation. Aim to answer as many questions correctly as possible to comfortably surpass the threshold.
How Many Questions Can You Miss on the NBDHE?
Translating Scaled Scores to Raw Scores
A common question arises: “How many questions can I miss on the NBDHE and still pass?” While the exact number can vary due to the scaled scoring system, there are general estimates you can rely upon.
Estimated Number of Missed Questions
Given the requirement for a scaled score of 75, you typically need to correctly answer 60-65% of the 350 questions. This translates to being able to miss approximately 122-140 questions and still achieve a passing score.
Factors Affecting the Number
Several factors influence the exact number of questions you can miss:
- Question Difficulty: Different test versions have questions with varying levels of difficulty. The scaled scoring system adjusts for this, which may alter the exact number of correct answers required.
- Overall Performance Distribution: Your performance relative to other test-takers can also impact the scaled score.
Understanding these factors underlines the importance of aiming well above the minimum threshold. Consistent and thorough preparation will help ensure you excel, regardless of question difficulty variations.
By focusing on comprehensive study and utilizing practice questions, you can mitigate the risk and confidently approach the NBDHE.

Factors Affecting Your NBDHE Score
Several factors can influence how well you perform on the NBDHE exam. Understanding these elements can help you strategize more effectively and achieve a passing score.
Question Difficulty
Variations in the difficulty level of the questions can significantly impact your score. The NBDHE uses a psychometric process called statistical equating to ensure fairness across different test versions.
- Consistent Preparation: Always study each topic thoroughly. This strategy can help you perform well, even if your exam includes more challenging questions.
Section Performance
Your performance on different sections of the exam is another crucial factor. Each section may carry different weights, affecting your overall score.
- Balanced Focus: Pay equal attention to both the discipline-based and case-based sections. This balanced focus ensures comprehensive knowledge and practical application skills.
Statistical Equating
Statistical equating adjusts for variations in difficulty across different test forms. This practice ensures that all candidates are evaluated on a level playing field.
- Adaptability: Understand that statistical equating helps account for more challenging questions. Focus on preparing well in all areas to offset any such variations.
Tips for Maximizing Your NBDHE Score
