Endodontist who passed the INBDE on her first attempt.

Published April 4, 2026·15 min read

If you earned your dental degree outside the United States, the INBDE is the written board exam you need to pass for U.S. dental licensure or admission to an Advanced Standing Program. The registration process involves extra steps that most INBDE guides don't cover in detail, the pass rates are meaningfully different from those of U.S.-trained candidates, and the study timeline is longer.

This guide covers the full process: eligibility, ECE credential evaluation, registration, costs, pass rates, what makes the exam harder for international graduates, and how to build a study plan around it. I wrote it because when I was preparing for the INBDE, most of the guides I found assumed a U.S. dental school background. The advice didn't always apply!

I'm Dr. Silppa. I'm an endodontist who trained in India, specialized in endodontics, practiced for several years, and then moved to the United States. I earned my MPH at the University of New Haven while simultaneously preparing for the INBDE and passed on my first attempt. I now write the practice questions for Blip Dental.

Do international dentists need to take the INBDE?

Yes. The INBDE is required for all international dental graduates (IDGs) pursuing U.S. dental licensure or applying to Advanced Standing Programs at CODA-accredited dental schools.

The INBDE (Integrated National Board Dental Examination) is administered by the JCNDE, an agency of the American Dental Association. It replaced the old NBDE Part I and Part II, which were phased out by the end of 2022. If you haven't already passed the NBDE, the INBDE is the only written board pathway available.

For a full overview of the exam format, scoring, and content areas, see our Complete INBDE Exam Guide.

What are the eligibility requirements for international dental graduates?

International dental graduates must complete a credential evaluation through ECE (Educational Credential Evaluators) before their JCNDE application can be processed.

If you graduated from a dental program that is not accredited by CODA (Commission on Dental Accreditation) or CDAC (Commission on Dental Accreditation of Canada), you're classified as a non-accredited program candidate. That applies to the vast majority of international graduates. The key eligibility requirements:

You need a completed dental degree. You must have graduated from your dental program (BDS, DDS, or equivalent). Current students who haven't graduated may be able to apply with a Certification of Eligibility form signed by your dean or registrar, but check the INBDE Candidate Guide for current requirements.

You need an ECE credential evaluation. This is the step that's unique to international graduates. ECE evaluates your foreign dental credentials and translates them into U.S. equivalency. More on this process below.

You need a DENTPIN. This is your unique dental identification number issued through the ADA. If you've previously taken the DAT or any other ADA-administered exam, you already have one. If not, you can create one at the ADA DENTPIN portal.

How does the ECE credential evaluation work?

ECE (Educational Credential Evaluators) is a nonprofit organization that evaluates foreign academic credentials for U.S. institutions. The JCNDE requires an ECE report before it will process your INBDE application.

Here's the process step by step:

Step 1: Create your DENTPIN first. You'll need it when you submit your ECE application. Use the same name on both your DENTPIN and your ECE application. Mismatches cause delays.

Step 2: Start your ECE application. Go to the JCNDE page on the ECE website and select "start your application." You'll need to create an ECE account and submit documentation specific to your country. Required documents typically include your degree or diploma certificate, transcripts or mark sheets for all examination attempts, and (for some countries) an internship completion certificate.

Step 3: Choose your report type. For the INBDE exam only, a U.S. General Report ($110) is sufficient. If you're also applying to Advanced Standing Programs, most dental schools require a U.S. Course-by-Course Report ($199), and this report is also accepted by the JCNDE. If there's any chance you'll apply to dental schools, order the Course-by-Course. You don't want to pay for two separate evaluations.

Step 4: Request that ECE send your report to the JCNDE. This is part of the application process. ECE will transmit your evaluation directly.

Step 5: Wait for processing. Most ECE orders are completed within about 5 business days after they receive all required documents, but some take longer. If your documents aren't in English, you'll also need certified translations, which adds time. Start this process early.

One thing that sometimes trips people up: the Certification of Eligibility form and the ECE evaluation are different things. The Certification of Eligibility is a form signed by your dental program's dean or registrar, required for students who haven't yet graduated. The ECE evaluation is the credential assessment required for all non-CODA graduates regardless of graduation status.

How do you register for the INBDE as an international graduate?

Once your ECE evaluation is processed and received by the JCNDE, registration follows the same path as any other candidate, with the addition of the non-CODA processing fee.

Step 1: Log in to the JCNDE application portal using your DENTPIN.

Step 2: Submit your application and pay the exam fee ($890) plus the non-CODA processing fee ($435). Both are non-refundable.

Step 3: Wait for your eligibility confirmation email from the JCNDE. This confirms you're cleared to schedule.

Step 4: Schedule your two-day exam window at a Prometric Testing Center. Book 60 to 90 days in advance. Both exam days must occur within 7 days of each other at the same test center.

How much does the INBDE cost for international dentists?

The total cost for an international dental graduate taking the INBDE for the first time is approximately $1,435 to $1,524, depending on the ECE report type.

Here's the full breakdown:

INBDE exam fee: $890 (non-refundable, non-transferable)

Non-CODA processing fee: $435

ECE General Report: $110 (sufficient for the INBDE exam only)

ECE Course-by-Course Report: $199 (required by most Advanced Standing Programs, also accepted by the JCNDE)

Total (exam only path): approximately $1,435

Total (exam + school applications): approximately $1,524

These figures don't include potential Prometric rescheduling fees ($50 or more depending on notice given), additional score report requests, or the $65 results audit fee. If you need to retake the exam, each attempt is another $890 plus another $435 processing fee.

For context, the exam alone costs a U.S. dental student $890. The international pathway adds $545 to $634 in mandatory fees before you answer a single question.

Always verify current fees at the JCNDE website and the ECE website before applying.

A note: this guide covers the INBDE exam process based on publicly available JCNDE and ECE information and my own experience as an international dental graduate. It is not legal, immigration, or licensing advice. If you have questions about visa status, work authorization, or jurisdiction-specific licensure requirements, please consult a qualified professional.

What are the INBDE pass rates for international dental graduates?

In 2024, the first-time failure rate for candidates from non-accredited programs was 25.3%. For retakers, it was 52.8%.

These numbers shifted significantly in 2024 after the JCNDE raised the INBDE's performance standard. Here's the trend for first-time, non-accredited program candidates:

2021: 1,340 candidates, 33.1% failure rate

2022: 2,144 candidates, 25.3% failure rate

2023: 3,277 candidates, 16.0% failure rate

2024: 4,137 candidates, 25.3% failure rate

The improvement from 2021 to 2023 reversed in 2024 when the new standard took effect. For retakers from non-accredited programs, the numbers are tougher: the failure rate jumped from 33.8% in 2023 to 52.8% in 2024. More than half of international retakers failed again under the new standard.

Two things worth noting about these numbers. First, "non-accredited programs" in the JCNDE data includes virtually all international graduates. Second, the 2024 annual figures blend candidates who tested before June (old standard) and after June (new standard). The post-June failure rate is almost certainly higher than the 25.3% annual average.

For the complete data breakdown, including accredited-program rates and the full context on the 2024 standard change, see our full data pass rate breakdown blog post.

Why is the INBDE harder for international dental graduates?

The gap isn't about intelligence or clinical skill. It reflects structural differences between how dental programs outside the U.S. are designed and what the INBDE specifically tests.

The integration format is unfamiliar. Many international programs teach biomedical sciences and clinical dentistry as separate tracks. The INBDE tests them together. A pharmacology question might appear inside a periodontal treatment planning case. A microbiology concept might show up in an oral surgery scenario. If your training compartmentalized these subjects, the integration can feel disorienting.

Patient Box reasoning is a learned skill. The INBDE's Patient Box format presents you with a standardized patient scenario (chief complaint, medical history, medications, clinical findings) and asks you to make clinical decisions. This is distinctly American in its design. If your program emphasized different clinical reasoning frameworks, you need practice adapting to this format specifically.

The clinical emphasis is U.S.-centric. Treatment protocols, standard-of-care guidelines, medication dosing conventions, and even the way questions are phrased reflect U.S. clinical practice. Some of this aligns with what you learned. Some of it doesn't. You need to identify those gaps and fill them deliberately.

English-language testing under time pressure adds cognitive load. Even if your English is strong, processing clinical scenarios in your non-native language at ~90 seconds per question is a different challenge than having unlimited time to read. Speed practice in English is important.

None of these challenges are insurmountable. But they do mean your study approach needs to account for them explicitly, which is something most generic INBDE study guides don't address.

How long should international dentists study for the INBDE?

Most international dental graduates need 3 to 6 months of focused preparation. Some take up to a year depending on their baseline and how recently they completed their training.

That range is wider than the 4 to 12 weeks typical for U.S. dental students, and there's a reason. You're not just reviewing material you learned in a U.S.-aligned curriculum. You're also bridging content gaps, learning a new exam format, and building speed in English-language clinical reasoning.

A few factors that affect your timeline:

How recently you practiced or studied. If you graduated recently and have been actively practicing, your clinical knowledge is fresh and you may be closer to the shorter end. If it's been several years since you were in a classroom or clinic, budget more time for content review.

Your familiarity with U.S. clinical protocols. If you've worked in U.S. clinical settings (even dental hygiene, assisting, or research), you've absorbed some of the clinical context the INBDE assumes. If you haven't, that context needs to come from your study materials.

Your English-language comfort with clinical terminology. This is separate from general English fluency. Medical and dental terminology, patient case descriptions, and the specific phrasing of INBDE questions take practice to read quickly and accurately.

How should international dentists approach INBDE study differently?

The core study phases are the same as for any candidate (content review, active drilling, weak-spot targeting), but the emphasis and pacing shift. Here's what I'd recommend.

Start with the JCNDE INBDE Guide

Download the official INBDE Candidate Guide and the INBDE Test Specifications. Read them before you open any other resource. Understand the Foundation Knowledge weights, the Clinical Content areas, and the exam format. This document shapes your entire study plan.

Build a content foundation with U.S.-aligned resources

Mental Dental (free YouTube videos by Dr. Ryan) is where most people start for content review, and it's solid for high-yield coverage. Cross-reference with your own training to identify gaps. Areas where your program diverged from U.S. standards are your priority review targets, not areas where you're already strong.

For the topics that carry the most weight on the exam, check out our post on high-yield topics!

Shift into high-volume question practice as early as possible

Content review is necessary but passive. The skill that carries you on exam day is the ability to read a clinical scenario, identify what's being asked, and select the right answer in under 90 seconds, hundreds of times in a row. That skill comes from practice volume.

When you start drilling, pay attention to two things: which subjects you're consistently getting wrong (those are your content gaps) and how long each question takes you (that's your pacing gap). Both need to improve over time.

For more on why question volume matters and how to structure your drilling, see How to Actually Study for the INBDE.

Practice the Patient Box format specifically

The Patient Box is the most distinctly INBDE element. Each one presents a patient scenario with more information than you need. Part of the skill is triaging what's relevant and ignoring what isn't. If this format is new to you, practice it deliberately. Don't just answer the question; practice reading the box efficiently.

For a step-by-step framework on approaching case-based questions, we have a post on INBDE caselets.

Build exam-day stamina

The INBDE is 500 questions over two days. Day 1 alone is 360 questions across roughly 8 hours. This is a physical and cognitive endurance test. If you're not doing timed, full-length practice sessions in the weeks before your exam, the fatigue will catch you off guard.

What about Advanced Standing Programs?

Most international dentists taking the INBDE are doing so as part of applying to Advanced Standing Programs (also called International Dentist Programs) at U.S. dental schools. These are typically 2 to 3 year programs that lead to a U.S. DDS or DMD degree.

A passing INBDE score is a prerequisite for most of these programs. Applications typically go through ADEA CAAPID (Centralized Application for Advanced Placement for International Dentists). If you're applying to Advanced Standing Programs, keep these timelines in mind:

CAAPID applications typically open in the spring/summer for the following year's entering class. You want your INBDE result in hand before application deadlines.

Work backward from your target application cycle. If you're aiming to apply in mid-2026, you need to have passed the INBDE by then. Factor in 3 to 6 months of study time, plus the weeks needed for ECE processing and JCNDE approval. Starting 8 to 12 months before your target application deadline is a reasonable planning horizon.

Your ECE report can serve double duty. If you order a Course-by-Course evaluation, it satisfies both the JCNDE requirement and most Advanced Standing Program application requirements. Don't order a General Report if there's any chance you'll be applying to schools.

Frequently asked questions

Can international dentists take the INBDE? Yes. International dental graduates (IDGs) from non-CODA-accredited programs are eligible to take the INBDE. You'll need a DENTPIN, an ECE credential evaluation, and a JCNDE application. Non-CODA candidates pay a $435 processing fee in addition to the $890 exam fee.

How much does the INBDE cost for international dentists? Approximately $1,435 to $1,524 for a first attempt, including the $890 exam fee, $435 non-CODA processing fee, and $110 to $199 for the ECE evaluation. Retakes cost another $890 plus the processing fee.

What is the INBDE pass rate for international dental graduates? In 2024, first-time candidates from non-accredited programs had a 25.3% failure rate (74.7% pass rate). For retakers, the failure rate was 52.8%. These rates increased significantly in 2024 after the JCNDE raised the performance standard.

How long should international dentists study for the INBDE? Most need 3 to 6 months of focused preparation. Some take up to a year. The timeline depends on how recently you trained, your familiarity with U.S. clinical protocols, and your comfort with English-language clinical reasoning under time pressure.

What ECE report do I need for the INBDE? A U.S. General Report ($110) is sufficient for the INBDE exam alone. If you're also applying to Advanced Standing Programs, order a U.S. Course-by-Course Report ($199), as most schools require it and it's also accepted by the JCNDE.

How many times can international dentists retake the INBDE? Up to five attempts total. There's a minimum 90-day waiting period between attempts. After three failed attempts, the waiting period increases to one year.

Is the INBDE harder for international dentists? The exam content is the same for all candidates. What makes it more challenging for international graduates is the integration format (biomedical and clinical sciences tested together), the Patient Box format (distinctly American clinical reasoning style), U.S.-specific treatment protocols, and time pressure in a non-native language. All of these are addressable with the right study approach.

Start practicing

The INBDE is a demanding exam, especially for international graduates. But the data shows that preparation method is the biggest variable. Candidates who do well invest in high-volume question practice, target their weak areas deliberately, and build genuine speed before exam day.
