ECOS are the practical clinical examinations of the French second cycle of medical studies. Candidates move through a series of short timed stations, each presenting a clinical situation with a simulated patient, and are assessed against a standard grid on examination technique, reasoning and communication.
French acronym: examens cliniques objectifs structures, the French form of the international OSCE format
ECOS, OSCE, examens cliniques objectifs structures
objective structured clinical examination
Each station sets a brief scenario: taking a history, examining a patient, announcing a diagnosis, explaining a treatment or handling an emergency situation. An actor or a trained simulated patient plays the role, an examiner observes with a grid prepared in advance, and a bell marks the change of station. Because every candidate passes through the same stations with the same grid, the assessment of practical skills becomes comparable, which is the purpose of the format.
They accompany the reform of the second cycle, which sought to assess more than written knowledge. Alongside the EDN and the record of the student's course, the ECOS contribute to the ranking that governs the allocation of residency posts. They give weight to bedside skills that a written paper cannot capture, and they reward the clinical placements served during the DFASM.
The format is not specific to France. Many European faculties assess clinical competence through the same station-based method, under the international name OSCE, so a student who has trained in another EU member state usually arrives with the same reflexes. That matters in practice: whatever the country, the ability to conduct a consultation in French, to explain and to reassure, is what the examiner observes, and it is also what an employer or a patient will notice later.
ECOS are sometimes read as a test of manner or of confidence. The grid measures precise actions: the questions asked, the examination steps performed, the information given, in a set order and within a set time. Preparing for them means rehearsing real consultations, not rhetoric, which is why regular clinical placement attendance during the second cycle counts more than a late revision effort.
