MMI Station Types: What UK Medical Schools Actually Publish

Most guides on MMI station types describe the same six archetypes and cite nothing. The Medical Schools Council publishes eight categories, a 1–5 mark scheme, and a range of 7–10 stations at 3–10 minutes each. Below, those national figures sit beside the circuits UK medical schools publish themselves — station counts, clocks, assessors and scoring rules — each one taken from the school's own guidance and dated.

How many stations does a UK MMI actually have?

There is one national figure worth quoting on this question, and it does not come from an admissions blog. The Medical Schools Council's free mock-MMI pack states that multiple mini interviews "normally consist of 7–10 different interview stations, each one lasting 3–10 minutes, which an applicant rotates through in a timed circuit". That is the range this page uses throughout. An earlier version of this page said six to twelve stations of five to ten minutes each, and then contradicted itself lower down. Both figures were our own estimate presented as fact, and both have gone.

The same pack reports that of nearly 40 UK medical schools with an undergraduate medicine course, about 75% use MMIs. State the vintage when you use that number, because the pack does: the figure sits under a chart dated 2019–20. It tells you the format is the norm rather than the exception. It does not tell you which schools are running one this cycle, and the school list attached to it has aged badly — two of the schools on it have since dropped the circuit altogether.

Inside that 7–10 range, real circuits vary far more than a generic guide admits. Manchester and Plymouth each publish a five-station circuit. Bristol runs six stations and Nottingham six scenarios. Queen's University Belfast runs twelve for home applicants in person, and seven online for international applicants. The University of Lancashire says only that there are "usually between six to ten". If you are running interview practice alongside admissions test preparation, treat the station count as a per-school fact to look up rather than a number to assume, because assuming it is how candidates arrive rehearsed for the wrong circuit.

What are the eight MMI station categories?

Every competing guide on this term invents its own list of archetypes, usually five, six or seven of them, and none of them says where the list came from. There is a published taxonomy, and it has eight categories. The Medical Schools Council sets them out in its mock-MMI pack with the instruction that "each mock MMI session should contain one station from each category", and the pack ships printable station briefs, mark sheets and session timetables for all eight. It is free, it is downloadable, and no other page ranking for this term links to it.

Two things follow from that list. First, a taxonomy is not a promise: no single school runs all eight categories, and at least one publishes that it runs none of the data-interpretation kind at all. Second, these eight are what the Council recommends for practice circuits, so a mock day built around them rehearses the same spread the national body itself models for schools. That is a firmer foundation than a list assembled from forum posts, and it is the spread we use when we build circuits for candidates.

How is an MMI station actually scored?

This page used to carry a ten-row rubric running from Exceptional at the top down to Unacceptable at the bottom, described as the scale assessors are trained to apply. No UK medical school and no national body publishes such a scale. We could not source it, so it has been deleted — from the prose, from the call-to-action box that referred to it, and from the structured data underneath the page. What follows replaces it, and unlike the old table it exists in a document you can download and read yourself.

The Medical Schools Council's published mark sheet uses a global judgement out of five. Its instruction to assessors is plain: "A score out of 5 should be given for a student's overall performance." That sits alongside a station-specific checklist and space for written feedback, so the number is a summary of the station rather than the whole assessment. Five named levels carry the judgement.

The level worth studying is 3. The discriminator between an adequate station and a good one is not knowledge, and it is not polish. It is how much the interviewer had to pull you along. That one criterion is more useful than any bank of model answers, because it tells you exactly what to rehearse: reaching the substance of a station without being asked twice. Candidates who lose marks here are rarely wrong about anything. They simply wait to be invited to the point they were always going to make.

Schools then layer their own rules on top of a scale like that. Plymouth scores stations "using both a numerical scale and a red flag section", and the red flag "can only be marked Yes or No and reflects whether the applicant said something or behaved in a way that is unsuitable for the programme". Both are referred to when the outcome is decided. A red flag is not a low score with a different name; it is a separate binary field, and it survives a strong numerical performance in the same station.

What do UK medical schools publish about their own circuits?

Not one competing page on this search result carries a single row of the table below. Every figure in it comes from the school's own candidate guidance or admissions page, retrieved on 23 August 2026, and where a school publishes a range rather than a fixed number the range is what appears. Where a school does not publish something, the cell says so instead of guessing. That is the whole difference between a sourced table and the emphasis grid this page used to carry, which rated schools Strong, Moderate or Light on each station type with no source at all and was wrong on four rows.

Read down the assessors column and two different philosophies appear. Manchester puts a different interviewer at every one of its five stations and keeps the marks apart: the interviewer scores you on an iPad at the end of the station, and no interviewer sees any other station's score. Bristol goes the other way, putting three assessors on each of six stations and combining their scores, so a candidate is seen by six assessors in total in roughly thirty minutes. Aberdeen sits two selectors at each station, explores one domain for five minutes, and scores communication and interpersonal skills at every station on top of the domain itself.

Aberdeen also does something unusual that should change how you prepare: it publishes the domains in advance. Its MBChB candidates are told they will be questioned on motivation to study medicine, core qualities, critical thinking and problem solving, team work, and professionalism, and that no reading is required during the interview at all. When a school hands you the domain list, question-spotting is wasted effort. The honest task is having a specific personal example ready for each named domain. Sixth-formers preparing with us for sixth form and university entry build that grid first and script nothing, because a scripted answer is exactly what a five-minute domain probe is designed to expose.

Role-play stations: how many will you actually face?

Generic advice says be empathetic. Countable facts are more useful. Queen's University Belfast publishes that its home circuit has 12 stations, of which 9 are question stations and 3 are rest stations, and that "4 stations will have roleplayers. The interviewer will be watching your interaction with the roleplayer and marking the station as usual." Four of the nine live stations, then, are role plays. At that school role play is not a station type you might meet. It is close to half of everything you are marked on.

The proportion changes with the format and the school. The Queen's Belfast online circuit for international applicants has 7 stations, two of which include role players. Nottingham's six scenarios "will include at least one role play" across an interview lasting up to one hour. Birmingham describes its circuit as a mix of interviews, role-play and calculation tasks drawn from seven named types, with the precise combination changing day by day. So the same candidate could face four role plays at one school and one at another, in the same application cycle, with no way to tell from a generic guide.

The Queen's wording also settles a question candidates ask constantly: who are you talking to? The interviewer watches and marks; the roleplayer is the person you speak to. Playing to the assessor rather than the actor is the most common way a strong candidate loses marks in a station they otherwise handled well. Practising four role plays back to back, which is what that circuit demands, also builds the skill nobody rehearses — resetting between stations, so that a difficult conversation at station four does not follow you into station five.

Data and calculation stations: the part most guides get wrong

Every competing page on this term tells you to prepare for a data station. At least one major medical school publishes that it does not run one. Queen's University Belfast's own candidate FAQ states: "There are no stations where you are required to interpret data or graphs." It also says no station asks you to write anything down. An earlier version of this page rated Queen's Belfast as Light on data interpretation. Light implies some. The published answer is none, and that correction matters more than any tip, because it is hours of the wrong preparation.

Where a calculation station does exist, the published specification is reassuring rather than frightening. Birmingham runs a computer-based calculation station and states that "the mathematical skills that are being tested are at or below GCSE level, and those taking A level Mathematics are not necessarily at an advantage". Read that carefully. It is not saying the station is easy. It is saying the difficulty does not live in the arithmetic. Candidates who have finished GCSE maths already have every technique required, and candidates taking A-level Maths get no head start from the syllabus they are sitting.

Birmingham also names the seven station types its circuit is drawn from: critical thinking; commitment and insight into medicine; dealing with personal and ethical challenges; professionalism; data interpretation and debate; interaction in a healthcare setting, which is the role-play station; and the computer-based calculation station. Seven named types into a circuit of six or seven 8-minute stations, each including 2 minutes of preparation, is the reason the school warns that "the precise combination and scenarios being used will change on a day-by-day basis". Two candidates at the same school on consecutive days do not sit the same circuit, which is also why comparing notes with last year's applicant tells you less than reading the specification.

Why a group station can outweigh an interview station

Teamwork stations are usually described as a minor extra. Hull York Medical School publishes the point value of each component of its selection day, and the published weighting says the opposite.

The group exercise is worth more than any single interview station, and by a clear margin. A candidate who treats it as a warm-up is discarding the highest-value component of the day. Nothing in that table says the group task is harder than the interviews; it says the school has decided it carries more weight, which is a different claim and a more actionable one. It also tells you how to divide practice time when the same amount of preparation could go to either.

The scenario station at the same school shows how far a station can drift from a conversation. Candidates are shown "a pre-recorded video simulating a character talking directly to you" and asked to respond at two points during the video and once at the end. There is no interviewer to read, no back-and-forth, and no chance to recover through rapport. Dundee, which no longer runs a circuit at all, assesses its group discussion on the ability to communicate effectively, to work within a group setting, on personal values and on professionalism. Between them these two schools describe the range a modern "station" can cover: a video with fixed response points at one end, an observed discussion with five other applicants at the other.

Two schools have left the MMI circuit behind

Every school list on this search result, including the one this page used to carry, still lists Keele and Dundee as MMI schools. Both have moved on, and both say so on their own pages. Keele's interview guidance states: "Interviews for 2026 entry will be conducted online via Microsoft Teams. Each candidate will have two 15-minute interviews, each with two interviewers. Therefore, each candidate will be interviewed by four different people." That is not a circuit with a short clock and a rotation. It is two longer conversations, scored by four people who each see half of you.

Keele also publishes what those two interviews are scored against, and it is a domain list rather than a station list: preparation and resilience; ethical reasoning; professionalism; personal responsibilities; reasoning from a clinical scenario; and empathy and caring. It adds a rule worth reading twice before an online interview: "The use of generative artificial intelligence (AI) systems during your interview is strictly forbidden, and will result in rejection." Not a warning, not a deduction. Rejection.

Dundee, the school most often credited with bringing the multi-station format to UK medicine, has gone further from the circuit than anyone. Its published description is that "the interview consists of two main parts. An observed preparatory group discussion, followed by a structured interaction with an assessor." The group discussion runs with five other applicants for around thirty minutes, and the whole event takes one hour and forty minutes. A candidate who spends a month rehearsing five-minute stations for Dundee has prepared for an interview that school stopped running.

Swansea is a third case, and a gentler one. Its Graduate Entry Medicine interview page describes five key competencies and a presentation the applicant delivers, not a station circuit — yet the old version of this page rated it Strong on role play and teamwork. The lesson is not that any of these schools did anything unusual. It is that a school list on this topic goes stale within one admissions cycle, and the only reliable version is the one on the school's own site for the cycle you are applying in. Check it in the month you apply, not the year.

The published rules that actually decide the offer

Almost every guide tells you stations are scored independently so a bad station will not sink you. For at least one school, the published rule says the opposite. Birmingham writes: "It is likely that we will set a minimum performance standard for each station, except for calculation stations. This standard will be well below the average score, so any applicant who does not reach the minimum standard for one or more stations may not receive an offer, irrespective of their overall interview score." A single station below the floor can cost the place, however strong the total.

Birmingham also folds the UCAT situational judgement test into the circuit arithmetic. The maximum score for each MMI station and for the SJT component is the same, so all stations and the SJT are equally weighted, and the bands convert directly: Band 1 scores the maximum, Band 2 two thirds, Band 3 one third, Band 4 zero. In effect the SJT is an extra station you sat months earlier and cannot re-take on the day, which is a good reason to treat the SJT as interview preparation rather than as a test-day afterthought.

Other schools publish their own decision rules, and they are not the same rules. Plymouth carries the numerical score and the binary red flag together into the outcome. Manchester keeps station scores completely independent, because no interviewer sees another station's mark. Nottingham makes offers on interview performance alone. The University of Lancashire makes offers in rank order of MMI score. Four schools, four different ways a strong day converts into an offer, and no generic statement about independent scoring covers all four.

The practical consequence is a change in how you allocate practice. Under a rank-order rule, raising every station a little is the efficient move. Under a per-station minimum, your weakest station type is the only thing that matters until it clears the floor. Under a red-flag rule, one careless sentence about a patient or a colleague is worth more attention than any amount of polish. The rule you are being judged under is published; it takes about ten minutes per school to find it.

In person or online: same station types, different clock

The format you sit changes the numbers more than it changes the station types, and international applicants get the sharper end of it. Hull York Medical School gives in-person candidates five minutes of thinking time before each station, having handed them the first question, while overseas candidates interviewing online get two. The station is the same. The preparation window is less than half as long, which means a plan that depends on drafting an answer in your head simply will not fit.

The same school attaches a hard penalty to an administrative step: applicants who do not attend the pre-briefing receive a "-20 point penalty against their interview score". Set against a scoring sheet whose largest single component is worth 22 points, missing a webinar costs almost as much as failing the group exercise outright. It is the cheapest twenty points on the entire selection day, and it is lost by candidates who assume a briefing invitation is optional.

Circuit length shifts too. Queen's Belfast runs 12 stations in person for home applicants and 7 online for international applicants, two of them with role players. Rehearsing for twelve when you will sit seven, or the reverse, misjudges the stamina the day requires and the number of fresh starts you will need. Confirm which circuit you have been invited to before you decide how to practise, then practise at that length end to end, with the same clock and the same gap between stations.

How many applicants ever reach a station?

This page used to carry a block of international-applicant statistics — a percentage cap, a national places total, an applicant count, a named school's ratio, an English language threshold. None of them could be traced to a primary source in this review, and at least one of them describes a policy that has changed. They have been removed rather than left standing with a hedge, because an unsourced number on a page like this is worse than no number at all.

One school does publish its whole funnel, and it is more informative than any ratio those figures offered. King's College London states that applications for its undergraduate medical programmes run at around 5,500 a year for roughly 410 places, that around 4,000 of those are for A100, that 1,200 to 1,400 applicants are selected for interview across all medicine programmes, and that there are around 300 places on A100. Interview day is already a shortlist of roughly a quarter of applicants, and the offer rate among those interviewed is far kinder than the headline number suggests.

King's is also a caution about sources. A July 2023 FAQ from the school describes an MMI of seven stations, each run by a different member of staff asking one question each. The current course page describes the interview without naming a station format. Both documents are the school's own. Only one is current, and the older one is the one that turns up in search results and gets quoted on advice sites. When a school stops publishing its format, the honest thing to write is that it has stopped publishing its format.

Where the questions come from, and the values underneath them

Candidates often notice that stations at different schools feel oddly similar. There is a documented reason, and no competing page on this term mentions it. The Medical Schools Council Selection Alliance runs item-writing events and maintains a shared national bank: "Medical schools have access to the online MMI bank and can use items in their own MMI circuits." The items are written with input from several medical schools, patients and students, and reviewed before they enter the bank. Circuits are not written from scratch by each admissions team every autumn.

That reframes question-bank preparation honestly. It does not mean the questions leak, and it does not mean a commercial bank of scenarios contains the real items. It means the underlying construct is shared, so practising the category is rational while hunting the exact question is not. It also explains why a station at one school can feel like a station a friend described at another.

Underneath the item bank sits the framework that answers the question candidates most want answered: what are assessors actually looking for? The Medical Schools Council statement on the core values and attributes needed to study medicine is, in its own words, "mapped to the General Medical Council's Good Medical Practice, the overarching ethical guidance for doctors in the UK", and it also draws on the values in the NHS Constitution. Schools then align to it visibly: Plymouth aligns its eight assessed qualities to the NHS core values, and Nottingham bases its interview qualities on the Council's guidelines.

So the honest answer to what a station is testing is not a trick and not a secret. It is a published values framework, delivered through a shared item bank, marked on a five-point global judgement, with school-specific decision rules on top. Everything in that sentence is downloadable. Candidates who read the four documents behind it are better prepared than candidates who have memorised a hundred model answers, and it is the reading we set first for anyone working with our subject specialists on a medicine application.
