PLAB 2 Marking Criteria Explained: What Examiners Actually Look For

Most PLAB 2 candidates know the exam has a mark scheme. Far fewer understand what examiners are actually doing with it while you are mid-consultation. This post breaks down the marking framework in detail — what each domain tests, how marks are awarded, and the behaviours that separate candidates who pass from those who have to return.

The Three Domains

Every PLAB 2 station is marked across three domains:

Plus a Global Score of 1 additional mark — the examiner's overall impression.

Total: 7 marks per station, across 18 stations.

You do not need to pass every station. You need to reach the overall pass mark across all 18. But consistently losing the global score — even by half a mark per station — is enough to fail the whole exam.

Domain 1: Data Gathering

This domain rewards candidates who gather information in a way that is focussed, systematic, and patient-led.

What examiners are looking for

• A clear opening that puts the patient at ease and establishes the presenting complaint
• Logical progression from open questions to targeted closed questions
• Coverage of relevant history components — SOCRATES for pain, systems review where indicated, relevant past medical history, medications, allergies, social and family history
• Active listening — following up on cues the patient gives rather than running through a checklist robotically
• Relevant physical examination: either performed or offered and described

Common reasons marks are lost

• Missing key red-flag questions (weight loss, night sweats, haematuria — depending on the presentation)
• Jumping straight to closed questions without letting the patient speak first
• Ignoring cues — the patient says "I've been really worried about it" and the candidate moves straight to the next checklist item
• Skipping social history in stations where it directly affects management (a patient's home situation matters enormously in elderly care, safeguarding, or alcohol-related presentations)

Examiner perspective: A candidate who takes a slightly less complete history but clearly listens and responds to the patient will often score higher than one who covers every item robotically but misses the cues.

Domain 2: Clinical Management

This domain tests whether you can translate what you gathered into safe, appropriate action.

What examiners are looking for

• A reasonable differential diagnosis stated clearly
• Relevant investigations proposed (blood tests, imaging, referrals — appropriate to the level of a foundation doctor)
• A sensible management plan: immediate steps, medium-term follow-up, onward referral if indicated
• Safety-netting: clear advice to the patient about when to return or call 999
• Awareness of your scope — knowing when to refer rather than manage alone

What "foundation doctor level" means in practice

A common anxiety is that candidates do not know enough clinical medicine to pass. This is rarely the problem. The exam is pegged at the level of a UK Foundation Year 1 (FY1) doctor. You are not expected to know the third-line treatment for a rare autoimmune condition. You are expected to:

• Recognise red flags and act on them
• Know when a patient needs emergency admission vs GP follow-up vs routine outpatient referral
• Give the patient clear, accurate information about their condition

Missing a sophisticated diagnosis is forgivable. Missing a safety net — failing to tell a patient with chest pain to call 999 if it worsens — is not.

Common reasons marks are lost

• Proposing investigations without explaining them to the patient
• Forgetting safety-netting entirely (extremely common under time pressure)
• Suggesting management beyond FY1 scope without acknowledging the need to discuss with a senior
• Not addressing the patient's concerns within the management plan

Domain 3: Interpersonal Skills

This is the domain most candidates underestimate and the one that most often determines the result.

What examiners are looking for

• Language: plain English, no unexplained medical jargon
• ICE: Ideas, Concerns, and Expectations elicited — ideally early, not as a box-tick at the end
• Empathy: acknowledgement of the patient's emotional state, not just their symptoms
• Checking understanding: confirming the patient has understood what you have told them
• Non-verbal communication: eye contact, body language, pace — these are observed even in a time-pressured station

ICE in practice

The Calgary–Cambridge model underpins the PLAB 2 mark scheme. Of its components, ICE is the most consistently tested and the most consistently missed.

Candidates who address ICE only at the end of the consultation — as an afterthought after completing the clinical content — frequently lose marks. Examiners look for ICE to be woven naturally into the consultation, not bolted on.

A practical approach:

• Ideas: "What do you think might be going on?" — ask this early, in the data-gathering phase
• Concerns: "Is there anything in particular you're worried about?" — this often changes the direction of the whole consultation
• Expectations: "What were you hoping we might be able to do for you today?" — particularly important in management-heavy stations

Once you know the patient's concerns, you must address them explicitly. Eliciting ICE and then ignoring it is worse than not asking at all — the role-player is trained to reflect unresolved concerns, and the examiner will note it.

Common reasons marks are lost

• Using jargon: "we'll do an FBC, LFTs, and refer to gastro" without explanation
• Acknowledging distress verbally but continuing to talk over the patient
• Asking ICE as a checklist at minute 7 rather than as a natural part of the consultation
• Not checking understanding before closing — "Does that all make sense?"

The Global Score

The global score is 1 mark awarded at the end of the station. It is the examiner's holistic answer to: "Would I be comfortable with this doctor seeing my patient?"

It is not a bonus mark for excellent candidates. It is a mark every candidate is expected to earn, and losing it consistently is one of the primary reasons borderline candidates fail.

What drives the global score

• Did the consultation feel like a real interaction with a doctor, or a performance of one?
• Was the candidate present with the patient, or were they visibly working through a mental checklist?
• Was the closure natural — or did the candidate run out of time and end abruptly?

Candidates who lose the global score usually do so for one of three reasons:

1. Robotic delivery — technically correct but no warmth or genuine engagement
2. Poor time management — running out of time and abandoning closure entirely
3. Unresolved patient concern — the patient is clearly still worried when the bell goes

A consultation where the patient leaves feeling heard scores higher than one where the candidate recited every correct clinical point but made the patient feel like a case study.

How Marks Add Up: A Worked Example

Take a history-taking station for a patient presenting with weight loss and fatigue:

Both candidates saw the same patient. Both took a reasonable history. The difference is entirely in how they did it.

Practical Takeaways

1. Treat ICE as clinical data, not a communication exercise. The patient's concerns often contain the diagnosis. A patient who says "I'm worried it might be cancer" in the second minute is giving you a gift — take it.

2. Build a timer habit. At minute 4, you should be moving into management. At minute 7, you should be closing. Practice until this is instinctive.

3. Safety-netting is not optional. In every station, at some point before the bell, you need to tell the patient what to do if things change. "If you develop any chest pain or difficulty breathing, please call 999 immediately" takes ten seconds and is worth marks.

4. Practise out loud. Reading about consultation skills does not build them. The only way to internalise ICE, smooth transitions, and natural closure is to do it — with a partner, an actor, or an AI patient — repeatedly, under timed conditions.

5. The role-player reflects what you give. A warm, engaged candidate gets a warmer patient. A rushed, clinical candidate gets a patient who becomes more distressed and harder to manage. The station dynamic is partly in your control.

The PLAB 2 mark scheme is not opaque or unfair — it rewards exactly the behaviours that make a good doctor. Candidates who pass do so because they have practised those behaviours until they are automatic, not because they have memorised clinical algorithms.

Practise the consultation, not just the content.
