MJDF Part 1 Pass Rate 2026: What the Data Shows

TL;DR
  • No official numeric pass rate is published for MJDF Part 1 - treat any specific percentage you see elsewhere with caution.
  • The exam is 180 single-best-answer questions across two 90-question, two-hour papers, with no negative marking.
  • Underpinning Clinical Knowledge, Clinical Examination and Assessment, and Diagnosis, Patient Management and Treatment Planning carry 20-30 questions each - the...
  • You get four attempts at Part 1, and Part 2 must be passed within four years of passing Part 1.

Why There's No Official Published Pass Rate

Anyone searching for an "MJDF Part 1 pass rate" quickly runs into a problem: the exam most people now sit under that search term is not the exam that historically carried the MJDF Part 1 name. The Royal College of Surgeons of England ran its final sitting of the original MJDF Part 1 in October 2020. Since then, the commercially relevant exam that candidates prepare for is the unified tri-collegiate MFDS Part 1, developed by the Dental Examinations Executive on behalf of the Royal Colleges of Surgeons of England and Edinburgh and the Royal College of Physicians and Surgeons of Glasgow.

That handover matters for anyone chasing pass-rate statistics. The three colleges involved do not publish a rolling, sitting-by-sitting pass percentage in the way some other professional exams do. If you see a specific number quoted online - "X% pass rate" - treat it with suspicion, because it is often lifted from an unrelated credential that happens to share the same acronym. This article sticks to what is verifiably true of the exam itself: its structure, its weighting, its attempt limits, and the eligibility rules that shape who actually sits it.

If you want the fuller background on how this exam is positioned and who it's for, the What Is MJDF Part 1? overview and the MJDF Part 1 Meaning explainer are useful starting points before you get into pass-rate speculation.

The honest starting point: Instead of chasing a published percentage, focus on the structural factors that actually determine whether an individual candidate passes - question format, blueprint weighting, and attempt limits. Those are documented; a public pass rate is not.

What the Exam Format Tells You About Difficulty

Format shapes outcomes as much as content does. MJDF Part 1 (in its current MFDS Part 1 form) is delivered as 180 single-best-answer questions, split into two papers of 90 questions each, with two hours allowed per paper and a short break between them. There is no negative marking, which is a meaningful structural detail: guessing carries no penalty beyond the opportunity cost of time, so leaving a question blank is never the better option compared to making an educated guess.

This single detail changes exam strategy. Candidates who understand there's no negative marking can move through single-best-answer items more decisively, flagging genuinely uncertain questions for review rather than second-guessing every answer they're not 100% sure of. Time management across two 90-question, two-hour papers becomes the bigger risk factor than the marking scheme itself.

For a deeper breakdown of exactly how many marks you need and how the pass mark is typically set relative to question difficulty, see MJDF Part 1 Passing Score 2026: Exactly What You Need to Pass.

Key Takeaway

With no negative marking across 180 questions, never leave an answer blank. Every unanswered single-best-answer item is a guaranteed zero, while a guess still carries a chance of being correct.

The Blueprint Weighting That Decides Most Outcomes

The single biggest lever on any individual's result is how well their preparation matches the exam's blueprint weighting. Three domains dominate the paper, each carrying 20-30 questions out of the 180 total:

Underpinning Clinical Knowledge

Foundational science and clinical theory that underpins almost every other domain on the paper.

  • 20-30 questions - one of the three largest content blocks

Clinical Examination and Assessment

History-taking, examination technique, and interpreting clinical findings correctly.

  • 20-30 questions - weighted equally with Underpinning Clinical Knowledge

Diagnosis, Patient Management and Treatment Planning

Turning examination findings into a defensible diagnosis and treatment plan.

  • 20-30 questions - the third of the three largest blueprint ranges

Together, these three domains alone can account for 60-90 of the 180 questions - potentially half the paper. Everything else on the blueprint sits in smaller bands: mid-weight clinical domains such as Emergency Care (Management of Dental and Facial Injuries), Preventative Care and Maintenance of Oral Health, Restorative Dentistry, Orthodontics, Oral Surgery, Paediatric Dentistry, Special Care Dentistry, Oral Medicine, Oral and Maxillofacial Radiology, Oral Microbiology, and Dental Public Health & Epidemiology each carry 6-10 questions. Professional and behavioural domains - Professional Knowledge and Behaviour, Patient-centred Care, Teamworking, and Clinical and Patient Safety - carry smaller allocations of 2-5 questions each, plus Oral and Maxillofacial Pathology at 4-6 questions.

Domain TierExample DomainsQuestion Range
Highest weightUnderpinning Clinical Knowledge; Clinical Examination and Assessment; Diagnosis, Patient Management and Treatment Planning20-30 questions each
Mid weightEmergency Care; Restorative Dentistry; Orthodontics; Oral Surgery; Paediatric Dentistry; Special Care Dentistry; Oral Medicine; Radiology; Microbiology; Public Health & Epidemiology; Preventative Care6-10 questions each
Lower weightOral and Maxillofacial Pathology4-6 questions
Lowest weightProfessional Knowledge and Behaviour; Patient-centred Care; Teamworking; Clinical and Patient Safety2-5 questions each

A candidate who ignores this weighting - spending equal time on Oral Microbiology and Diagnosis, Patient Management and Treatment Planning - is misallocating study hours relative to marks available.

Eligibility Rules That Shape Who Sits and Who Passes

Pass outcomes are also shaped upstream, before anyone even opens a question bank. To be eligible to sit MJDF Part 1, candidates need an acceptable primary dental qualification, registration with a recognised dental regulator, sufficient clinical experience to meet Dental Core Training outcomes, and English language proficiency comparable to IELTS 7. Candidates who sit the exam without solid clinical grounding - for instance, before accumulating enough hands-on experience toward Dental Core Training outcomes - are working against themselves on the Clinical Examination and Assessment and Diagnosis, Patient Management and Treatment Planning domains, since those questions are written to test applied judgement rather than pure recall.

The full eligibility checklist, including how the English-language requirement is assessed and what counts as sufficient clinical experience, is covered in MJDF Part 1 Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Attempt structure matters for outcomes: Candidates have four attempts at Part 1. That ceiling means a poor first attempt isn't fatal, but it also means repeated unsuccessful attempts without changing preparation strategy will eventually run out the clock. Treat each attempt as a genuine strategic checkpoint, not just a resit.

Where Candidates Typically Lose Marks

Without a published item-level breakdown, it's not possible to state exactly which domain generates the most failed questions. What can be said qualitatively, based on the exam's own design, is this: the domains with the largest question counts are also the domains that test integrated clinical reasoning rather than isolated facts. Underpinning Clinical Knowledge, Clinical Examination and Assessment, and Diagnosis, Patient Management and Treatment Planning all require candidates to synthesise information - a symptom pattern, a radiographic finding, a patient history - into a single best answer among plausible distractors.

This is different from domains like Oral Microbiology or Oral and Maxillofacial Pathology, where questions are more likely to hinge on discrete factual recall. Candidates who rely purely on memorised facts tend to underperform on the reasoning-heavy domains precisely because those questions are constructed to reward applied clinical judgement over rote memory.

A Prep Approach Mapped to Exam Weighting

Generic study advice - spaced repetition, timed practice blocks, active recall - only helps if it's pointed at the right domains in the right order. Given that three domains alone account for up to half the paper, a sensible allocation of preparation weeks looks like this:

Weeks 1-3

Underpinning Clinical Knowledge and Clinical Examination and Assessment

  • Build the foundational base these two 20-30 question domains rest on
  • Practise question sets under two-hour, 90-question timed conditions to simulate paper pacing
Weeks 4-5

Diagnosis, Patient Management and Treatment Planning

  • Work through case-style single-best-answer items that combine history, examination, and diagnosis
  • Cross-reference with the other two highest-weighted domains rather than studying in isolation
Weeks 6-7

Mid-weight clinical domains

  • Cover Emergency Care, Restorative Dentistry, Orthodontics, Oral Surgery, Paediatric Dentistry, Special Care Dentistry, Oral Medicine, Radiology, Microbiology, and Public Health & Epidemiology
  • Allocate roughly proportional time given each carries 6-10 questions
Week 8

Professional and pathology domains, plus full mocks

  • Finish Professional Knowledge and Behaviour, Patient-centred Care, Teamworking, Clinical and Patient Safety, and Oral and Maxillofacial Pathology
  • Run full 180-question timed mocks with no negative marking rules applied, exactly as on exam day

For a longer-form, first-attempt-focused version of this plan, see MJDF Part 1 Study Guide 2026: How to Pass on Your First Attempt. You can also run full-length timed mocks against the blueprint weighting on our MJDF Part 1 practice test platform to see how your accuracy holds up across all 19 domains before exam day.

Attempts, Retakes, and the Four-Year Clock

Two attempt-related rules directly influence long-term pass outcomes even though they don't appear in any pass-rate statistic. First, candidates have four attempts at Part 1 - a hard ceiling that should inform how aggressively you prepare for each sitting rather than treating early attempts as low-stakes trial runs. Second, once Part 1 is passed, Part 2 must be passed within four years. That four-year window means the timing of your Part 1 pass has downstream consequences for how much runway you have to prepare for Part 2, particularly if clinical rotations or Dental Core Training commitments limit your available study time in certain years.

Scheduling around these constraints is worth planning early. Testing windows and registration deadlines are detailed in MJDF Part 1 Exam Dates 2026: Testing Windows, Deadlines & Scheduling, and the full cost breakdown across attempts is covered in MJDF Part 1 Certification Cost 2026: Complete Pricing Breakdown.

Key Takeaway

Plan your Part 1 attempt timing with the four-year Part 2 clock in mind. Passing Part 1 early in your training window gives you more flexibility to schedule Part 2 preparation around clinical commitments.

Beyond the exam itself, it's worth understanding what passing actually unlocks.
