The National Assessment Collaboration Objective Structured Clinical Examination (NAC-OSCE) remains one of the most important examinations for international medical graduates (IMGs) seeking residency opportunities in Canada. While many candidates focus primarily on passing the exam, understanding how NAC-OSCE scores are reported and interpreted can provide valuable insight into your performance and competitiveness.
Understanding the NAC-OSCE Scoring System
Since May 2023, NAC-OSCE results have been reported on a scale ranging from 500 to 700, with a passing score of 577. Candidates who achieve a score equal to or greater than 577 receive a passing result, while those scoring below 577 receive a failing result. Importantly, the pass standard is not determined by how other candidates perform. Every candidate who meets or exceeds the passing score passes the examination regardless of the overall performance of the cohort.
The Medical Council of Canada (MCC) uses a rigorous scoring and quality assurance process to ensure that all candidates are assessed fairly and consistently. Multiple verification procedures are completed before results are released.
What Information Is Included in Your Results?
Approximately eight weeks after the last day of the examination session, candidates receive their results through their physiciansapply.ca account (MCC NAC results).
Two important documents become available:
Statement of Results (SOR)
The Statement of Results includes:
- Your final result (Pass or Fail)
- Your total NAC-OSCE score
- The passing score for that examination session
Supplemental Information Report (SIR)
The Supplemental Information Report provides more detailed feedback, including:
- Performance across different competencies
- Subscores from the examination
- Comparison with other candidates
This report can be particularly valuable for candidates who plan to improve their performance or prepare for future residency applications.
What Is Considered a Strong NAC-OSCE Score?
According to the MCC’s score interpretation guidance, the mean was 600, with a standard deviation of 25 points, when the current scale was introduced in May 2023.
Using this information:
- 577 = Passing score
- 602 = Approximately one standard deviation above the pass score
- 622 = Equivalent to the historical “Pass with Superior Performance” level
- 627+ = Approximately two standard deviations above the pass score
While residency programs evaluate applicants holistically, achieving a score significantly above the passing standard may strengthen an IMG’s overall application profile.
Why the Supplemental Information Report Matters
Many candidates focus only on whether they passed or failed. However, the Supplemental Information Report can provide valuable feedback about strengths and areas for improvement.
Candidates preparing for future clinical assessments or residency interviews can use this information to:
- Identify communication weaknesses
- Improve patient-centred clinical interactions
- Strengthen physical examination skills
- Refine clinical reasoning and decision-making
The report provides a clearer picture of your overall clinical performance than the pass/fail result alone.
Preparing for NAC-OSCE Success
The NAC-OSCE is designed to assess real-world clinical skills, communication, professionalism, and clinical reasoning. Success requires more than medical knowledge alone. Candidates must demonstrate safe and effective patient interactions throughout each station.
One of the most common mistakes candidates make is focusing solely on diagnosis while neglecting communication and clinical reasoning. During every station, candidates should clearly explain their thought process and communicate effectively with the patient while performing clinical tasks.
Consistent practice with mock stations, structured feedback, and realistic clinical scenarios can significantly improve performance.

For IMGs preparing for Canadian licensing examinations, combining NAC-OSCE preparation with strong MCCQE1 preparation remains an important strategy. Resources such as mccQbank help candidates strengthen their clinical decision-making skills through Canadian-focused practice questions and exam-oriented learning tools that support success throughout the Canadian medical licensing journey.
