AMC Clinical Exam Marking: The Three Layers Examiners Actually Use

AMC clinical exam marking runs on three distinct layers inside every station, and understanding the difference between them matters more than memorising any single number. A checklist of two to five key steps is marked simply observed or not observed. Separately, three to five assessed domains are each rated on a seven-point scale. Separately again, the examiner makes one global rating of your overall performance on that station, also on a seven-point scale - and it is this global rating that actually determines whether the station is a pass or a fail. Across the exam as a whole, 14 of your 16 assessed stations are scored (two are unscored pilot stations you are not told about), and you pass by achieving a pass score in 9 or more of those 14, with no averaging between them. A large share of the confusion in AMC clinical exam marking guides comes from a fourth, unrelated concept being folded into this picture: the four predominant assessment areas. Those describe what a station is testing, not how your performance in it is scored, and treating them as interchangeable with marking domains is a genuine and common error.

This article separates the three marking layers cleanly, explains how they relate to each other, and then explains the separate idea of predominant assessment areas - because getting this distinction right changes how you should actually prepare. For the wider preparation picture, see our AMC clinical exam pillar guide and the detailed walkthrough of the exam format.

The three layers of AMC clinical exam marking

Every scored station is assessed through three separate mechanisms, applied in sequence by the same examiner. They are not three versions of the same score - each captures something different, and only one of them decides the station's outcome.

Layer 1: Key steps (observed / not observed)

Each station has, typically, between two and five key steps: specific, concrete actions the candidate is expected to demonstrate, such as a particular question, examination manoeuvre, or safety check relevant to that scenario. Each key step is marked in binary fashion - observed, or not observed. There is no partial credit and no seven-point grading at this layer; it is a simple record of whether you did the thing.

Layer 2: Assessed domains (seven-point scale, no pass mark)

Separately, each station has, typically, between three and five assessed domains: broader aspects of performance the examiner rates individually, drawn from a standard set that can include your approach to the patient, history taking, choice and technique of examination, accuracy of examination, use of test equipment, performance and explanation of any procedure, choice and interpretation of investigations, diagnosis and differential diagnoses, management planning, and patient counselling or education. Each domain is rated on a seven-point scale. Importantly, the AMC states explicitly that there is no pass/fail point on these individual domain ratings - they are a structured record of your performance across different competency areas, not a pass/fail decision in themselves.

Layer 3: The examiner's global rating (what decides the station)

Finally, having observed the key steps and rated the assessed domains, the examiner makes one global rating of your overall ability on that station - again on a seven-point scale. This is the layer that actually determines whether the station is a pass or a fail. The AMC's Clinical Examination Specifications document (the current version is V8.3) states the cut-point in plain terms: "a score of three or below constitutes a fail score, and four or above constitutes a pass score (in the global rating only)." That arithmetic is published and current, so treat it as reliable - but it only tells you where the line sits, not what makes an examiner give you a 4 instead of a 3 on a borderline performance, which is the harder, more subjective judgement this article is really about.

Layer	What it captures	Scale used	Role in the result
Key steps	2-5 specific expected actions per station	Observed / not observed	Feeds the examiner's overall impression; not separately pass/failed
Assessed domains	3-5 broader performance criteria per station	Seven-point scale, no pass/fail point	Informs the examiner's judgement; not itself the station outcome
Global rating	Examiner's single overall judgement of the station	Seven-point scale	This is what determines pass or fail for that station

Why this is three systems, not one

Because these are three separate mechanisms rather than one aggregated score, performance on one layer does not automatically translate into a particular result on another. Ticking every key step in a station does not guarantee a pass, because the global rating captures things a checklist cannot - your overall clinical safety, organisation, communication and judgement under time pressure. Equally, missing a single key step does not automatically fail you, if your overall performance still earns a strong global rating from the examiner. This is precisely why generic checklist-memorisation is a weaker preparation strategy than practising the whole station under realistic conditions: examiners are marking your overall clinical performance, using the checklist and domains as structured inputs to that judgement, not as a simple points tally. Our common mistakes in AMC clinical stations breakdown covers this pattern in more depth, and deliberate practice against a full station timing is one of the most direct ways to close the gap between checklist completion and a strong overall rating.

The four predominant assessment areas are a different concept entirely

Separately from the three marking layers above, every AMC clinical station is built around one of four predominant assessment areas:

1. History taking
2. Examination
3. Diagnostic formulation
4. Management, counselling and education

These four categories describe the type of task the station is testing - what you are being asked to do - not how your performance is scored once you are doing it. A history-taking station and a management-and-counselling station will each still be marked using the same three-layer structure above: key steps, assessed domains, and a global rating. The predominant assessment area tells you what the station's centre of gravity is; the marking layers tell you how any station, whatever its focus, is actually scored.

Conflating these two concepts is one of the most common errors we see in online AMC preparation content - articles that describe "the four marking domains" as though they were the seven-point-scale domains discussed above. They are not the same thing, and preparing as though a station's predominant assessment area is itself a scoring category will leave you under-prepared for the domains, key steps and global rating that are actually being applied within it. Structuring revision around task type - history-taking stations, examination stations, counselling and management stations - is a sound way to build station-specific skill, but it needs to sit alongside separate practice of the marking mechanics described here, not instead of it.

How station scores add up to your result

The marking that happens inside a single station is only half the picture. The other half is how station-level outcomes combine into your overall exam result.

• The exam has 20 stations in total: 16 assessed stations and 4 unscored rest stations.
• Of the 16 assessed stations, 14 are scored and 2 are unscored pilot stations being trialled for future exams. Candidates are not told which stations are pilot.
• To pass, you must obtain a pass score in 9 or more of the 14 scored stations.
• There is no averaging across stations. A strong result on several stations cannot compensate for a failed station elsewhere - consistency across the set of 14 is what the standard requires.

That 9-of-14 figure is worth a specific note of caution. The pass mark was lowered from 10 of 14 stations to 9 of 14, effective from 21 March 2024, following a decision by the AMC's Assessment Committee and Directors. Some older reference documents, including AMC specification PDFs published before that change, still show the previous 10-of-14 figure - which is now superseded. This is a useful, general lesson about AMC clinical exam marking guides: even official-looking documents can lag behind a live policy change, so always confirm the current standard directly on the AMC's clinical examination page before you rely on a specific number, rather than trusting a cached figure from a coaching blog or an outdated PDF.

What this means practically for your preparation

Put together, the three-layer marking structure and the 9-of-14 aggregation standard have concrete implications for how you should prepare, not just what you should know.

• Treat every station as if it is scored. Since you are never told which two of the sixteen assessed stations are pilot, there is no strategic value in trying to identify them, and every reason to perform at your best throughout.
• Do not prepare as a checklist exercise. Because the global rating - not the key-step checklist - decides the station, your preparation should target the overall clinical performance an examiner is forming an impression of: safety, structure, communication, and sound reasoning, not simply "did I say the right words."
• Do not assume a single weak station is recoverable. With no averaging, a station you handle badly is not offset elsewhere; it needs to be one of the (at most) five scored stations you can afford to under-perform in and still reach 9 of 14.
• Separate your study of station task types from your study of marking mechanics. Practising history-taking stations, examination stations, and management stations (the four predominant assessment areas) is about building task-specific skill; understanding key steps, domains and the global rating is about understanding how any of those tasks gets scored once you are performing it.

Deliberate practice against realistic station conditions - full ten-minute timing, an examiner-style observer, and structured feedback across the domains above - is what closes the gap between knowing the theory of AMC clinical exam marking and performing well against it under exam pressure. This is the same domain-based structure our mock exam feedback is built around on the AMC clinical hub, so that practice sessions mirror the actual marking layers rather than a generic checklist.
