EDAIC Part 1 vs Part 2: The Key Differences

If you are mapping out your route to the European Diploma in Anaesthesiology and Intensive Care, the first thing worth getting straight is edaic part 1 vs part 2 — because the two halves of the diploma test you in genuinely different ways. Part 1 is a written, machine-marked examination of what you know; Part 2 is a structured oral examination of how you think and apply it at the bedside. Understanding that distinction early shapes how you study, how long you allow, and where you put your energy.

This article is the bridge between the two. It walks through what each part assesses, how they are marked, how much preparation each tends to demand, and the perennial question of whether Part 2 is really the harder of the two. If you want the fine-grained mechanics of either half afterwards, follow the internal links into the dedicated format guides as you go.

The shape of the diploma: two parts, two skills

The EDAIC is awarded by ESAIC (the European Society of Anaesthesiology and Intensive Care) and is built as a sequential, two-stage assessment. You sit Part 1 first; only once you have passed it can you progress to Part 2. They are not two attempts at the same thing — they are two complementary tests of competence.

• Part 1 (Part I) is a written examination. It checks the breadth and depth of your underpinning knowledge across basic sciences and clinical anaesthesia.
• Part 2 (Part II) is a structured oral examination — the SOE, or viva. It checks whether you can reason out loud, justify a plan, and manage clinical scenarios under questioning.

A useful mental model: Part 1 asks "Do you know it?" and Part 2 asks "Can you use it when a patient and an examiner are both in front of you?" That is the heart of the difference between edaic part 1 and 2, and almost everything else follows from it. For a complete orientation to the first hurdle, the EDAIC Part 1 complete preparation guide is the natural companion to this piece.

EDAIC Part 1 vs Part 2 at a glance

Here is the side-by-side comparison. Treat the qualitative descriptions as the durable facts, and always confirm the live cycle details on the official ESAIC/EDAIC (myESAIC) website, since dates, fees and centres change year to year.

The structural takeaway is simple: the two parts share a syllabus and a philosophy of standard-setting, but they sample your competence through completely different instruments — one written and objective, one spoken and interactive.

What Part 1 actually tests

Part 1 is the written stage, and it is built from two papers.

Paper A — Basic Sciences

Paper A covers the foundations: anatomy, physiology, biochemistry, pharmacology, physics and clinical measurement, equipment, and statistics. This is the paper where a precise, almost mechanical command of detail pays off — the kind of thing where knowing the difference between two isomers or the assumptions behind a statistical test earns marks. If pharmacology or physiology are your soft spots, our high-yield pharmacology topics and high-yield physiology topics round-ups are good places to concentrate revision.

Paper B — Clinical Anaesthesia and Intensive Care

Paper B moves into clinical territory: regional anaesthesia, special and sub-specialty anaesthesia, intensive care, emergency medicine, and pain. It is still a written, knowledge-based paper, but the content is the clinical material you will later be expected to reason with in Part 2. Candidates who find intensive care a weak link should spend dedicated time there — see our intensive care for Paper B breakdown.

For a full anatomy of the two papers — timing, how the content is split, and how to pace yourself — read the dedicated Part 1 format guide to Paper A and Paper B. And if you simply want to see where this stage sits in your overall plan, the /edaic-part-1 hub page pulls the essentials together.

The MTF format and why it changes your tactics

Part 1 uses MTF — Multiple True/False. Each item is a stem followed by five statements, labelled A to E, and you judge each statement independently as true or false. There is no "single best answer"; every one of the five is a separate true-or-false decision.

The single most important tactical fact: there is no negative marking. Negative marking was removed in 2014. A correct statement scores, and a wrong or blank statement scores zero — there is no penalty for guessing. The practical consequence is that you should answer every statement, leaving nothing blank, because a blank can only ever score zero whereas a considered guess has a real chance of scoring. This is exactly the discipline we drill in the MTF questions strategy guide, and it is worth internalising long before exam day.

What Part 2 actually tests

Part 2 is the structured oral examination (SOE) — a viva conducted with examiners across several structured sections of guided clinical questions. You have already proven you know the material by passing Part 1; now you have to demonstrate that you can deploy it.

The skills Part 2 rewards are different in kind:

• Structured reasoning out loud — talking through a differential or a management plan in a logical, prioritised order.
• Clinical judgement — choosing safely between options and justifying the choice.
• Composure under questioning — staying organised when an examiner probes, redirects, or escalates a scenario.
• Communication — the way you say it matters, not only the content.

Part 2 is generally conducted in English, which is one reason international graduates sometimes feel the step up more sharply here than in Part 1. This is the edaic written vs oral exam contrast in its purest form: in the written exam your knowledge speaks for itself on paper; in the oral exam you have to speak for it, fluently, under time pressure.

For the structure of the viva — how the sections are organised and what the examiners are listening for — see the Part 2 format and SOE structure guide. When you are ready to build a revision timetable specifically for the oral, the how to prepare for Part 2 study plan is the place to start.

How each part is marked

Both parts are marked against a criterion-referenced standard rather than a curve. This matters more than most candidates realise.

In a norm-referenced exam, you are competing against the cohort — only the top slice passes, regardless of absolute performance. The EDAIC does not work that way. Standard setting is Angoff-style: the pass mark reflects a defined standard of competence — the level a safe, capable anaesthetist should reach — not a fixed quota and not a relative ranking. In plain terms: you are not trying to beat the person next to you. You are trying to clear a defined bar. If everyone in the room is competent, everyone in the room can pass.

The marking mechanism differs by part:

• Part 1 is machine-marked from your true/false responses, with no negative marking, against the criterion-referenced pass mark.
• Part 2 is scored by examiners across the structured sections, again against a defined standard of competence.

For a deeper treatment of how the bar is set and what the published figures do and do not mean, see EDAIC pass rate and pass mark explained. Avoid fixating on any single quoted percentage — pass rates move between cycles, and the official site is the only reliable source for current numbers.

A note on OLA — the route that can skip the written exam

There is a third element worth knowing about that sits alongside Part 1: the OLA (On-Line Assessment). OLA is a formative, in-training online assessment that uses EDAIC Part 1-style content. It is designed to be taken during training as a way of benchmarking your progress.

Crucially, passing OLA under ESAIC's conditions can exempt you from sitting the Part 1 written exam — effectively letting eligible candidates progress towards Part 2 without the written sitting. The eligibility rules and conditions are specific, so check them directly; our OLA online assessment explained article covers how it fits into the pathway. Even if you intend to use OLA, the knowledge it tests is the same Part 1 knowledge described above, so none of your basic-science revision is wasted.

Is EDAIC Part 2 harder than Part 1?

This is the question everyone asks, so let's address is edaic part 2 harder than part 1 honestly — the truthful answer is it depends on the candidate, but there are clear patterns.

Why many find Part 1 the bigger grind. Part 1 demands enormous breadth. You are accountable for the entire basic-science and clinical syllabus at once, and the MTF format is unforgiving of vague, "roughly right" knowledge — a statement is true or it is false. The sheer volume of detail, and the months of recall maintenance it requires, make Part 1 a marathon. Spaced repetition is close to essential here; see our spaced repetition memory method for the technique that keeps that volume retrievable.

Why many find Part 2 the bigger psychological hurdle. Part 2 introduces pressures that a written paper never could:

• It is interactive and live — there is no quiet desk to think at; an examiner is waiting.
• It is generally in English, which raises the bar for non-native speakers regardless of clinical strength.
• It demands performance, not just knowledge — you can know the answer and still under-deliver if your reasoning is disorganised or you freeze.
• It rewards verbal fluency and structure that the written exam never tested.

So the honest synthesis: Part 1 is usually harder as a test of endurance and breadth of recall; Part 2 is usually harder as a test of nerve, communication and applied judgement. Strong memorisers who dislike being put on the spot often find Part 2 the steeper climb; confident clinical communicators who struggle with high-volume rote learning often find Part 1 the worse of the two. Neither part is a formality — but neither is insurmountable with the right preparation. For a broader, reassuring overview of the whole experience, is EDAIC difficult — what to expect is worth a read.

How much prep time does each part need?

There is no single correct figure, and you should be wary of anyone who quotes one as gospel — it depends on your starting knowledge, your training stage, and how much protected study time you can carve out. But the shape of the preparation differs in instructive ways.

• Part 1 rewards a long, steady build: months of broad reading, question-bank practice, and active recall to cover and retain the full syllabus. The work is front-loaded with content acquisition and back-loaded with consolidation and timed practice.
• Part 2 rewards a shorter, sharper, more performance-oriented block: rehearsing out loud, practising structured answers, and doing mock vivas with colleagues so the format stops feeling alien. Much of your knowledge already exists from Part 1; the task is converting it into fluent spoken reasoning.

A structured timetable helps enormously for either part. Our effective study plan for EDAIC gives you a framework you can adapt to whichever stage you are at, and a dedicated Part 1 study plan and schedule breaks the written-exam build into weekly blocks.

Where the EDAIC sits relative to the FRCA

A common point of confusion for trainees comparing pathways: how does the EDAIC relate to the UK's FRCA?

The FRCA — Fellowship of the Royal College of Anaesthetists — is the UK examination, sat as the Primary FRCA and the Final FRCA, and awarded by the Royal College of Anaesthetists. The EDAIC is the broadly comparable pan-European diploma awarded by ESAIC. They are separate qualifications with different awarding bodies, each with its own structure, though both assess a similar core of anaesthetic knowledge and practice. If you are deciding between them, or hold one and are considering the other, our EDAIC vs FRCA — which anaesthesia diploma comparison lays out the trade-offs in full. Note also that exemption arrangements can exist between certain examinations — the Primary FRCA exemption rules article covers what currently applies.

Putting it together: a sensible sequence

For most candidates the journey looks like this:

1. Confirm eligibility and the current cycle dates on the official ESAIC/EDAIC (myESAIC) website. The 2026 Part 1 written exam falls on 19 September 2026, but the registration window for that sitting has already closed — so for the next cycle's dates and the live registration deadline, go straight to the official site rather than relying on any third-party figure.
2. Build broad knowledge for Part 1 — Paper A basic sciences and Paper B clinical anaesthesia — using active recall and a question bank.
3. Sit Part 1 (or, if eligible, use the OLA route) and clear the criterion-referenced bar.
4. Pivot to performance for Part 2 — practise spoken, structured reasoning and rehearse mock vivas in English.
5. Sit Part 2 and earn the diploma.

That sequencing is the practical expression of the edaic part 1 vs part 2 difference: you accumulate knowledge first, then learn to perform with it. Get the order and the emphasis right, and each stage prepares you for the next.

Frequently asked questions

Do I have to pass Part 1 before I can sit Part 2?

Yes. The EDAIC is sequential: Part 1 (the written exam) comes first, and a Part 1 pass is the prerequisite for attempting Part 2 (the oral SOE). Eligible candidates may, under ESAIC's conditions, use a passed OLA (On-Line Assessment) to be exempted from the Part 1 written exam — but you cannot start with Part 2.

Is there negative marking in EDAIC Part 1?

No. Negative marking was removed in 2014. In the MTF format, each true/false statement is scored independently: a correct answer scores, and a wrong or blank answer scores zero, with no penalty. Because of this, you should answer every single statement and never leave one blank.

Is EDAIC Part 2 harder than Part 1?

It depends on your strengths. Part 1 is usually harder as a test of breadth and sustained recall across the whole syllabus. Part 2 is often the bigger psychological challenge because it is a live oral exam, generally conducted in English, that tests applied reasoning and communication under pressure rather than pure knowledge.

What language is each part in?

The Part 1 written exam is offered in several European languages, while Part 2 is generally conducted in English. International candidates who are comfortable in their own language for the written papers should plan deliberately for spoken English fluency before the oral.

How is the pass mark decided — is it a fixed quota?

No. Standard setting is criterion-referenced (Angoff-style). The pass mark reflects a defined standard of competence, not a fixed quota and not a norm-referenced curve, so you are measured against a fixed standard rather than competing against other candidates. Confirm current pass-mark information on the official ESAIC/EDAIC website.
