Preparing for the NAC OSCE as an international medical graduate

If you already know the medicine, what is harder to rehearse is the encounter itself: speaking with a patient in Canadian clinical English, under time, while someone marks what you do. This guide is about that part. It gives no clinical advice, and it does not replace the Medical Council of Canada's own information, which is the authority on everything about the examination.

Start from what the examination assesses

The examination assesses seven competencies: history taking, physical examination, communication skills, diagnosis, management, investigations, and data interpretation. (Source: NAC Examination, Medical Council of Canada)

Use that list as your checklist. After each practice case, ask which of them you actually showed out loud, and which you only knew.

Practise aloud, not on paper

Reading a case rehearses recall. Practising aloud rehearses something else: the questions you ask, and whether you explain a diagnosis in words a worried person can follow. That only improves by doing it out loud, repeatedly, and hearing where you hesitate.

Record yourself or practise with a partner, and listen back for jargon, for questions you forgot, and for the moment you ran out of structure.

Practise under the real time

Each station is 11 minutes long, with 2 minutes between stations. (Source: NAC Examination, Medical Council of Canada)

Time your practice to the same limit. Running out of time with the history half done is a different problem from not knowing what to ask, and you only find out which one you have under the clock.

Rehearse the examiner as well as the patient

In some stations the physician examiner asks oral questions, and those answers are scored. (Source: NAC Examination Annual Technical Report 2024 (PDF), Medical Council of Canada)

Practise summarizing what you found and stating your working diagnosis and plan in a few clear sentences, so you are ready when an examiner puts a question to you.

Keep your sources straight

Exam-preparation sites, this one included, are not the Medical Council of Canada. When something you read about the examination matters to your plans, check it against the MCC's own pages. Where these guides state an examination fact, they link the MCC page it comes from.

Where NACMATE fits

NACMATE is one way to practise the spoken encounter on your own schedule. It runs a station with a simulated patient, whose replies a language model voices from facts written for that station, and a simulated examiner who reads fixed lines, and it gives feedback organized by competency. Its station content was adapted from physician-written material with the help of language models and cross-checked by three independent model passes. No physician has reviewed the content, so use it to practise the encounter and keep a clinical reference for the medicine.
