What Is a Medical Resident and How Long Is Residency?

Discover everything you need to know about earning and achieving success in a residency placement program.

Updated 01 May 2026

If you dream of becoming a practicing physician, you may think that studying in a 4-year MD program will be the pinnacle of your medical education journey. However, if you plan to work in the U.S. and Canada, medical school should be considered the first stage of a comprehensive training process that leads to becoming licensed as an independent practitioner. The next crucial stage after med school is called “residency.”

Residency training is when future doctors begin to focus on a specific medical specialty, while further developing the knowledge and skills they gained during the Basic Science and Clinical Medicine portions of medical school. They also take on more autonomy in the treatment process, while still benefitting from guidance and instruction provided by experts in the field of medicine in which they plan to specialize.

If you’re curious about this all-important training experience for aspiring physicians, the following sections will highlight key details related to residency pathways, timelines, experiences and opportunities. Read on to learn more!

What Is a Resident Doctor?

A medical resident is a successful med school graduate who goes on to participate in a post-graduate training program accredited by the Accreditation Council for Graduate Medical Education (in the U.S.). Such residents work in hospitals and medical centers while training in a specialized medical field, such as family medicine, emergency medicine or general surgery.

During this period, a resident physician provides direct patient care, including diagnosing, managing, and treating health conditions and injuries, while still under the supervision of licensed experts. First-year residents are known as PGY-1 (postgraduate year one) participants or interns, because the first year of residency is often considered an internship. Interns officially become residents in their second year of residency, as they earn more responsibilities and privileges related to independent care.

What Does a Resident Physician Do? 

Medical residents often work in medical centers or hospital departments, such as emergency clinics, intensive care units, general patient wards and operating rooms. As a doctor in training, a resident will develop their skills in completing examinations, performing laboratory work, ordering and interpreting diagnostic tests, providing medical procedures, recording patient histories, and advising on mental and physical self-care. They will also gain relevant communication experience, such as coordinating with different departments and delivering updates to families. 

Notably, much of the direct instruction residents receive will occur during rounds – when one or more instructors will take residents from patient to patient to assess their condition and treatment. During this time, they will ask relevant questions about symptoms, progression and the ongoing provision of care. Residents can show what they know and strengthen areas where they may be lacking. 

How Does a Medical Residency Work? 

To enable physicians to provide care during their residency training (and beyond), the medical school from which they graduate must hold any relevant approvals and certifications required by the jurisdiction in which the residency program operates. Importantly, Medical University of the Americas alumni are eligible to practice in all 50 U.S. states, Canada and internationally. 

The following are some more key details about how medical residency works, including some we have already touched on:

• All resident doctors in the U.S, and Canada must have completed medical school and earned a relevant degree, such as a Doctor of Medicine (MD) degree. 
• During residency, new doctors focus on a specific area of specialization within medicine.
• Residency programs differ in length, depending on the chosen specialty (more on this to follow).
• No matter the specialty, residency is spent developing the critical thinking, care provision and communication skills needed to practice independently.
• Throughout residency, physicians steadily take on more independent treatment responsibilities, while still under the supervision of licensed practitioners who provide guidance and instruction. 
• Crucially, residents have the opportunity to work with patients long enough to observe how illnesses and conditions evolve over time, and learn what is needed on their part to provide consistently effective care. 
• By the end of residency, successful physicians will have developed the knowledge and skills they need to pass requisite licensing examinations (USMLE Step 3 in the U.S.), then begin to practice independently or move into a fellowship program.

Medical Residency Placements 

Medical students typically choose the medical field they wish to specialize in by the end of their third year of medical school. Their decision should be guided by personal goals and abilities, as well as their experiences while completing core rotations (hands-on training at affiliated teaching hospitals in the U.S. and Canada), which occur during the third year of medical school in Clinical Medicine. At MUA, core rotations include internal medicine (12 weeks), surgery (12 weeks), OB/GYN (6 weeks), pediatrics (6 weeks) and psychiatry (6 weeks). 

What students enjoy and where they thrive during core rotations will help them choose related elective rotations to complete during the fourth and final year of medical school. Rotation experiences will also influence the residency programs they choose to apply for during the residency placement process. How they perform during rotations, as well as their results on the USMLE Steps 1 and 2, will help determine where they are placed for residency.

Residency Match Process

Medical students who wish to achieve a residency placement in the United States will participate in the National Resident Matching Program (NRMP); students who wish to undertake residency in Canada will participate in the Canadian Resident Matching Service (CaRMS) process. The NRMP is most commonly known as The Match, with fourth-year medical students around the world waiting in eager anticipation for Match Week and Match Day (in March each year), the period when they find out if and where they will begin their residency training in the U.S. 

The Match journey typically begins in September of an MD program participant’s final year, when medical students submit their applications via the Electronic Residency Application Service (ERAS). Following this, the residency program interview process proceeds between October and February, when medical institutions meet directly with chosen applicants and both parties assess the potential fit. Students and programs then rank their preferences and the NRMP algorithm uses these rankings to match applicants and programs. The results are then released in March.

Preparing for Residency 

Before starting residency, there are some different ways you can lay the foundation for your success. The most obvious are strong academic performance in medical school, USMLE success and extensive rotation experience in your desired specialty.

Beyond that, an excellent place to start is by finding a great mentor or mentors. It is extremely valuable for your training and development to learn from a successful professional. For instance, if your mentor is a technically superb orthopedic surgeon, they can instruct you in all the approaches that helped them achieve their status. They are also likely to have useful contacts with residency program instructors, which can be invaluable. 

“One thing every program director wants to hear about a candidate is that the mentor fully supports the candidate as a solid individual with good ethical behavior and the skills (both mental and physical) to complete surgical training successfully,” noted Robert Roman, MD, Associate Professor at MUA.

It is also helpful to get into the mindset of being a lifelong learner. The field of medicine is constantly evolving, and staying current will allow you to continue delivering effective care. Putting in regular study time after hours and being sure to find answers to any questions you may have is always recommended. Beyond that, participating in development courses, reading the latest medical journal articles and learning how to incorporate the latest technology into your practice are all useful ways to thrive throughout your future career.

How Long Is Medical Residency?

You may be wondering, “how long is medical residency?” While most residences last between 3 and 7 years, the length of a specific residency program will depend on the specialty you choose to pursue. For instance:

If you are considering pursuing a highly specialized field of medicine, such as reconstructive surgery, pediatric radiology or female pelvic medicine, you will need to complete additional fellowship training after your residency.

How Much Do Resident Doctors Make?

Beneficially, resident physicians do receive financial compensation, although not as much as they will earn as independently licensed practitioners. In 2025, the average resident salary in the U.S. was $75,000 USD per year. In Canada, the median annual salary was $232,277 CAD (November 19, 2025).

What Is the Difference Between a Medical Resident and a Fellow?

The key distinction is that residency is a mandatory training period (3-7 years) that medical school graduates must complete successfully in order to practice independently in the U.S. and Canada, while fellowships are optional training programs (1-2 years) for those who have completed residency. Residents focus on a specific area of practice in medicine, while fellows focus on subspecialties within a broader medical specialty. For example, cardiology, nephrology and rheumatology programs are all possible fellowships for those who have completed an internal medicine residency.

What Happens After a Medical Residency? 

Once you complete your medical residency program, there are several avenues you can take. For example: 

Fellowships 

As noted, some doctors decide to continue their training after residency by going on to complete a fellowship program. A fellowship is at least one more year of study, usually in a subspecialty of their residency training specialty area, to learn more cutting-edge techniques and advanced treatments. Doctors who become fellows are often considered to be experts in their chosen fields. 

Practice 

After completing their residency programs, doctors can apply for an unrestricted medical license. They will then have the option to work in private practice, group practice, or become employed by a clinic or hospital. In order to practice independently in any of these settings, physicians must complete requisite licensing exams in their chosen geographical location. In the U.S., this would be the USMLE Step 3, as well as any relevant state licensing requirements.

Board of Certification 

Many doctors decide to earn board certification in their field of specialty after residency comes to an end. Board certification is a voluntary qualification that reflects your knowledge in a certain field, such as internal medicine, orthopedics, pediatrics or pathology.
