The National Assessment Collaboration Examination

You must take the National Assessment Collaboration (NAC) Examination if you want to apply to a Canadian residency program.

For more information on NAC exam eligibility requirements, please visit Application and eligibility.

What is the NAC Examination?

The NAC Examination is a one-day exam that assesses your readiness to enter a Canadian residency program. It is a national, standardized examination that tests the knowledge, skills, and attitudes essential for entrance into postgraduate training in Canada.

It is an objective structured clinical examination (OSCE) that includes a series of stations where you are presented with typical clinical scenarios. It includes problems in:

  • Medicine
  • Pediatrics
  • Obstetrics
  • Gynecology
  • Psychiatry
  • Surgery

You can take the NAC Examination in English or French at designated centres.

To find out how to prepare for the NAC Examination, including common mistakes that candidates make, and to learn more about the exam objectives, visit our NAC Examination preparation resources page.

Why should I take the NAC Examination?

The NAC Examination is required to apply to a Canadian residency program. The Canadian Resident Matching Service (CaRMS) accepts NAC Examination results as part of match application packages.

The NAC Examination is not required to obtain the Licentiate of the Medical Council of Canada, and a pass does not guarantee a residency training position in Canada.

How do I take the NAC Examination?

You can apply to the NAC Examination during designated application periods through your account. Your results will be accepted by residency programs directors regardless of where you take the exam. You do not have to take the examination in the province where you will be applying for residency.
