Why "MJDF Part 1" Is a Legacy Term
If you've searched for "MJDF Part 1," you've landed on a name that technically no longer describes a live examination. The Royal College of Surgeons of England ran its final sitting of MJDF Part 1 in October 2020. Since then, the Dental Examinations Executive - a joint body representing the Royal Colleges of Surgeons of England and Edinburgh together with the Royal College of Physicians and Surgeons of Glasgow - has run a single, unified tri-collegiate examination in its place: MFDS Part 1.
In practice, this means candidates today prepare for and sit MFDS Part 1, even though the old acronym still circulates in forums, job adverts, and casual conversation among dentists. The underlying purpose hasn't changed: it's still a knowledge-based gateway exam confirming that a dentist has the clinical foundation expected before progressing further in UK dental training. This site treats "MJDF Part 1" as shorthand for that successor exam, and every fact below reflects the current format rather than the discontinued one.
Exam Format: What the Test Actually Looks Like
The current exam is a computer-based test delivered at assessment centres. It consists of 180 single-best-answer questions, divided into two papers of 90 questions each. Each paper is allotted two hours, with a short break scheduled between the two sittings. There is no negative marking, which changes how you should approach uncertain questions - guessing costs you nothing, so leaving an answer blank is always the wrong move.
Because the exam is single-best-answer rather than extended matching or free text, the skill being tested is rapid clinical reasoning under a fixed time budget rather than essay-style explanation. With 90 questions in 120 minutes per paper, you have roughly 80 seconds per question on average - some will take ten seconds, others will need three minutes of working through a clinical vignette, so pacing across the paper matters as much as raw knowledge.
Key Takeaway
Since there's no negative marking, never leave a question unanswered - an educated guess has a better expected outcome than a blank response.

Complete Difficulty Guide 2026. And if you're trying to work out what score you actually need to clear the bar, MJDF Part 1 Passing Score 2026: Exactly What You Need to Pass walks through how the pass mark is determined.
Who Can Sit the Exam
Eligibility isn't open to anyone with an interest in dentistry - it's tied to where you are in your professional journey. To sit the exam you generally need:
- An acceptable primary dental qualification recognised by the awarding colleges.
- Registration with a recognised dental regulator in the jurisdiction where you practise.
- Sufficient clinical experience to meet Dental Core Training outcomes - this is not a exam you sit straight out of dental school with zero clinical hours.
- English language proficiency comparable to an IELTS score of 7, which matters particularly for internationally trained dentists.
These requirements exist because the exam assumes a working clinical vocabulary and enough hands-on exposure to interpret case-based questions correctly, not just textbook recall. A full breakdown of documentation, timelines, and edge cases (like partial qualifications or overseas degrees) is covered in MJDF Part 1 Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Blueprint: 19 Domains You're Tested On
The exam blueprint spreads 180 questions across 19 distinct domains, each with its own approximate question range. Some domains are broad clinical knowledge areas; others are professionalism and safety-focused. Here's the full list as it's structured:
| Domain | Approx. Question Range |
|---|---|
| Professional Knowledge and Behaviour | 2-4 |
| Patient-centred Care | 1-3 |
| Teamworking | 2-4 |
| Clinical and Patient Safety | 3-5 |
| Underpinning Clinical Knowledge | 20-30 |
| Clinical Examination and Assessment | 20-30 |
| Diagnosis, Patient Management and Treatment Planning | 20-30 |
| Emergency Care (Management of Dental and Facial Injuries) | 6-10 |
| Preventative Care and Maintenance of Oral Health | 6-10 |
| Restorative Dentistry | 6-10 |
| Orthodontics | 6-10 |
| Oral Surgery | 6-10 |
| Paediatric Dentistry | 6-10 |
| Special Care Dentistry | 6-10 |
| Oral Medicine | 6-10 |
| Oral and Maxillofacial Pathology | 4-6 |
| Oral and Maxillofacial Radiology | 6-10 |
| Oral Microbiology | 6-10 |
| Dental Public Health & Epidemiology | 6-10 |
Notice how uneven this list is. Four domains - Professional Knowledge and Behaviour, Patient-centred Care, Teamworking, and Clinical and Patient Safety - together contribute fewer questions than any single one of the "big three" clinical domains. That imbalance should directly shape how you allocate revision time. For a domain-by-domain walkthrough with what to actually study inside each one, see MJDF Part 1 Exam Domains 2026: Complete Guide to All 19 Content Areas.
The Three Domains That Dominate the Paper
Three domains sit well above the rest in weighting, each contributing 20-30 questions - meaning together they can account for more than a third of the entire exam. Mastering these three is non-negotiable.
Underpinning Clinical Knowledge
This is the foundational science and applied clinical knowledge domain - the "why" behind clinical decisions rather than the decision itself.
- Expect questions that test mechanism and rationale, not just fact recall.
- Weak foundational knowledge here tends to cost marks across other domains too, since it underpins reasoning everywhere else.
Clinical Examination and Assessment
Questions here test your ability to interpret clinical presentations, histories, and examination findings correctly.
- Vignette-style questions are common - read the clinical scenario carefully before jumping to the answer options.
- This domain rewards structured examination habits, not memorised checklists alone.
Diagnosis, Patient Management and Treatment Planning
This domain tests judgment: given a diagnosis, what's the correct next step or the best overall treatment pathway.
- Questions often present multiple plausible options - the "best" answer, not just a "correct" one, is what's being tested.
- Expect overlap with restorative, oral surgery, and paediatric content applied through a management lens.
Because these three domains are so heavily weighted, a structured study guide that sequences them correctly matters more than trying to cover all 19 domains evenly. MJDF Part 1 Study Guide 2026: How to Pass on Your First Attempt lays out one practical sequencing approach.
Attempts, Retakes, and the Route to Part 2
Candidates are permitted four attempts at Part 1. This is a hard ceiling, so treat each sitting seriously rather than as a low-stakes practice run. If you pass Part 1, the clock starts on a separate constraint: Part 2 must be passed within four years of your Part 1 pass. That window can feel generous early on, but clinical rotations, job changes, and life events shrink it faster than most candidates expect.

Who Actually Asks for This on a CV
This qualification tends to surface as a preferred or required line item in job postings for dental core training posts, foundation-adjacent roles, and positions where employers want early confirmation of broad clinical competency before a dentist takes on more independent responsibility. It's also commonly used by internationally qualified dentists as a recognised UK-relevant benchmark alongside their primary qualification and regulator registration.

And if you want context on how holding this credential tends to affect earning potential and career trajectory, MJDF Part 1 Salary Guide 2026: Complete Earnings Analysis goes through that qualitatively.
Turning the Blueprint Into a Study Plan
Generic study techniques - spaced repetition, timed question blocks, active recall - only help if they're mapped onto this exam's actual weighting. Given that three domains alone can represent over a third of the paper, a sensible approach front-loads Underpinning Clinical Knowledge, Clinical Examination and Assessment, and Diagnosis, Patient Management and Treatment Planning early, then works through the mid-weighted clinical domains (Restorative Dentistry, Oral Surgery, Orthodontics, Paediatric Dentistry, Special Care Dentistry, Oral Medicine, Radiology, Microbiology, Emergency Care, Preventative Care, and Public Health, each at 6-10 questions), before finishing with the lighter professionalism domains.
Foundations first
- Underpinning Clinical Knowledge and Clinical Examination and Assessment, since later domains build on this reasoning.
Mid-weight clinical domains
- Work through Restorative Dentistry, Oral Surgery, Orthodontics, Paediatric Dentistry, and Oral Medicine in rotation, using timed single-best-answer practice sets.
Integration and lighter domains
- Diagnosis, Patient Management and Treatment Planning tied back to earlier content, plus a pass through Professionalism, Teamworking, and Patient Safety questions.
Full-length timed mock papers under the actual two-paper, no-negative-marking conditions are the closest simulation you can build yourself, and running through the practice tests on MJDF Part 1 Exam Prep lets you rehearse the pacing before exam day rather than discovering it mid-paper. A condensed final-week reference is also useful - MJDF Part 1 Cheat Sheet 2026: One-Page Review of Must-Know Facts is built for exactly that last-mile review.
Frequently Asked Questions
No. The Royal College of Surgeons of England held its last MJDF Part 1 sitting in October 2020. The current tri-collegiate equivalent, developed by the Dental Examinations Executive, is MFDS Part 1, and that's what candidates actually sit today.
There are 180 single-best-answer questions split into two papers of 90 questions each. Each paper runs for two hours, with a short break between the two sittings, and there's no negative marking.
Candidates have four attempts at Part 1. Once you pass, Part 2 must be completed within four years of that Part 1 pass, so it's worth planning the full pathway rather than one exam at a time.
Underpinning Clinical Knowledge, Clinical Examination and Assessment, and Diagnosis, Patient Management and Treatment Planning are the three largest domains, each contributing 20-30 questions out of 180.
You need an acceptable primary dental qualification, registration with a recognised dental regulator, sufficient clinical experience meeting Dental Core Training outcomes, and English proficiency comparable to IELTS 7.
