Information for residency program directors
The National Assessment Collaboration (NAC) Examination assesses the readiness of an international medical graduate (IMG) for entrance into a Canadian residency program. It is a pan-Canadian, standardized examination that provides residency program directors with objective information on the skills, attitudes and knowledge level of IMGs applying for postgraduate training in Canada.
The NAC Examination is currently delivered through provincial IMG assessment programs in Alberta, British Columbia, Ontario, Manitoba, Nova Scotia and Quebec.
The NAC Examination was developed to reduce duplication amongst provincial IMG assessment programs and offer standardized results to residency program directors across the country. The exam results provide a comprehensive assessment of an IMG’s skills, attitudes, knowledge and readiness at the level of a recent Canadian medical graduate for entry into postgraduate training.
This information should be used with other information – such as a residency application letter or results from the Medical Council of Canada Evaluating Examination (MCCEE) – to obtain a comprehensive view of an applicant’s skill set.
Scope and format
The NAC Examination is a clinical skills examination that consists of 12 different 11-minute clinical stations, each with a standardized patient and a physician examiner.
In total, the duration of the exam is approximately three hours. However, the candidate may be on site for a longer period of time for administrative reasons.
Visit our station description page for more detailed information on the format of the NAC Examination.
Evaluation and scoring
The pass/fail result is based on whether a candidate’s examination score is equal to or higher than the established for the NAC Examination. The standard is based on the level of performance compared to a graduate from a Canadian medical school. The NAC Examination also collects information from physician examiners on the candidate’s ability to demonstrate ethical and professional behaviour.
Candidates are rated by physician examiners on up to nine different competencies per station. These competencies include:
- History taking
- Physical examination
- Organizational skills
- Communication skills
- Language fluency
- Data interpretation
- Therapeutics and management
A candidate’s score for each station is the average of all competency ratings measured on the station. A candidate’s score for the entire exam is the average of the station scores.
In awarding the final result on the examination, consideration is given to any observations made by the physician examiner at each of the stations on the candidate’s ability to demonstrate the ethical and professional behaviour needed to enter postgraduate training.
More detailed information on NAC examination scoring can be found on the Scoring page.
Content for the NAC Examination is developed by the NAC Examination Committee – a group of physicians from across the country with expertise in multiple medical disciplines. The Examination Committee meets on a regular basis to develop and review content and set standards based on the expected performance of a graduate from a Canadian medical school.
