For international medical graduates (IMGs) pursuing a medical career in Canada, the National Assessment Collaboration (NAC) Objective Structured Clinical Examination (OSCE) is a crucial milestone. It is not just another hurdle—it is a standardized, high-stakes clinical exam that significantly influences your chances of securing a residency position in Canada.
A clear understanding of what constitutes a good NAC OSCE score is essential for strategic preparation and realistic goal-setting.
In this guide, we break down what a good NAC OSCE score looks like, how scores are calculated, what programs expect, and how you can optimize your performance to stand out.
What Is the NAC OSCE?
The NAC OSCE is a standardized clinical exam administered by the Medical Council of Canada (MCC). It is required for IMGs applying to Canadian residency programs through the Canadian Resident Matching Service (CaRMS).
The exam assesses:
- History-taking
- Physical examination
- Communication and interpersonal skills
- Clinical decision-making
- Professionalism
The NAC OSCE is composed of 12 stations (as of the latest update), with standardized patients presenting clinical scenarios that test real-world readiness.
What Is a Good NAC OSCE Score in Canada?
If you’re an international medical graduate (IMG) looking to enter a residency program in Canada, the National Assessment Collaboration (NAC) OSCE is a critical step in your journey. One of the most common questions IMGs have is: What is a good score in the NAC OSCE?
Let’s break it down using the latest scoring system introduced in May 2023.
How Is the NAC OSCE Scored?
Since May 2023, the NAC OSCE is scored on a scale ranging from 500 to 700, with:
- 600 as the mean (average)
- 25 as the standard deviation (SD)
- 577 as the pass score
What Is a Good NAC OSCE Score?
| Score | Meaning |
| Below 577 | Fail |
| 577 | Pass (minimum threshold) |
| 602 | Good – 1 SD above pass |
| 622 | Competitive – Equivalent to “pass with superior performance” |
| 627+ | Excellent – Top-tier candidates, 2 SDs above pass |
- A score of 602 means you’re performing better than the average successful candidate.
- A score of 622 is considered competitive and is equivalent in performance to what was previously categorized as “pass with superior performance” (used during the September 2020 exam session).
- A score of 627 or above places you among the highest-performing candidates.
Don’t Compare with Old Scores
Before May 2023, NAC scores were reported on different scales, such as:
- 300–500 (March 2019 – March 2020)
- 1300–1500 (Oct 2021 – Sept 2022)
- Or even 0–100 (2013 – 2018)
Because of changes in scoring format and exam delivery, scores from past years cannot be directly compared to the current 500–700 scale. What matters now is how your score relates to the current passing mark of 577.
To be seen as a strong candidate for residency matching in Canada:
- Aim for 602+ to stand out
- 622+ is excellent and competitive
- But most importantly, make sure you understand the exam format and prepare strategically
A good score isn’t just about passing — it’s about showing residency programs that you’re well-prepared and clinically competent.
How to Achieve a Good NAC OSCE Score
1. Start with a Structured Study Plan
- Allocate at least 3–6 months of preparation time
- Use a daily or weekly study schedule tailored to your weaknesses
- Balance individual study with group practice
2. Master the MCC Blueprint
- Familiarize yourself with MCC’s objectives and clinical presentations
- Prioritize common scenarios: chest pain, abdominal pain, headache, prenatal care
3. Practice with Simulated Patients
- Join a NAC OSCE prep course (e.g., MedCognito’s expert-led simulations)
- Practice full mock exams under timed conditions
- Get feedback from Canadian-trained physicians or experienced IMGs
4. Focus on High-Yield Clinical and Communication Skills
- Use mnemonics for history-taking (e.g., OPQRST, SAMPLE)
- Refine physical exam techniques
- Practice patient-centered communication, empathy, and time management
5. Self-Assess and Iterate
- Record and review your mock sessions
- Identify patterns in feedback
- Track progress using performance rubrics
Final Thoughts: Strategize, Prepare, and Excel
The NAC OSCE is not merely an exam—it is an opportunity to showcase your readiness to practice in Canada. Understanding what constitutes a good score is the first step. The next is to prepare methodically, seek expert guidance, and consistently evaluate your progress.
