GDC ORE Part 1 vs Part 2 — Key Differences Every Candidate Must Know

The GDC Overseas Registration Examination is divided into two distinct parts — and they test completely different skills. Part 1 is a written examination testing basic dental sciences, while Part 2 assesses clinical competence through practical OSCE stations. Understanding how they differ is not just useful background information: it is essential to planning your preparation strategy, managing your finances, and setting realistic expectations for your journey towards GDC registration.

What Does ORE Part 1 Test?

The ORE Part 1 is entirely academic in nature. It tests your knowledge of the basic dental and medical sciences that underpin safe dental practice, rather than your ability to perform clinical procedures. The ten knowledge areas covered include Head & Neck Anatomy, Physiology & Biochemistry, Microbiology & Immunology, General and Oral Pathology, Human Disease, Pharmacology & Therapeutics, Dental Materials Science, Oral Biology, Radiology & Radiological Protection, and Behavioural Sciences & Clinical Practice.

Questions are in single best answer format — one stem question with four to five options, from which you must select the single best answer. The distractors are deliberately plausible. The examination rewards precise factual recall and the ability to distinguish between similarly correct-sounding options. Clinical experience helps to contextualise some questions but it does not substitute for theoretical knowledge: a highly experienced clinician who has not revised the basic sciences will struggle on Part 1.

For a complete breakdown of every topic, see our GDC ORE Part 1 Syllabus guide.

What Does ORE Part 2 Test?

ORE Part 2 is an Objective Structured Clinical Examination (OSCE). Candidates rotate through approximately 14 clinical stations, each lasting around 15 minutes, and are marked by examiners directly on their performance at each station. The focus shifts entirely from theoretical recall to clinical competence — how you examine a patient, communicate with them, plan treatment, and perform or demonstrate practical skills.

Typical OSCE station types in Part 2 include: patient examination and diagnosis, treatment planning (presenting and justifying a treatment plan to an examiner), radiograph interpretation (identifying pathology and explaining findings), practical skills (such as matrix placement, impressions, or periodontal charting on typodont models), medical emergency management, communication with simulated patients, ethical scenarios and consent discussions, and record-keeping review.

Part 2 is assessed globally — your score is based on performance across all stations combined, rather than requiring a pass on each individual station. This means a particularly strong performance in some areas can compensate for a weaker performance in others, which differs from the per-paper pass requirement of Part 1.

Which Part Is Harder?

This is one of the most frequently asked questions among ORE candidates, and there is no single answer — it depends significantly on your background and current clinical situation.

Part 1 is harder for most candidates, as evidenced by the pass rate data. The breadth of academic content is enormous — ten knowledge areas covering everything from biochemistry and physiology to legislation and pharmacology. Many overseas dentists trained in clinical-focused curricula find that their basic science knowledge has faded substantially since graduating, and rebuilding it to the level required by the ORE takes considerable time and effort.

Part 2, however, presents its own distinct challenges. For candidates who have not been in recent clinical practice — or who have never worked in a UK dental setting — the OSCE format, communication style expected with UK patients, and specific protocols for the UK context (cross-infection control to HTM 01-05, GDC Standards, UK drug formulary choices) can be unfamiliar and disorienting. Candidates who have been in active clinical practice frequently find Part 2 more accessible, but those who have been out of dentistry for a period, or who are from systems with different clinical norms, may struggle.

Do You Have to Pass Part 1 Before Part 2?

Yes — passing all five papers of ORE Part 1 is a prerequisite for sitting ORE Part 2. There is no pathway that allows candidates to skip or bypass Part 1. Candidates who have passed only some Part 1 papers are not eligible for Part 2 — they must first complete all remaining Part 1 papers.

Importantly, there is no expiry date on Part 1 passes. Once you have passed all five Part 1 papers, your Part 1 pass is permanent — you can proceed to Part 2 at any subsequent sitting without any time limit. Candidates who passed Part 1 several years ago and were delayed in sitting Part 2 (for financial, personal, or immigration reasons) do not need to resit Part 1.

How Long Is the Gap Between Part 1 and Part 2?

There is no minimum required waiting period between passing Part 1 and sitting Part 2. Candidates who pass their final Part 1 paper in January can, in theory, sit Part 2 at the next available sitting in September of the same year — provided they are registered with the GDC as eligible and have met any other application requirements.

In practice, however, most candidates take between six and eighteen months between completing Part 1 and sitting Part 2. The primary reasons for this gap are preparation time (Part 2 requires different skills and often a period of clinical observation in a UK dental practice), the administrative process of applying, and the need to find a placement or honorary contract to develop familiarity with UK clinical practice.

Some preparation course providers specifically recommend that candidates undertake a period of clinical observation or honorary contract in a UK practice before sitting Part 2, both to develop familiarity with UK clinical standards and to build confidence in the OSCE format. The GDC does not mandate this, but many successful Part 2 candidates credit this experience as important to their preparation.

Are There Any Exemptions from the ORE?

The GDC has specific eligibility criteria for the ORE. Not all overseas-qualified dentists are eligible to sit the examination — some candidates may be eligible via alternative registration routes (such as the Mutual Recognition Agreement, or EEA qualification routes that applied prior to changes following the UK's departure from the European Union).

For candidates who are eligible, there are currently no exemptions from individual parts of the ORE based on qualifications or experience alone. Candidates must pass both Part 1 and Part 2 in full to become eligible for GDC registration via the ORE route. The GDC website is the definitive source for current eligibility requirements, as these are subject to change.

Some candidates from countries with which the UK has mutual recognition agreements may have an alternative registration pathway that bypasses the ORE entirely. Candidates should check their eligibility on the GDC website before committing to ORE preparation.

Preparing for Both Parts

Part 1 Preparation

Part 1 requires a structured academic revision programme covering all ten knowledge areas, with an emphasis on SBA question practice. Allow a minimum of three to six months of dedicated preparation. See our complete guide to passing ORE Part 1 for a detailed strategy, and our preparation timeline article to work out how long you specifically need.

Part 2 Preparation

Part 2 preparation is fundamentally different from Part 1. It requires clinical exposure, OSCE technique practice, and familiarity with UK-specific protocols. Key preparation activities include: undertaking a clinical attachment or honorary contract in a UK dental practice, attending Part 2 preparation courses (which usually include mock OSCE sessions with structured feedback), revising UK clinical guidelines (NICE, GDC Standards, HTM 01-05, BNF for dentists), practising communication skills for OSCE stations with simulated patients, and reviewing dental radiograph interpretation systematically.

How OREPass Helps With Part 1

OREPass is purpose-built for ORE Part 1 preparation. The platform provides a comprehensive question bank of 7,000+ GDC-aligned SBA questions covering all ten knowledge areas, full timed mock exams replicating the real paper format, topic-by-topic performance analytics, a predicted score widget, and an AI study tutor that can explain concepts and work through questions with you.

OREPass does not cover Part 2 content — for OSCE preparation, dedicated clinical courses and attachments are more appropriate. But for Part 1, it is the most efficient way to build both knowledge and exam technique.
