MRCPsych CASC Prep: Station Practice Roadmap

Good MRCPsych CASC prep is not about doing random stations until you feel wrung out. Build your practice around the current blueprint: the CASC is an in-person, 16-station exam completed in two circuits on the same day, with 5 history stations, 5 examination stations and 6 management stations, and every station also tests communication.

That matters because you do not pass by producing a few heroic stations. RCPsych says you must meet the overall borderline regression standard and pass at least 12 stations, and the pass-level standard is framed around competence expected of a newly appointed ST4.

Why this matters

Examiners are listening for a consultation that is systematic, safe, patient-centred and responsive, not a memorised script. The official criteria emphasise consultation management, clinical assessment and management including risk, and effective communication; role players are trained to respond to how you behave, so brusque or robotic communication can make the station harder, not easier.

Your roadmap therefore needs three things: blueprint coverage, timed repetition, and brutally honest feedback.

Build your MRCPsych CASC prep around the blueprint

Start with a tracking grid rather than a long revision list. The current CASC syllabus is mapped to the 2022 Core Psychiatry Curriculum and has applied from September 2023, and each running order includes explicit coverage across history, examination, management and communication. There will always be at least one risk or safety station, one cognitive or capacity station, and one physical health history or physical examination station.

You also do not need to design revision around old linked stations. RCPsych says linked stations are no longer part of the exam.

Track every practice station against:

station type: history, examination, or management
specialty area: child and adolescent, general psychiatry, psychiatry of intellectual disability, old age, forensic, medical psychotherapy, or addiction
theme: risk or safety, cognitive or capacity, physical health, formulation, legal or ethical issues
communication emphasis: personalisation and respect, response to cues, empathy, or clear explanation.

This is the easiest way to spot blind spots. Many candidates over-practise acute psychosis histories and under-practise collateral histories, capacity, cognitive assessment, formulation, and explanation stations. RCPsych also states that physical health can be tested in any station type, so every case should trigger a quick physical-health check in your head.

A repeatable station practice roadmap

Run a two-week cycle

A practical cycle works better than a vague promise to do more stations. Repeat the block below until the exam, changing diagnoses, ages, and specialty settings each time.

Week 1 should be weighted towards information gathering:

2 history stations: one acute adult case and one collateral, developmental, or social history case
2 examination stations: one MSE-focused case and one cognitive, capacity, or risk-focused case
1 mixed mini-circuit of 4 stations under timing
1 debrief session where you log misses by domain, not by diagnosis.

Week 2 should be weighted towards management and explanation:

2 management stations: one formulation or explanation task and one biological, psychological, or holistic management plan
1 legal or ethical station built around principles of involuntary treatment, capacity, safeguarding, or confidentiality
1 mixed mini-circuit of 4 stations under timing
1 repair session where you immediately rerun the stations you handled badly.

If you have longer than six weeks, keep repeating this cycle. If you have less time, do fewer stations but keep the mix.

Match the real timings

At least once each week, practise morning-style stations with 4 minutes of reading time and 7 minutes to perform the task, and afternoon-style stations with 90 seconds of reading time and 7 minutes to perform the task. Also practise switching gears between history, examination and management rather than batching only your favourites.

That timing matters. A candidate who is safe but slow will still struggle.

How to run a single station well

Most lost marks come from solving the wrong problem. RCPsych says candidate instructions are explicit and may also include negative instructions telling you what you are not expected to cover, so your first job is to obey the task, not to show everything you know.

In your reading time, look for five things:

the task verb: assess, explain, manage, counsel, or take a history
who you are speaking to: patient, relative, carer, or colleague
the priority domain: risk, capacity, diagnosis, formulation, or management
what must be covered before the bell
what is deliberately outside scope.

Once you enter, use a simple station spine:

open with role, purpose, and a focused agenda
gather or deliver information in a clear order
prioritise risk, function, and relevant physical health early
summarise your working understanding
close with a practical next step and safety net where relevant.

Worked example: history station

A 24-year-old is brought by his sister after saying neighbours are sending messages through the television. A strong opening would set the agenda, establish rapport, then move quickly through presenting symptoms, timeline, substance use, risk, collateral function, and immediate safety, instead of spending three minutes on a full personal history. That is closer to the official standard of being systematic, focused and responsive to the task.

Worked example: management station

A mother asks why her 15-year-old daughter who self-harmed may need urgent assessment. A good answer is brief and structured: explain the immediate concern, outline what needs assessing now, show how risk and safeguarding affect the plan, and use a biopsychosocial explanation rather than a bare label. If the station moves into legal or ethical territory, show you understand the principles around capacity, consent, and least restrictive care; the syllabus does not expect recital of jurisdiction-specific statute wording.

What examiners reward

At pass level, the exam is not asking for a flawless performance. It is asking for a clinically justifiable, reasonably systematic, technically competent interaction with appropriate communication and the essential issues covered at newly appointed ST4 standard.

In practice, that usually sounds like this:

'I want to make sure I understand what has been happening, then I'll ask a few questions about safety before we decide what help is needed.'
'From what you've told me, my immediate concerns are...'
'My working understanding is...'
'The first steps today would be...'

Those phrases work because they show structure, prioritisation and ownership. Short, clear language scores better than a polished but vague monologue.

The current syllabus also makes communication broader than just sounding kind. Personalisation and respect, responding to cues, empathy, and providing clear accurate information are all explicit communication emphases, and the syllabus expects you to work effectively with people from different cultural, social and neurodevelopmental contexts.

Common mistakes

These failure patterns map closely to the published criteria, syllabus and grade descriptors:

doing a full clerking when the task asks for a focused assessment
missing risk because you are busy showing diagnostic knowledge
treating management stations as drug-recall exercises instead of collaborative plans
forgetting physical health, medication effects, or investigations
using stock empathy lines that do not respond to what the person has actually said
failing to summarise, explain your formulation, or state the next step
sounding certain when the safer answer is to acknowledge uncertainty and explain how you would manage it
getting lost in legal detail instead of showing sound principles and patient-centred reasoning

Practice workflow

The most useful rehearsal loop is simple: timed station, immediate self-score, external feedback, rerun. RCPsych's own current CASC practice course is built around mock stations under exam conditions, observation, marking and feedback from CASC examiners, which is a sensible model for any study group.

A good group session looks like this:

one person plays candidate
one plays role player
one marks structure, timing, risk, and closure
hard stop at 7 minutes
3-minute self-debrief from the candidate first
5-minute feedback from the marker
2-minute rerun of the weakest section only

AI rehearsal can help with fluency and scenario variation, especially for repetition after work, but use it as a practice partner rather than as your authority on exam regulations or UK best practice. Keep checking RCPsych and current guidance for anything date-sensitive.

In the last two weeks, shift the balance from reading to performance. By then, you should be spending more time speaking, timing, closing stations, and repairing weak patterns than collecting more notes.

Summary

Base your MRCPsych CASC prep on the real blueprint: 16 stations, two circuits, and broad coverage across history, examination, management, communication, risk, capacity and physical health.
Practise for breadth, because the pass rule rewards consistent performance across the exam rather than a few standout stations.
Read the task carefully and obey it; overshooting the brief wastes time and often loses marks.
Aim for ST4-level performance: safe, structured, empathetic, and clinically justifiable.
Use weekly timed mocks, tough debriefs, and rapid reruns to turn knowledge into exam behaviour.
