Build a stationThe NAC OSCE, answered
What is the NAC OSCE?
The NAC Examination is a half-day OSCE run by the Medical Council of Canada (MCC). It assesses whether international medical graduates have the knowledge, clinical skills and communication needed to enter residency training in Canada.
Who can take the NAC OSCE?
Graduates of medical schools outside Canada that are listed in the World Directory of Medical Schools, graduates of US osteopathic (DO) schools, and graduates of US allopathic (MD) schools who graduated on or after 1 July 2025. International students can sit it if they will complete their degree within 15 months of the exam.
How many stations are in the NAC OSCE?
12 stations: 10 scored and 2 pilot stations that do not count toward your result. There are also 2–3 rest stations with no clinical scenario.
How long is each NAC OSCE station?
Each station lasts 11 minutes, with 2 minutes between stations.
When is the NAC OSCE held, and when are results released?
Twice a year, in spring and fall, in person at designated centres, in English or French. Results are released about 8 weeks after the last day of the session.
What does the NAC OSCE cover?
Stations come from medicine, surgery, pediatrics, obstetrics and gynecology, psychiatry, and preventive medicine and public health. Each station assesses up to 7 competencies: history taking, physical examination, investigations, data interpretation, diagnosis, management and communication skills.
How is the NAC OSCE scored?
Your total score is reported on a scale from 500 to 700, and the pass score is 577. A supplemental report breaks your performance into assessment and diagnosis, management, and communication skills, and compares it with other candidates.
How many times can I take the NAC OSCE?
A maximum of 3 times, whether you passed or failed before, and never in consecutive sessions. If you sit it more than once, only your most recent result is valid.
How much does the NAC OSCE cost?
The MCC fee is CA$3,320, and it is non-refundable. The MCC reviews its fees every year.
Can I use PLAB 2 or AMC material for the NAC?
The OSCE format carries over, but the cases, guidelines and what the examiner expects are Canadian. Practise on Canadian cases so your management plans match what the NAC marks.
How does MLAbuddy help me prepare for the NAC OSCE?
You speak each station out loud with an AI patient, or an AI examiner for data-interpretation stations, and get marked against the station checklist. Every station is set in Canadian practice and follows Canadian clinical guidelines. Some stations are free to try. Premium runs stations on the full 11-minute clock; the free plan caps a station at 8 minutes. There are no physical examination stations: the patient is voice-only.
