MRCEM OSCE common station fails

Facts last verified 30 May 2026.

What does the MRCEM OSCE actually test?

The MRCEM OSCE is the third and final component of MRCEM. It is a circuit of short, scenario-based stations sat at an RCEM-approved test centre. The current format is 16 stations of 8 minutes each plus 1 minute reading time per station, with two rest stations built in. There are no double stations in MRCEM. Each station maps to one or more of the RCEM Specialty Learning Outcomes (SLOs) and is marked across a defined set of domains rather than a single global score.

The point that catches people out is not the format but the marking. You are not being scored against a private checklist of facts. You are being scored on whether your behaviour in the room demonstrates the named competencies — communication, history taking, examination, practical skill, clinical reasoning, organisation, teaching — at the standard expected of a doctor at the end of core EM training. Stations that look identical on paper can mark very differently depending on which domains are weighted.

Resuscitation has its own rule. There are two resuscitation stations in the circuit and candidates are expected to pass at least one. Failing both is an automatic overall fail regardless of how strong the rest of the circuit looks. Most other fails are cumulative — death by a thousand small omissions across the day rather than one catastrophic station.

Which stations do candidates fail most often?

Examiner feedback and candidate post-mortems repeatedly cluster around the same handful of station types. The pattern is consistent across course providers and across cohorts.

• Communication and breaking bad news. Rushed delivery, no warning shot, no pause for emotion, premature reassurance.
• Paediatric history. Adult-style history taking with safeguarding, red flags and the family/social context skipped.
• Procedural skills. Missed safety steps — consent, hand wash, equipment check, post-procedure debrief — even when the procedure itself is technically correct.
• Teaching. Talking at the learner with no framework, no learning objective and no practice phase.
• Resuscitation. Acting as a clinician rather than as a team leader; instructions given but never closed.
• Ethics, consent and capacity. Asserting that the patient lacks capacity rather than actually assessing it against the legal test.
• Data interpretation and explaining to a relative. Reciting the abnormality back in medical vocabulary instead of translating it into plain English.

The rest of this article works through each of these in turn. The unifying theme is that the candidates failing these stations almost always knew the underlying medicine. They lost marks on observable, fixable behaviours.

Why do candidates fail communication and breaking bad news stations?

The recurring failure mode is pace. Candidates know the SPIKES framework (Setting, Perception, Invitation, Knowledge, Empathy, Strategy/Summary) and treat it as a script to complete inside 8 minutes. They burn through Setting and Perception in 30 seconds, deliver the news in another 30 seconds, then fill the remaining time with management plans the relative is not yet ready to hear. Examiners typically reward the candidate who slows down at the moment the news lands, allows silence, names the emotion in the room, and lets the actor decide what they want next.

The other repeat fault is false reassurance — variants of “everything will be fine”, “try not to worry”, or “the team is doing everything they can” used as filler when the candidate feels uncomfortable. It almost always costs empathy marks. The fix is small: use a warning shot (“I’m afraid I have some difficult news”), deliver one short, plain-English headline sentence, then stop talking. Whatever the actor does next becomes the next prompt — questions get answered, tears get acknowledged, anger gets validated. Plans for next steps come at the end, not the middle.

What goes wrong in paediatric history stations?

Paediatric stations punish candidates who default to an adult history template. The information you are expected to gather is broader — birth and developmental history, immunisations, feeding, growth, school or nursery, and the people who live with the child — and the safeguarding lens runs through all of it. Candidates who fail these stations typically take a competent symptom history, miss the social context entirely, and then fail to flag any of the red flags the case was designed around.

Common red flags written into MRCEM paediatric scenarios include delayed presentation, inconsistent or changing history between caregivers, an injury pattern that does not fit the developmental stage of the child, a new partner in the household, repeated attendances, and parental factors such as substance use or mental illness. You do not need to make a safeguarding diagnosis in the room. You do need to ask the questions that would reveal one, and to verbalise — to the examiner if not to the actor — that you would discuss the case with the paediatric team or the safeguarding lead before discharge.

What is the most common procedural station mistake?

Almost universally: omitting the surrounding safety steps. Candidates who have done a particular procedure hundreds of times on shift will walk into a procedural station and start doing it. They forget to introduce themselves, confirm the patient, gain consent, wash hands, check equipment integrity and expiry, position the patient, brief on what they are about to do, and debrief afterwards. The technical part of the procedure may be flawless and still produce a fail because the marking domains weight the safety wrap as heavily as the skill itself.

Treat every procedural station as if you were being filmed for a teaching video. Verbalise everything you would normally do silently. Talk through the equipment as you assemble it, name the landmarks as you find them, narrate the sharps disposal, and finish with a one-line debrief and post-procedure plan. If something goes wrong with the simulator, say what you would do in real practice — examiners are looking for safe behaviour, not a perfect run.

Why are teaching stations such a marks pit?

Teaching is the station type with the most consistently reported underperformance. The pattern is the same regardless of the clinical topic: the candidate launches into a monologue, dumps content for six minutes, asks if the learner has any questions, and runs out of time. There is no learning objective, no check for prior knowledge, no opportunity to practise, and no feedback loop. The marking domain for teaching skills is unforgiving here because the absence of structure is visible from the first 30 seconds.

Use a named framework and signal it explicitly. Common UK-recognised options include set-dialogue-closure approaches such as Set–Dialogue–Closure or BST (Briefing, Simulation/Skill, Teaching/Debrief) for practical skills, and feedback models such as Pendleton’s or SET-GO (What I Saw, What Else did you see, What do you Think, What Goals, How can we get there). Open with the learning objective. Check what the learner already knows. Teach in short chunks with comprehension checks. Hand over for practice. Close with feedback the learner contributes to first. Any reasonable framework, signposted out loud, scores better than the most technically accurate monologue.

What loses marks in resuscitation stations?

The signature mistake is acting as the most senior clinician in the room rather than as the team leader. Candidates examine the patient themselves, draw up drugs themselves, attach the monitoring themselves, and forget that the actors playing the team are there to be directed. The result is a candidate who looks busy, competent and clinically sound — and who scores poorly on leadership, organisation and communication domains because they never delegated, never closed an instruction, and never reassessed.

State the role out loud at the start: “I’m the team leader, I’d like a primary survey, IV access, bloods including a gas, and the resus trolley please.” Give task-specific instructions to named people (“airway doctor, please assess the airway and let me know”). Use closed-loop communication — the team member repeats the instruction back, performs it, and reports the result. Reassess after every intervention. Verbalise your ABCDE structure even when it feels artificial. The two resus stations are also the only place in the circuit where a single station fail can sink the whole exam, so over-investing in this skill pre-exam is rational.

How do ethics, consent and capacity stations catch people out?

The trap is conflating disagreement with incapacity. A patient who wants to self-discharge against medical advice has not, by virtue of refusing care, demonstrated lack of capacity. Candidates who fail these stations tend to assume incapacity from the outset and proceed to detain or treat the patient, rather than working through the four-part test under the Mental Capacity Act 2005 — can the patient understand the information relevant to the decision, retain it, weigh it up, and communicate their choice? All four must fail for capacity to be absent for that specific decision at that specific time.

The other repeat error is failing to make the consent conversation genuinely two-way. Reciting risks and benefits at the patient is not informed consent; checking that they have understood and inviting their questions is. For capacity assessments, demonstrate the test by asking questions that probe each of the four elements out loud, then state your conclusion and your reasoning. If capacity is borderline or fluctuating, say so and outline what you would do next (involve next of kin, IMCA, senior, document carefully).

What goes wrong in data interpretation and explain-to-a-relative stations?

The structure of these stations is unusual: you interpret something — an ECG, a CT head report, a blood gas — and then explain the finding and its implications to a non-medical actor. Candidates who are strong at the interpretation often fail the communication half because they translate poorly. They use words like “infarct”, “haemorrhage”, “acidosis” or “intubation” without checking they have landed, or they hedge so heavily the relative leaves with no idea what is going on.

Two specific fixes. First, build a one-sentence plain-English headline before you start talking, and lead with it (“the scan shows a bleed on the surface of the brain”). Then explain what that means for the patient in concrete terms (“it’s serious, and the team needs to act quickly”). Second, pause and check understanding after each chunk — not with “does that make sense?”, which invites a polite yes, but with “can I check what you’ve understood so far?” or “what questions does that bring up?” Examiners typically score this domain on whether the relative could plausibly retell what they were told.

How do candidates run out of time, and how do you avoid it?

Time mismanagement is the second-order failure mode that converts a borderline performance into a fail. Eight minutes feels long until the actor brings up something unexpected. Candidates who run out of time tend to share two habits: they do not glance at the clock, and they do not have a mental shape for each station type that tells them where they should be at the halfway mark.

Build internal pacing benchmarks during practice. A history station should have its presenting complaint, systems review and red flags done by the four-minute mark, leaving time for ICE (ideas, concerns, expectations), summary and plan. A communication station should have the news delivered by minute three, leaving five minutes for the relational and planning work. A procedural station should be set up and consented by minute two. Wear a watch you can read at a glance and use it.

How does examiner feedback differ from your own perception of the station?

One of the more disorienting features of OSCE post-mortems is how often candidates’ confidence after a station is uncorrelated with their score. Stations that felt smooth often score worse than expected because the candidate was performing fluently but missing domain-specific behaviours the examiner needed to see. Stations that felt clunky sometimes pass because the candidate, despite stumbling, hit the marked behaviours — safety steps, framework signalling, closed-loop instructions, capacity test components.

The practical implication for revision is to stop using “how it felt” as your training signal. Practise with someone using a marking grid mapped to the published domains, ask them to score the behaviours rather than your overall vibe, and pay particular attention to anything you did silently. If the examiner cannot see or hear the behaviour, it is not marked.

Station type — what examiners are scoring — common fail — the fix

How should you train differently in the last four weeks?

The last four weeks before the OSCE are not for new content. They are for converting things you already know into observable behaviours under time pressure. Three practical shifts.

• Stop revising silently. Every revision session should include at least one station verbalised out loud, ideally to another person. Reading station scenarios in your head builds false confidence.
• Get marked, not just timed. Find a study partner or course peer who will sit with a marking grid and tick the domains you hit. “How did that feel?” is worthless feedback at this stage.
• Rehearse the safety scaffolds until they are automatic. Hand wash, introduction, consent, capacity test, closed-loop, debrief, safety net. These are the cheap marks every failing candidate left on the table.

If you have access to a mock OSCE course, use it for the marking feedback and the unfamiliar stations rather than for the topics you are already strong on. If you do not, a study partner with a printed marking grid and a stopwatch gets you most of the way there.

What does the RCEM say officially about why people fail?

RCEM publishes the OSCE structure, the SLO mapping and the domain-based marking approach. It does not publish a station-by-station failure rate broken down by mistake category, and individual examiner feedback is not released. What candidates receive after a fail is a domain-level breakdown showing which competencies fell below standard, not a list of specific behaviours scored. That is why most of the granular advice in this article (and in every other article on the topic) is drawn from course examiners, mock OSCE feedback and candidate post-mortems on r/MRCEM and similar forums rather than from official RCEM documentation. Treat specific examiner expectations as patterns rather than as published criteria — they are recurring, but they are not authoritative.

FAQ

What is the most common reason candidates fail the MRCEM OSCE?

There is no single most common reason — fails are usually cumulative across stations rather than catastrophic in one. The recurring themes in candidate post-mortems are rushed communication stations, omitted safety steps in procedural stations, monologue-style teaching stations, and behaving like a clinician rather than a team leader in resuscitation. Knowledge gaps are rarely the limiting factor.

How many MRCEM OSCE stations are there and how are they marked?

The current MRCEM OSCE is 16 stations of 8 minutes each plus 1 minute reading time, with two rest stations built into the circuit. There are no double stations. Each station is marked using domain-based marking against the competencies relevant to that scenario — communication, history taking, examination, practical skills, clinical reasoning, organisation and teaching — rather than a single overall score.

Can you fail the MRCEM OSCE just on the resuscitation stations?

Yes. The MRCEM OSCE includes two resuscitation stations and candidates are expected to pass at least one. Failing both is an automatic overall fail regardless of how well the rest of the circuit goes. This is the only station type where a single bad performance can sink the whole exam, so over-investing in resus practice is rational.

Why do candidates fail communication and breaking bad news stations?

Most commonly because they rush the delivery, fill silence with false reassurance, and never pause for the actor to react. Examiners typically reward candidates who use a warning shot, give the news in one short plain-English sentence, then stop talking and let the relative drive the next move. Management plans belong at the end, not in the middle of the emotional moment.

What is the biggest mistake in MRCEM OSCE procedural stations?

Skipping the safety wrap around the procedure. Candidates who do the procedure hundreds of times on shift will often launch into the technical part and forget consent, hand wash, equipment check, sharps handling and post-procedure debrief. The marking weights the safety behaviours as heavily as the technique, so a flawless procedure with no consent or hand wash can still fail.

Which teaching framework should I use in the teaching station?

Use any recognised framework, signposted out loud. Common UK-recognised options include Set–Dialogue–Closure or BST (Briefing, Simulation/Skill, Teaching/Debrief) for the teaching itself, and Pendleton’s or SET-GO (What I Saw, What Else, What do you Think, What Goals, How can we get there) for feedback. A clear objective at the start, a practice phase in the middle and learner-led feedback at the end matter more than which specific model you pick.

How do I lead the resuscitation station properly?

State the role explicitly at the start (“I’m the team leader”), delegate tasks to named team members, require closed-loop communication (the team member repeats the instruction, performs it, and reports the result), and reassess after every intervention. Avoid doing the work yourself — the actors are there to be directed. Verbalise your ABCDE structure even when it feels artificial.

How do you fail an MRCEM capacity assessment station?

By assuming a patient who disagrees with the medical plan lacks capacity. Disagreement is not incapacity. You need to work through the four-part Mental Capacity Act 2005 test out loud — can the patient understand, retain, weigh and communicate the decision — and only conclude lack of capacity if one or more elements fail for that specific decision at that specific time. Document and escalate appropriately.

How do I avoid using jargon in explain-to-a-relative stations?

Before you start talking, build a one-sentence plain-English headline of the finding and lead with it. Translate medical terms into concrete consequences (“a bleed on the surface of the brain” rather than “a subarachnoid haemorrhage”). Pause after each chunk and ask the relative to summarise what they have understood rather than asking “does that make sense?”, which usually gets a polite yes regardless.

What do paediatric MRCEM OSCE stations expect that adult ones do not?

A wider history (birth, development, immunisations, feeding, growth, school, household), an explicit safeguarding lens, and recognition of paediatric red flags such as delayed presentation, inconsistent history, injuries inconsistent with developmental stage, a new partner in the household, repeated attendances, or parental risk factors. You do not need to make a safeguarding diagnosis in the room — you do need to ask the questions and verbalise that you would escalate appropriately.

How much does the MRCEM OSCE pass mark vary between sittings?

The numerical pass standard is set per sitting using a published RCEM methodology rather than being a fixed percentage. What matters for revision is the pattern: candidates do not fail by being one mark short on most stations — they fail by being well below standard on a handful of stations and average on the rest. Targeting the recurring weak station types is higher-yield than trying to nudge every station up by a few marks.

Where can I find official RCEM guidance on why candidates fail?

RCEM publishes the OSCE structure, the SLO mapping and the domain-based marking approach on rcem.ac.uk, and provides post-fail candidates with a domain-level breakdown. It does not publish specific examiner expectations or per-station failure rates. Most granular advice on why candidates fail — including this article — is drawn from course examiners and candidate post-mortems rather than published RCEM criteria, and should be treated as patterns rather than as official scoring rules.
