2026 INBDE guide

How to Pass the INBDE in 2026

The application sequence, the 2026 fees, how scoring really works, Prometric logistics, and the retake rules — with separate fast paths for internationally trained dentists, U.S. dental students, and repeat candidates. The material rules on this page trace to the primary sources listed below or linked inline — JCNDE's own 2026 Candidate Guide, Technical Report, and Annual Report first — not forum lore.

500 questions over two days
Day 2 must happen within 7 days of Day 1, at the same test center — or you retest at your own expense.
Cost per attempt
$890 + $435 non-CODA fee ≈ $1,325
The $890 exam fee applies to everyone; candidates from non-CODA programs add a $435 processing fee (2026).
Passing standard
Scaled score of 75
On a 49–99 scale. A scale score is not a percentage — 75 does not mean 75% correct.

Most results post within 3 weeks. Passers see "Pass" only — no number.
Retake rules
60-day wait, 4 per 12 months
Pass within 5 years of your first attempt or 5 attempts, whichever comes first; after that, once every 6 months.
2024 change

Choose your path: three kinds of INBDE candidates, three different plans

The INBDE is one exam, but the road to it is not one road. Find your row, read the four lines, and use the jump links — the rest of the guide covers every step in order, and the INBDE prep hub collects every companion surface this guide hands off to.

Internationally trained dentist (non-CODA program) — the default reader of this guide.

  1. Your degree must be confirmed through ECE before you can apply — it is the only evaluator JCNDE names (eligibility).
  2. Budget about $1,325 per attempt: the $890 exam fee plus the $435 non-CODA processing fee (costs).
  3. Testing happens only at Prometric centers in the US and Canada — build travel and visa time into your plan (booking).
  4. In 2025, 34.9% of first attempts in JCNDE's non-accredited cohort failed — plan a real runway, not a cram (the data, study runway).

U.S. or Canadian dental student (D3/D4, CODA or CDAC program).

  1. Your dean's office certifies your eligibility — no credential evaluation needed (eligibility).
  2. Your fee is $890; there is no non-CODA surcharge (costs).
  3. The exam got measurably harder in June 2024 — first-time failure in the CODA cohort went from 0.4% to 7.2% — so calibrate against current data, not an older classmate's experience (the data).
  4. Know the blueprint weighting and the two-day shape before you pick a test window.

Repeat candidate (any background).

  1. You must wait at least 60 days after an unsuccessful attempt, and every retake repeats the full application and fees (retake playbook).
  2. Your failing score report includes a breakdown across 3 clinical content areas and 10 Foundation Knowledge areas — it is your single best planning document (scoring).
  3. Retake failure rates are high — 27.0% (CODA cohort) and 50.5% (non-accredited cohort) in 2025 — which is a strong reason to change your preparation before re-registering (retake playbook).
  4. Track the 4-attempts-per-12-months cap and the 5-year/5-attempt rule before you book anything (retake playbook).

The exam

What the INBDE is — and why Part 1/Part 2 advice is obsolete

The Integrated National Board Dental Examination (INBDE) is the single written board exam for U.S. dentist licensure. It is run by the Joint Commission on National Dental Examinations (JCNDE) — an agency of the American Dental Association — and delivered by Prometric test centers in the United States and Canada. Every U.S. licensing jurisdiction recognizes it: all 50 states plus DC, Puerto Rico, Guam, and the U.S. Virgin Islands. Passing it does not license you by itself — each jurisdiction sets its remaining pathway and licensure requirements.

The INBDE launched on August 1, 2020 and replaced the old two-part National Board Dental Examination: NBDE Part I was discontinued in 2020 and Part II in 2022. That matters for one practical reason: an enormous amount of advice, study material, and forum wisdom still floating around is written for Part 1 and Part 2 — separate basic-science and clinical exams with numeric scores. All of it is obsolete. The INBDE is one integrated, pass/fail exam that mixes foundation knowledge and clinical content in the same questions. If a resource talks about "Part 1," it predates the exam you are taking — our NBDE-vs-INBDE guide covers the transition in full, including how dentists who passed the old NBDE request their legacy score reports today.

One legal detail candidates skim past: agreeing to binding arbitration of disputes is a prerequisite to taking the exam. You accept it as part of applying — read the Candidate Guide's terms so nothing in the fine print surprises you later. The guide itself is a 42-page document with several rule sections worth reading closely; our annotated walkthrough of the 2026 Candidate Guide covers it section by section, including what changed from the previous edition.

Format

The shape of the exam: two days, 500 questions

The INBDE is 500 multiple-choice questions over two days, with a total administration time of 12 hours 30 minutes including the optional tutorial, scheduled breaks, and an optional post-exam survey. Here is the exact structure from the 2026 Candidate Guide:

DaySectionItemsTime
Day 1 (8h 15m)Section 1 — standalone questions100105 min
Section 2 — standalone questions100105 min
Section 3 — standalone questions100105 min
Section 4 — case-based questions60105 min
Scheduled breaks15 / 30 / 15 min
Day 2 (4h 15m)Section 5 — case-based questions70105 min
Section 6 — case-based questions70105 min
Scheduled break (+ optional 15-min survey)15 min

Read the table as two very different days. Day 1 is a volume day: 360 items across 8 hours 15 minutes — three 100-item standalone sections back to back, then a 60-item case section to finish. Day 2 is a case day: 140 case-based items in 4 hours 15 minutes, split into two 70-item sections with a single 15-minute break between them. Across the whole form the split is 60% standalone, 40% case-based — 300 standalone items against 200 case items (60 on Day 1, all 140 of Day 2). A case is a set of two to five items built on one shared stimulus — a Patient Box alone, or a comprehensive stimulus that adds dental charting, radiographs, and photographs. Each day opens with an optional 15-minute tutorial, and every scheduled break is optional too — the schedule above is the ceiling, not a mandate.

The 7-day rule: Day 2 must occur within 7 days of Day 1, at the same test center — the days do not need to be consecutive, but both conditions are hard requirements. Miss either and you are retesting at your own expense. Book both days as a pair before you commit to anything else on your calendar. Day 2 itself — 140 case questions built on the Patient Box — is a distinct format problem with its own pacing math and endurance profile, broken down in our INBDE Day 2 guide.

Format mechanics worth knowing in advance, because they cost points when discovered live:

  • Every item is multiple choice with 3–5 options and one best answer. Formats include completion items, direct questions, and negatively worded stems — the words EXCEPT, LEAST, and NOT are capitalized when they appear.
  • The Patient Box frames case-based questions (and appears with some standalone items too): it presents the information available at the time of the visit, in four labeled sections — Patient, Chief Complaint, Background and/or Patient History, and Current Findings. The rule that trips people: if a field is blank, treat that information as unknown or not available — for example, no allergies listed means none are known. You are expected to consider everything the box shows.
  • Some questions are unscored. Experimental items are mixed in and are indistinguishable from scored ones. Answer everything at full effort. (JCNDE does not publish how many items on a form are scored versus experimental — treat any exact split you see elsewhere as invented.)
  • The timer pauses while items load. Loading lag does not count against your section time, so do not panic-click through a slow screen.

Blueprint

The blueprint that decides your study weighting

The INBDE's published test specifications — JCNDE calls the full structure the Domain of Dentistry — cross 56 Clinical Content (CC) areas with 10 Foundation Knowledge (FK) areas. Every question lives at an intersection of the two. The full lists are on pages 5–10 of the 2026 Candidate Guide; Dentovio reproduces every area title verbatim, with the one-decimal specification matrix, on the full blueprint reference. The weightings below are the rounded 2026 figures.

The 56 CC areas roll up into three clinical content components, and the component level is where JCNDE publishes weights:

ComponentWeight
Diagnosis & Treatment Planning36%
Oral Health Management42%
Practice & Profession22%

By Foundation Knowledge area:

FK areaWeightFK areaWeight
FK112%FK612%
FK27%FK711%
FK38%FK811%
FK411%FK911%
FK59%FK1010%

The ten FK areas carry long official names; grouped by what they cover, JCNDE's own labels run: molecular, biochemical, cellular, and systems-level development, structure, and function (FK1); physics and chemistry applied to normal biology and pathobiology (FK2) and to the characteristics and use of technologies and materials (FK3); principles of genetic, congenital, and developmental diseases and conditions for understanding patient risk (FK4); host defense mechanisms (FK5); general and disease-specific pathology for assessing patient risk (FK6); the biology of microorganisms (FK7); pharmacology (FK8); behavioral sciences, ethics, and jurisprudence (FK9); and research methodology, analysis, and informatics tools (FK10). This guide quotes those names purely as the exam's published structure — the official documents are the authority on what sits inside each.

Two precision notes worth knowing before you buy anything that claims "official weights." First, the Candidate Guide publishes the weights rounded to whole percentages; the Technical Report's Appendix C carries the same 3 × 10 matrix at one-decimal precision (36.2% / 42.0% / 21.8% at the component level). Second, JCNDE publishes no weight for any of the 56 CC areas individually — a product quoting "official" per-topic percentages below the component level is quoting its own estimate, not JCNDE. Dentovio's blueprint-coded cheat sheets are organized around exactly this matrix, and how we weight them reproduces the published table in full and labels which numbers are JCNDE's and which are Dentovio's clearly-marked estimates.

Two planning consequences. First, no single FK area exceeds 12% — the exam punishes candidates who over-invest in a favorite subject and abandon a weak one, because the weights are too flat for any one area to carry you. Second, 200 of the 500 items are case-based (Section 4 plus all of Day 2), so practicing only standalone questions rehearses just three-fifths of the exam. This guide stays out of the clinical content itself — the blueprint is your map of where the questions come from, and the official documents are the authority on what is in each area.

Application

Are you eligible, and how to apply (DENTPIN first)

Everything starts with a DENTPIN — the unique 8-digit identifier the U.S. dental testing ecosystem uses, managed at ADA.org/DENTPIN. Get it before anything else, and get it right: the name on your DENTPIN must exactly match the name on your identification documents, or you will be denied admission at the test center and forfeit your fees. For internationally trained candidates whose documents show name-order or spelling variations, this is the single most expensive clerical trap in the process — your ECE report name must match your DENTPIN too. (The DENTPIN is also the identifier used for ADEA CAAPID and PASS applications later, so this one ID follows you through the whole journey.)

Eligibility runs through one of three lanes:

Your situationWhat establishes eligibility
Current student, CODA-accredited programYour dean (or designee) confirms you are prepared in all applicable disciplines
Former CODA student (not graduated)Only if admitted or conditionally admitted to another CODA program, with a dean letter
CODA graduateADA active/life/retired members: automatic. Others: diploma or degree verification
Graduate or student of a non-CODA program (most internationally trained dentists)Degree confirmed through ECE — see below

Two notes on the table. Graduates of CDAC-accredited Canadian programs are treated as CODA under a reciprocal agreement — you are in the top three rows, not the international lane. And "non-CODA" is about the program's accreditation, not your nationality.

The ECE step (non-CODA candidates). JCNDE names exactly one credential evaluator: Educational Credential Evaluators (ECE). For exam eligibility alone, ECE's U.S. General Report ($110) suffices; the Course-by-Course Report ($199) is also accepted — and most dental schools require Course-by-Course for later advanced-standing applications, so if you already know you are heading to CAAPID, buying the bigger report once can beat buying two. Current students of non-CODA programs additionally need a Certification of Eligibility Form, sent by their program with the university seal and dean's or registrar's signature — mailed to JCNDE, not to ECE. How the ECE → exam → CAAPID sequence stacks into one timeline, and what each stage waits on, is mapped end to end in the international dentists guide.

The 6-month clock. Once your application is processed, you have a 6-month eligibility window to test. Let it lapse untested and the fee is forfeited — each new attempt means a new application and new fees. One 45-day extension is available per application for $150, and only if you have no test appointment scheduled. Do not apply until your documents, finances, and (for international candidates) travel plans can all land inside the window.

Budget

What it costs in 2026 — and why each retake repeats everything

The 2026 fee schedule, from the Candidate Guide:

FeeAmountNotes
Examination fee$890Includes reporting to you, up to 3 jurisdictions requested at application, and your dental program. Up from $880 in 2025.
Non-CODA processing fee$435Applies to candidates from non-CODA programs — bringing the real per-attempt cost to about $1,325 for most internationally trained candidates
INBDE + DLOSCE bundle$1,080Optional bundle with JCNDE's separate clinical judgment exam; saves $470 versus buying both separately. DLOSCE acceptance is state-by-state — check whether your target state uses it before paying for it
Eligibility extension$15045 days, once per application, only with no appointment scheduled
Rescheduling (paid to Prometric)$50 / $70 / $150$50 with 30+ business days' notice, $70 with 5–29, $150 with 1–4. Saturdays and Sundays are not business days
Arriving over 30 minutes late, or no-showFull testing fee forfeited
Extra results report$55Per report
Results audit$105Request within 30 days of the reporting date; takes 4–6 weeks

Two budgeting notes. First, the audit and results-report fees are the 2026 Candidate Guide figures — some JCNDE web pages still showed older, lower amounts when we verified this page, so treat these as recently changed and the Candidate Guide as controlling. Second, and more important: an attempt is consumed the moment you sit down and agree to the confidentiality statement. Fail, and the next attempt is a new application at full price — exam fee, non-CODA fee, and (for many international candidates) another round of travel. The cheapest attempt is the one you are actually ready for.

Scheduling

Booking Prometric: lead times, travel math, and the reschedule tiers

The INBDE is delivered year-round at Prometric test centers in the United States, U.S. territories, and Canada — and nowhere else. There is no remote-proctoring option, and JCNDE's current roadmap does not plan one. If you live outside North America, the exam includes a trip: visa timing, flights, and a stay long enough to cover both test days inside the 7-day window.

JCNDE's own scheduling advice: book 60–90 days before your desired date, because seat capacity fills. Combine that with the 6-month eligibility window and the sequence becomes clear — apply, then book both days immediately when your eligibility is confirmed, not after you feel ready.

Know the change-fee economics before you book:

  • Rescheduling costs $50 with 30 or more business days' notice, $70 with 5–29, and $150 with 1–4 business days — and weekends do not count as business days.
  • Arrive more than 30 minutes late, or fail to show, and you forfeit the full testing fee.
  • If your 6-month window itself is the problem, the $150 / 45-day extension exists — but only once per application, and only while you have no appointment scheduled.
  • Genuine emergencies have a formal path: a written relief request to testingproblems@ADA.org within 5 business days, with documentation.

If test-center mechanics themselves make you anxious, Prometric sells an optional 30-minute dry run called Test Drive (prometric.com/test-drive): you go through real check-in and a generic sample test at a real center. For an international candidate who has never been inside a U.S. testing facility, it is a cheap way to burn off first-time logistics stress — just note it is a paid extra, and generic (not INBDE content).

Scoring

How scoring actually works — and why 75 is not 75%

The INBDE is pass/fail. If you pass, your result says "Pass" — no numeric score, ever. Behind the label, JCNDE scores the exam on a 49–99 scale, and the minimum passing score is 75.

Here is the myth this section exists to kill: a scale score is not a percentage. Scoring 75 does not mean answering 75% of questions correctly, and a 74 does not mean you were "one question away." The INBDE uses a criterion-referenced statistical model (three-parameter IRT — each question is weighted by its measured difficulty, how well it discriminates, and its guessability) and results are equated across test forms, so a slightly harder form and a slightly easier form yield comparable scale scores. Three practical consequences:

  1. There is no penalty for guessing. An unanswered question can only cost you; a guess can only help. Answer all 500.
  2. You cannot compute your own score, and neither can any prep company. Ignore anyone selling a "raw-score-to-75 converter" — JCNDE publishes no conversion table.
  3. Some items do not count at all — the unscored experimental items mixed invisibly into the form — which is one more reason self-assessment mid-exam ("I've missed too many") is unreliable. Keep working.

If you fail, you get real data. A failing report shows your numeric overall scale score plus a performance breakdown across the 3 clinical content areas and 10 Foundation Knowledge areas, with a graphical summary — built for remediation planning. Note the fine print: the pass/fail decision rides solely on the overall score; the area breakdown is diagnostic, not a set of per-area hurdles.

That is the essential mechanics. Everything deeper — release timing and who else sees your results, exactly what pass and fail reports each contain, the attempt history that follows you, and the $105 results audit — lives in the dedicated INBDE results and scoring guide, and this guide's after-you-test section covers the decision fork a result creates.

The data

What the pass-rate data means for your plan

One story dominates the recent numbers: on June 1, 2024, JCNDE implemented a new, harder performance standard. The new standard was set in January 2024 using the Bookmark standard-setting method and approved in May 2024. You can see it land in JCNDE's own Technical Report data — first-time failure in the CODA-accredited cohort went from 0.4% in 2023 to 4.8% in 2024 to 7.2% in 2025, and 2025 is the first complete calendar year under the new standard.

The planning takeaway per persona, using the 2025 figures:

  • CODA/CDAC students: first-attempt failure is 7.2% — low, but eighteen times the 2023 figure. Any "everyone passes, don't overthink it" advice you inherited from someone who tested in 2022–2023 describes an exam that no longer exists.
  • Internationally trained (non-accredited cohort): first-attempt failure was 34.9% — roughly one in three. This is a cohort statistic, not your personal probability, but it is the honest base rate to plan a runway against.
  • Repeat candidates: retake failure was 27.0% in the CODA cohort and 50.5% in the non-accredited cohort. A coin-flip retake rate at ~$1,325 per attempt is the strongest argument in this guide for changing your preparation before changing your test date.

Two label warnings so you read the data the way JCNDE publishes it. "Non-accredited" is JCNDE's cohort label for candidates from non-CODA programs — it is the closest published proxy for internationally trained candidates, but it is not a nationality count. And all of these are failure rates for administrations, not unique people.

The full year-by-year table (2021–2025, both cohorts, first-time and retake) with sourcing lives on one page — we keep it in one place so it can be verified against the Technical Report line by line: INBDE pass rates by cohort.

Strategy

Building the study runway (start with JCNDE's free materials)

Radical honesty first: the best free INBDE prep comes from JCNDE itself, and any prep company that lists its own product ahead of the official materials is showing you its priorities. At JCNDE.ADA.org/INBDE you will find the official INBDE Practice Questions PDF, the "Foundation Knowledge for the General Dentist" document, and the official Acronyms & Abbreviations list. JCNDE's stated position is that textbooks and your lecture notes are the primary study sources — and it endorses no commercial course. None. Not Dentovio, not anyone. Every paid product in this market, ours included, is an unofficial supplement built around the official blueprint.

What differs by persona is the runway, not the destination:

  • Internationally trained candidates: plan in months, not weeks. You are often years past the foundational coursework, possibly studying in a second language, and coordinating the ECE-application-travel sequence in parallel. Dentovio's 3-month and 6-month week-by-week schedules are built for exactly this runway — including pacing the two study-load levels honestly instead of pretending everyone has 40 free hours a week.
  • U.S./Canadian students: your program's curriculum is the core prep, and your dean certifies you are prepared in the applicable disciplines. Your calibration questions are about the format and weighting — especially whether you have practiced case-based blocks at Day 2 length, since 140 case items in one test session is an endurance format no course lecture rehearses.
  • Repeat candidates: your failing score report's breakdown across the 3 clinical content areas and 10 FK areas is your syllabus. Rebuild from what it says, not from what feels weak. JCNDE itself encourages formal remediation before re-examination — the retake failure rates in the previous section show what happens when preparation does not change.

Whatever your lane, get one honest external reading before you book: Dentovio's free readiness mock and the readiness self-check exist to tell you where you stand — the self-check deliberately does not predict a score, because nothing honestly can.

Buying advice

How to evaluate INBDE prep before you pay for it

Start from the fact established in the study-runway section: JCNDE endorses no commercial course, so every paid product in this market is an unofficial supplement competing on quality you have to judge yourself. The good news is that the highest-signal quality checks are things you can verify in minutes, before paying, without taking anyone's word for anything. Six of them:

1. Published verification dates on every factual page. This exam's facts move: the passing standard changed on June 1, 2024; the exam fee moved from $880 to $890 for 2026; the post-5/5 retake wait changed from 12 months to 6 with the 2026 Candidate Guide; and JCNDE's own website carried a stale results-audit fee for months after the Candidate Guide changed it. A resource that cannot tell you when each page was last checked against the current Candidate Guide cannot tell you whether you are studying the current exam. Look for a visible last-verified date and named primary sources — not a copyright year.

2. Blueprint-code mapping. The exam is specified as a published matrix of Foundation Knowledge areas crossed with clinical content components (the blueprint section). Ask whether the product's content and practice items are mapped to those published codes — and whether its "weighting" claims match the published component-level table or silently invent per-topic percentages JCNDE has never released.

3. Case and Day 2 volume. Two hundred of the 500 items are case-based, and Day 2 is 140 case items in one session. A question bank that is overwhelmingly standalone items rehearses three-fifths of the exam and none of its endurance profile. Ask specifically how much full-length, case-block practice at Day 2 length is included.

4. An original-items policy, in writing. Ask the vendor directly whether every item is original and where items are sourced from. As the recalls section explains, "real exam questions" are not an advantage — they are documented misconduct exposure for you, the candidate. A vendor who winks about recalled content is selling you a sanctions risk.

5. Refund and guarantee terms, read before paying. A guarantee is a contract term, not a promise of outcome. Read what actually triggers a refund, what you must prove, and by when — and treat any product that predicts your score or your probability of passing as overpromising, because scoring mechanics make both impossible to compute from outside.

6. A free way to test fit first. You should be able to see the teaching style, the item style, and the interface before money moves. If the only way to evaluate a product is to buy it, that is itself information.

For transparency, Dentovio's own answers to these checks are public: every INBDE surface's verification practice and dates are documented on how this is verified, every practice item is original by policy, and the recommended first step is deliberately the free one — take the readiness mock first, and only then decide whether the full INBDE prep earns a place in your runway. Apply the same six checks to Dentovio that you would apply to anyone else.

The line you must not cross

Recalled exam content: what JCNDE prohibits

The moment you sit down at the test-center computer, you electronically agree to a non-disclosure and confidentiality statement — that act is literally JCNDE's definition of using an attempt. From then on, sharing, memorizing for distribution, or reconstructing exam items is misconduct. That includes posting "what I remember" threads, contributing to recall banks, and trading question lists in group chats — the Candidate Guide explicitly reaches social media and forums.

The Candidate Guide's documented sanction list is not a slap on the wrist: score voiding, waiting periods and testing bans, and possible civil and criminal exposure. Sanctions of this kind put a licensure file at serious risk.

None of those prohibitions cover JCNDE's official practice materials, the published blueprint, textbooks, your lecture notes, or original practice questions written by third parties. That last category is where Dentovio operates and the line we hold: every Dentovio item is an original, exam-style question built from cited public sources — never recalled, reconstructed, or "inspired by" live items. When you evaluate any prep product, ours included, ask the vendor directly whether their items are original and where they are sourced from. A vendor who winks about "real exam questions" is selling you a sanctions risk, not an advantage.

Logistics

Test days: the logistics that lose points

The two-ID rule. Bring two original, physical IDs: a primary government-issued photo ID with your name and signature, and a secondary ID with name and signature (a debit, credit, or library card works). Expired and digital IDs are rejected. And the names must match the name on your DENTPIN exactly — a mismatch means denied admission and forfeited fees, which is the worst-value failure mode this exam offers.

Security screening is real and worth expecting calmly: biometric capture (photo, fingerprint, or palm vein), metal-detector wanding, and inspection of eyeglasses and hair accessories. Jewelry is prohibited except wedding and engagement rings.

In the room:

  • You get two note boards and two markers; they are surrendered or erased at the end of each day.
  • Prohibited: watches, phones, food and drink, translation aids, and dictionaries.
  • On unscheduled breaks (anything outside the scheduled break windows) you cannot access your locker or personal items, cannot eat or drink, and cannot leave the center. Use the scheduled 15/30/15-minute breaks on Day 1 deliberately — eat during the 30.
  • The timer pauses while questions load, so slow screens are not eating your time.

Frame Day 2 as an endurance event. It is "only" 4 hours 15 minutes, but it is 140 case-based items back to back — two 70-item sections of Patient Box work with a single 15-minute break between them. Candidates who have never done a full-length case block at one sitting hit a fatigue wall in Section 6. Rehearse the format at length at least once before the real thing — the Day 2 guide breaks down the pacing math and how to build that rehearsal.

If something goes wrong — illness, a center incident, an emergency — the formal path is a written relief request to testingproblems@ADA.org within 5 business days, with documentation. Vague complaints to the front desk are not the procedure; the email with evidence is.

After you test

What happens after you test

Between finishing Section 6 and seeing a result, there is exactly one productive thing to do: nothing. Results are released only through your DENTPIN account, after JCNDE's quality-assurance checks — within 4 weeks of your exam date, most within 3. JCNDE publishes no release day, time, or cadence, so the weekday patterns traded on forums are anecdotes, not policy. Refreshing the portal does not speed it up.

Then the road forks. A pass shows the word "Pass" and nothing else — no number exists for you to see — and your next moves are in the road ahead. A fail shows your numeric overall scale score plus the 13-area diagnostic breakdown, and your next moves are in the retake playbook. If you believe a result is wrong, the one formal instrument is the $105 results audit, requested within 30 days of the reporting date; audits take about 4–6 weeks, their outcomes are non-appealable, and JCNDE publishes no data on how often they change anything.

Two companion pages carry the depth this summary points at: the results and scoring guide walks through release mechanics, both report types, the audit, and who else sees your results — and the pass-rates page holds the cohort data that keeps any single result, good or bad, in honest context.

If you fail

If you fail: the retake playbook

First, the definition that governs everything: an attempt is used when you are seated at the test-center computer and have electronically agreed to the confidentiality statement. From there, four rules govern your calendar: a minimum 60-day wait between unsuccessful attempts; a maximum of 4 administrations in any 12-month period (a 5th is possible only after 12 months from the first attempt in that window); the 5-year/5-attempt rule — pass within 5 years of your first attempt or 5 attempts, whichever comes first, after which you may test once every 6 months after your most recent attempt; and independence from history — INBDE attempts are counted separately from any prior NBDE Part I/II attempts. If you passed, you may not retake unless a dental board requires it.

Know what is non-appealable before you spend energy appealing it: the 60-day wait, the 4-per-12-months cap, the post-5/5 six-month wait, the non-CODA degree-confirmation policy, audit outcomes, and score adjustments. JCNDE publishes these as final; plan around them rather than against them. (The once-every-6-months rule after the 5/5 limit is itself new with the 2026 guide — the 2025 edition said once every 12 months, and stale copies of the old rule still circulate — the current Candidate Guide is always the controlling text.)

Everything else about recovering from a fail lives on two dedicated surfaces built for exactly that job. The INBDE retake playbook covers what the fail report's 13-area breakdown actually shows, the full re-application mechanics (each retake is a new application at full fees — ~$1,325 for most internationally trained candidates), and a rebuild plan built on published learning-science evidence. The retake calculator turns the rules above into your own earliest eligible retest date and maps your remaining attempts against the caps. One line to carry with you: JCNDE encourages formal remediation before re-examination, and in 2025, 27.0% of CODA-cohort retakes and 50.5% of non-accredited-cohort retakes failed — the 60-day wait is a floor, not a recommendation.

The road ahead

After you pass — and what JCNDE has announced next

A pass is a milestone, not a license. Where it sits next depends on your lane:

  • U.S./Canadian students: the INBDE is one requirement among several — states add their own clinical-exam and other licensure requirements, and those are set state by state. Your school's licensure advising and your target state's board are the authorities on sequencing the rest.
  • Internationally trained dentists: a pass clears the exam requirement many advanced-standing programs set; whether it is required before applying varies by program. ADEA CAAPID for the 2026–27 cycle costs $264 for the first program and $115 for each additional program, individual program requirements (English testing, evaluation type, INBDE timing) vary — ADEA's Program Finder is the authoritative source per program — and your DENTPIN is the identifier CAAPID uses, which is why the name-match discipline from the eligibility section keeps paying off. The full journey — evaluation, exam, applications, advanced standing, licensure — is mapped in our international dentists guide. One narrower door worth knowing about: Minnesota publishes a limited-general-license pathway that some internationally trained dentists use; requirements are specific and change, so verify directly with the Minnesota Board of Dentistry rather than any summary, including ours.
  • Repeat candidates who just passed: note that you may not retake to "improve" — there is no numeric score to improve, and retakes after a pass are barred unless a dental board requires one.

The INBDE is also not the last written exam for everyone. Some states test their own dental law on top of everything above. If your target state is one of them, Dentovio publishes the same source-backed cornerstone treatment for two of those exams: the California Law and Ethics Examination guide and the Florida Laws and Rules exam guide. And if someone in your study circle is on an allied-dental track rather than the dentist track, the California RDA exam guide and the California RDH Law and Ethics guide cover those exams' separate rules — each exam is its own body of law, and none of them borrows from this one.

What JCNDE has announced next — and what it has not. On JCNDE's current published roadmap, a dental practice analysis runs through 2026–2027, subject-matter-expert panels are slated to recommend test-specification updates in 2027, and new performance-standard work follows in 2028 — recommendations, with no published implementation date. No format change has been announced. Multi-stage adaptive testing remains under consideration only, and no remote proctoring is planned. Translation for planners: prepare for the exam as the current Candidate Guide specifies it, and treat anyone converting JCNDE's recommendation calendar into a "new exam in 2027" warning as a rumor to check against JCNDE directly.

This page describes the rules as of its last-verified date. JCNDE changes fees, policies, and standards on its own schedule — before you apply, schedule, or travel, confirm the current requirements at JCNDE.ADA.org, which is the authoritative source this guide is built from, and see how this is verified for the checking practice behind every INBDE page here.

Straight answers

Questions INBDE candidates actually ask

How much does the INBDE cost in 2026?

The 2026 examination fee is $890 (up from $880 in 2025). Candidates from non-CODA-accredited programs — most internationally trained dentists — pay an additional $435 processing fee, bringing the per-attempt total to about $1,325 before travel. An optional INBDE + DLOSCE bundle is $1,080, saving $470 versus buying both separately.

What score do you need to pass the INBDE?

A scaled score of 75 on JCNDE's 49–99 scale. A scale score is not a percentage — 75 does not mean 75% of questions correct, and a 74 does not mean you were one question short. The exam is criterion-referenced and equated across forms, and there is no penalty for guessing. Passers see only "Pass," with no number.

How long does it take to get INBDE results?

Results post to your DENTPIN account within 4 weeks of your exam date; most arrive within 3 weeks. Passing candidates see "Pass" only. Failing candidates receive a numeric overall scale score plus a performance breakdown across 3 clinical content areas and 10 Foundation Knowledge areas.

Can I take the INBDE online or outside the United States?

No. The INBDE is delivered only at Prometric test centers in the US, US territories, and Canada — there is no remote-proctoring option, and JCNDE's published roadmap does not plan one. International candidates must plan travel, visas, and a stay long enough to cover both test days within the 7-day window.

How many times can you take the INBDE?

After an unsuccessful attempt you must wait at least 60 days. You may test at most 4 times in any 12-month period, and you must pass within 5 years of your first attempt or 5 attempts, whichever comes first — after that, you may test once every 6 months. Each retake is a new application at full fees.

Is the INBDE harder than it used to be?

Measurably, yes. JCNDE implemented a new performance standard on June 1, 2024 (set in January 2024 using the Bookmark method and approved in May 2024). First-time failure in the CODA-accredited cohort went from 0.4% in 2023 to 4.8% in 2024 to 7.2% in 2025. Difficulty advice from anyone who tested before mid-2024 describes a different standard — see the full pass-rate data.

What is the INBDE pass rate?

It depends heavily on cohort. In 2025, first-attempt failure was 7.2% in JCNDE's CODA-accredited cohort and 34.9% in the non-accredited cohort; retake failure was 27.0% and 50.5% respectively. The year-by-year table from JCNDE's Technical Report is on our pass-rates page. Note that "non-accredited" is JCNDE's program label, not a nationality count.

Do internationally trained dentists need a credential evaluation for the INBDE?

Yes. All candidates from non-CODA programs must have their degree confirmed through Educational Credential Evaluators (ECE) — the only evaluator JCNDE names. For exam eligibility alone, ECE's U.S. General Report ($110) suffices; the Course-by-Course Report ($199) is also accepted and is what most dental schools require later. The name on the ECE report must exactly match your DENTPIN.

What happens if I miss Day 2 of the INBDE?

Day 2 must occur within 7 days of Day 1, at the same test center. If it does not, you retest at your own expense — which for a non-CODA candidate means another application cycle at about $1,325 plus travel. Book both days as a pair, and treat the Day 2 appointment as immovable.

What does the JCNDE prohibit about recalled exam content?

When you sit for the exam you electronically agree to a nondisclosure and confidentiality statement, and the Candidate Guide prohibits sharing, memorizing for distribution, or reconstructing exam items — explicitly including on social media and forums. Its documented sanctions include score voiding, waiting periods and testing bans, and possible civil and criminal exposure — sanctions of this kind put a licensure file at serious risk. The prohibitions do not cover JCNDE's official practice questions, the published blueprint, textbooks, or original third-party practice items.

What replaced NBDE Part 1 and Part 2?

The INBDE, which launched August 1, 2020; NBDE Part I was discontinued in 2020 and Part II in 2022. The INBDE is a single, integrated, pass/fail exam — so any study advice organized around "Part 1" and "Part 2" predates the current exam and is obsolete. INBDE attempts are also counted independently of any prior NBDE attempts.

Is there a penalty for guessing on the INBDE?

No. The scoring model applies no guessing penalty, so an unanswered question can only hurt you. Answer all 500 items — including the ones that feel impossible, some of which are unscored experimental items you cannot identify anyway.

What ID do I need at the Prometric center?

Two original, physical IDs: a primary government-issued photo ID with your name and signature, plus a secondary ID with name and signature (a debit, credit, or library card qualifies). Expired and digital IDs are rejected, and the name must exactly match your DENTPIN — a mismatch means denied admission and forfeited fees.

Does JCNDE endorse any INBDE prep course?

No — JCNDE endorses no commercial course, Dentovio included. Its stated position is that textbooks and lecture notes are the primary study sources, supported by its own free materials: the official INBDE Practice Questions PDF, the "Foundation Knowledge for the General Dentist" document, and the Acronyms & Abbreviations list at JCNDE.ADA.org. Every commercial product is an unofficial supplement.

How many questions can you get wrong and still pass the INBDE?

There is no published number, and no honest way to compute one. The passing standard is a scaled score of 75, not a raw count: each question carries a different statistical weight, forms are equated so the raw score needed varies by form, some items are unscored experimental questions, and JCNDE publishes no raw-to-scale conversion table. Any "you can miss X questions" figure is invented. The full mechanics are in the results and scoring guide.

Is the INBDE graded on a curve?

No. The INBDE is criterion-referenced: 75 is a fixed standard, and your result does not depend on how other candidates in your session or cycle performed. The standard itself changes only through JCNDE's formal standard-setting process — most recently on June 1, 2024, which is why failure rates moved without the exam being "curved."

How many questions are on Day 1 vs Day 2 of the INBDE?

Day 1 has 360 items — three 100-item standalone sections plus one 60-item case section — across 8 hours 15 minutes of administration. Day 2 has 140 items, all case-based, in two 70-item sections across 4 hours 15 minutes. Day 2 is a different kind of test-taking problem; the dedicated Day 2 guide covers its pacing and endurance demands.

Does a passing INBDE result expire?

JCNDE does not publish an expiration date for a passing result. Individual dental boards and advanced-standing programs may impose their own recency requirements, though, so verify with your target state board or program directly. Note also that you may not retake a passed INBDE unless a dental board requires it — there is no numeric score to "refresh."

What time of day do INBDE results come out?

JCNDE publishes no release day, time, or cadence — only that results post to your DENTPIN account within 4 weeks of the exam date, most within 3 weeks, after quality-assurance checks. Weekday patterns reported on forums are anecdotes, not policy. Release mechanics, both report types, and the results audit are covered in the results guide.
