What Score is Needed to Pass the NBDHE Exam?

Unlike many exams that report percent-correct, the NBDHE uses a criterion-referenced scaled score ranging from 49 to 99, and you must achieve a minimum scaled score of 75 to pass.

​

Here’s how to interpret your NBDHE scaled score:

• Below 65: Significant gaps in both biomedical science and clinical skills—requires a full review of fundamentals.

• 65–74: Borderline performance—close to passing but focus on weaker domains like research principles or radiography.

• 75–84: Solid pass range—demonstrates competency in core content areas; you’re ready for entry-level practice.

• 85 and above: Exceptional mastery—signals strong readiness for advanced clinical responsibilities and specialty roles.

​

So, what score should you aim for?

While 75 is the official passing standard, target a scaled score of 80 or higher. That safety buffer accounts for form-to-form difficulty shifts and boosts your confidence on test day.

​

Pro Tip:
After each practice exam, review your performance report to pinpoint which of the three content domains - Community Health and Research Principles; Provision of Clinical Dental Hygiene Services; and Scientific Basis for Dental Hygiene Practice- you need to reinforce. Then, devote focused study sessions to those areas to ensure you sail past the 75-point threshold on your first attempt.
