There is more than one MFDS Part 1 route in October 2026. The legacy Edinburgh and Glasgow route lists 6 October, RCS England's final legacy sitting is 20 October, and the new tri-collegiate examination begins on 28 October. A resource labelled simply "MFDS 2026" is not enough to establish which assessment it prepares you for.
These dates and the format distinctions below were checked against college information on 6 September 2026. The published application deadlines for these October Part 1 sittings have already passed. This is a preparation and route-checking guide, not an invitation to make a new booking.
Start with the confirmation, not the name on a revision website
Find the administering organisation, examination date and version in the candidate confirmation. Then open the official syllabus and instructions for that route. The RCS England entry specifically labels its 20 October legacy sitting as resit-only, so it should not be presented as another first-time entry option.
The RCSEd examination calendar lists the legacy Part 1 sitting on 6 October 2026. RCS England's Part 1 page distinguishes its legacy examination from the new format. The new-examination announcement gives 28 October 2026 for the first revised Part 1 sitting.
A candidate can use the same broad dental knowledge across routes while still needing different format practice and curriculum checks. The mistake is assuming that overlap makes the versions interchangeable.
The format differences that affect practice
| October 2026 route | Written format in the published information | Revision implication |
|---|---|---|
| Legacy Edinburgh and Glasgow | A three-hour paper with 180 single best answer questions | Match timed practice to this route, not the England legacy count |
| Legacy RCS England | A three-hour paper with 150 single best answer questions, remotely delivered | Use the corresponding syllabus and remote-examination instructions |
| New tri-collegiate MFDS | 180 single best answer questions across two papers of 90, each lasting two hours | Practise the revised structure and check the assessment-centre instructions |
The legacy Edinburgh and Glasgow description comes from RCSEd's Part 1 details. The England and new-format details come from the current RCS England page. All were checked on 6 September 2026.
The new examination is computer-delivered at designated assessment centres. In this context, "online" does not mean the candidate can sit it from home. The college announcement explicitly distinguishes centre-based delivery from remote sitting.
Do not overlook what happens after Part 1
The transition concerns the pathway as well as the written paper. RCS England's transition guidance explains that the first new-format Part 2 is planned for March 2027 and requires a pass in the new Part 1.
A legacy Part 1 pass does not transfer automatically into the new route. The remaining legacy Part 2 opportunities and any individual conditions therefore matter before assuming that passing an October paper completes the planning problem.
Use the Dental Examinations Executive's transition information alongside the relevant college instructions. Where a candidate has an existing pass, exemption or unusual examination history, obtain clarification from the administering body rather than treating a commercial resource's summary as an eligibility decision.
Audit the resources you already own
Open the resource's sample questions, contents and current format description. Ask which syllabus it names, when the material was last mapped and which examination timing it uses. A large question count cannot answer those questions by itself.
Classify the material into three groups: clearly relevant content, potentially relevant content requiring a syllabus check, and format-specific material that does not match the sitting. This is an original resource-review method, not an assertion that older learning materials have become useless.
A well-explained clinical question may remain educationally valuable even when its mock-paper setting is wrong for the new route. Keep the useful content and change the rehearsal conditions. Conversely, changing a timer does not correct missing curriculum coverage.
A fictional candidate preparing for 28 October
Imagine a dentist who owns a legacy question bank and has a confirmed place in the new examination. They recognise many topics in the revised syllabus but have been practising one uninterrupted three-hour paper.
The first intervention is not necessarily another purchase. It is a documented comparison between the official syllabus and the resources already available. The candidate can then identify missing areas and rehearse the new paper structure using appropriately selected questions.
For each gap, choose the smallest useful addition: an official example, a focused reference chapter, a relevant teaching session or targeted question practice. Buying a second comprehensive bank without checking overlap can add work while leaving the actual gap unresolved.
A fictional candidate on the legacy route
A candidate sitting the England legacy examination needs the England format, not a new-format mock simply because it appears more recent. They should also understand the remaining route to Part 2 before interpreting a Part 1 pass as an unrestricted future option.
Someone sitting the Edinburgh and Glasgow legacy route should not adopt the England question count from a generic comparison page. The similar qualification name is precisely why the administering body's instructions must remain visible in the study plan.
These scenarios illustrate resource selection. They do not claim that a particular candidate can change route, obtain an exemption or access another sitting after the published deadline.
Where iatroX can help, and what still needs checking
This article is published by iatroX and includes its question-bank and tutoring tools in the resource discussion. As of September 2026, the platform provides adaptive question practice, spaced repetition, Socratic Tutor and study planning.
For an MFDS candidate, the useful task is to explore an attempted question, identify the misconception and choose relevant follow-up practice. That does not establish that every official syllabus item has been independently audited against every question in the bank. Check the current product description and sample content against the exact route.
For the new-format candidate, prioritise the revised official syllabus and format, then use suitable learning resources for identified gaps. For the legacy candidate, preserve the applicable college's requirements. For someone without an October booking, begin with the next official application opportunity rather than assuming this guide establishes availability.
The appropriate verdict is therefore route-specific: a resource is useful when its content and practice conditions fit the candidate's assessment, not simply when its title contains the latest year.
Frequently asked questions
Is there one MFDS Part 1 date in October 2026?
No, the published routes list different dates for the legacy examinations and the new tri-collegiate examination. Check the administering organisation and the candidate confirmation.
Can a legacy Part 1 pass be carried into the new MFDS route?
The published transition information does not permit that automatic transfer. Check the remaining legacy pathway and any individual eligibility question with the examination body.
Does the new online examination mean I can sit it at home?
No, the first new-format sitting is delivered at designated assessment centres. Use the instructions for the confirmed route rather than assuming remote delivery.
