# How the ECOE works and how it is marked

- OSCE station

The ECOE is a practical exam: students rotate through timed rooms, each with one clinical task, and an examiner marks what they actually do and say.

Updated Nov 13, 2026

## Key points

- Read the task on the door carefully and do exactly what it asks: a history station is not marked for examination or treatment.
- Checklists reward observable actions, so say what you check and why; silent thinking earns no marks.
- Global ratings capture fluency, empathy and organisation, which a checklist alone misses.
- The standardised patient plays the case the same way for everyone and often gives marks for communication.
- Each station is a fresh start: a bad station does not carry over if you reset before the next door.

## What it is

The ECOE (evaluación clínica objetiva estructurada, the OSCE in English) tests clinical skills rather than knowledge on paper. Candidates rotate through a circuit of stations, each with a short written task on the door, a fixed time and a bell that starts and ends it. Many stations use a standardised patient: a trained actor who plays the same case, with the same history, emotions and questions, for every candidate, so that everyone faces the same challenge. Others use a mannequin, a part-task trainer, an image, a tracing or a set of results. An examiner, or the standardised patient, marks each performance with tools prepared in advance: a checklist of observable actions (did the candidate wash hands, introduce themselves, ask about allergies) and often a global rating of overall competence, communication and organisation. Good stations are built from a blueprint of the curriculum, piloted, and checked for reliability and validity, so the marks reflect real skill rather than luck or examiner mood. The practical lesson is that only what is seen or heard can be marked: say what you are doing, follow a visible structure, and treat the actor as a real patient from the first second to the last.

## What is assessed

- Structure: a circuit of timed stations, usually several minutes each, with reading time before entering.
- Station types: history, examination, procedure on a model, communication (consent, bad news, counselling), data interpretation and emergencies.
- Checklist marking: specific actions ticked as done, partly done or not done.
- Global rating: the examiner's overall judgement of competence, often on a short scale from clear fail to excellent.
- Professional behaviour is assessed throughout: identity checks, consent, hand hygiene, privacy, respect and safety.
- Validity and reliability depend on clear tasks, trained examiners and standardised patients, and enough stations to sample the curriculum.

## How to do it (and why)

- Use reading time to plan a structure for the task — a plan keeps you on track when the clock runs.
- Knock, greet, introduce yourself and check the patient's name and age — identity and courtesy are marked items.
- Wash or gel your hands and ask permission before touching — hygiene and consent are checked at almost every station.
- Follow a visible framework aloud — the examiner can only tick what is said or seen.
- Address the patient, not the examiner, unless told otherwise — the actor's rating often counts.
- Watch the time and leave the last minute for a summary and plan — closing points are easy marks often lost.
- Answer the examiner's questions briefly and directly — they usually test the reasoning behind your actions.
- Leave the room calmly and reset before the next door — each station is marked independently.

## How an ECOE station is marked.

| Marking tool | What it captures | How to score well |
| --- | --- | --- |
| Checklist | Specific, observable actions | Do and say each standard step |
| Global rating | Overall competence and flow | Be organised, confident and safe |
| Patient rating | Communication and rapport | Listen, show empathy, avoid jargon |

## Mistakes that cost marks

- Not reading the task: taking a full history when the task asked only for an explanation or a focused examination.
- Doing the right thing silently, so the examiner cannot see that the check was made.
- Forgetting the basics: introduction, identity check, hand hygiene, consent and thanks at the end.
- Running out of time before the summary, plan or safety-netting.
- Talking to the examiner as if the standardised patient were not there.
- Letting a poor station shake your confidence for the rest of the circuit.

## Self-check list

- I read the whole task and knew what was and was not asked.
- I introduced myself, checked identity and explained my role.
- I cleaned my hands and asked permission before any contact.
- I used a clear structure and said aloud what I was doing.
- I spoke to the patient in plain language and checked understanding.
- I kept time and closed with a summary and plan.
- I answered the examiner's questions concisely.
- I reset before the next station.

## Test yourself

Think of the answer, then tap the question to see it.

## Why should a candidate say aloud what they are checking during an ECOE station?

Examiners mark observable actions on a checklist; a check done silently cannot be seen, so it may not earn the mark.

## What is a standardised patient?

A trained person who plays the same case, with the same history, emotions and questions, for every candidate, so the challenge is equal for all.

## What does a global rating add to a checklist?

It captures the examiner's overall judgement of competence, organisation, fluency and communication, which a list of separate actions can miss.

## Which basic actions are marked at almost every station?

Introduction, identity check, hand hygiene, permission or consent, respect for privacy and dignity, and a clear closing.
