How your INBDE score works

Results for the Integrated National Board Dental Examination (INBDE) say pass or fail. Behind that, the Joint Commission on National Dental Examinations (JCNDE) works out an INBDE score on a scale from 49 to 99, and 75 is the minimum to pass. If you pass, “pass” is all you see. If you fail, your report gives the overall scale score and a breakdown to help you prepare again.

What’s the INBDE passing score?

It’s a scale score of 75, and your overall score alone decides the result, not your subarea scores. The number isn’t a percentage or a raw count of correct answers. The JCNDE is blunt about it: a 74 doesn’t mean one more right answer would have gotten you through.

The exam isn’t graded on a curve. Experts recommend the standard and the JCNDE sets it, so your result doesn’t depend on who tested alongside you. The JCNDE set this standard in 2024, and the failure rates page has the dates. When a standard changes, the JCNDE adjusts the scale so that 75 stays the minimum.

INBDE scoring across different exam forms

Candidates don’t all see the same questions, because many forms of the exam are in use. Each form includes questions that let the JCNDE put scores on one common scale, adjusting for small differences in difficulty. It says a score means the same thing whichever form you got.

Guessing and unscored questions

Answer everything, because you’re not penalized for guessing. The scoring does take account of how difficult each question is, its quality and how easy it is to guess.

Some questions are experimental and don’t count. They’re there to test whether they’re fit for future exams, and they look the same as scored ones, so you can’t pick them out.

What you see if you fail

Your report gives your overall scale score, plus how you did across the three clinical content areas and ten Foundation Knowledge areas. The JCNDE provides this for remediation.

Changes the JCNDE has on its roadmap

Its report on its April 24, 2026 meeting lists plans, not decisions, for the dental exams:

  • A dental practice analysis in 2026 and 2027, to inform future content.
  • Expert panels in 2027 on updating the test specifications.
  • Expert panels in 2028 on recommending new performance standards.
  • Considering multi-stage adaptive testing, as a way to shorten the INBDE and increase test security.
