Medical School vs. Residency: What to Expect

Let’s look at the major differences between going to medical school and completing residency so you know what to expect during and after this transition.

Application Process

You’ll notice a lot of overlap in what’s required for the residency application process (The Match) compared to your medical school applications, like standardized test scores, a personal statement, and interviews.

However, it’s quite a different experience in several ways, not least of which because you’re applying for a job versus a position as a student. AdComs for medical schools are looking for students likely to excel in the career path in the first place, while residency program directors are seeking entry-level physicians who are a good fit for their specific specialty and the mission of their program.

You can read more about the medical school application process and The Match in our comprehensive guides, but here are the key differences to be aware of:

• Residency applicants have a far higher chance at success than medical school applicants. The average medical school acceptance rate is roughly 42-44% in any given year, meaning fewer than half of all applicants matriculate to a medical program. Conversely, the Match rate for all residency positions offered is over 90%. By the time you graduate from medical school, you no longer have to prove whether or not you’ll be able to make it as a doctor — it’s more about connecting your experience with the right specialty and specific program.
• Residency applicants are matched to a single program, while successful med school applicants can choose from multiple acceptances. Before Match Day, residency applicants are required to submit a list of the programs they interviewed at in order of preference, while programs are required to submit a preference list for applicants they interviewed. Each applicant is then assigned to a single program based on both sets of preferences according to the Match algorithm. Residency applicants are contractually obligated to attend the residency program to which they are matched. Medical schools, by contrast, simply accept or reject applicants, so those with multiple acceptances decide where to enroll.
• A significant part of the residency application process is choosing to apply to one or more specialties, whereas medical school applicants are all applying for the same graduate program. The four years you spend in medical school are some of the most important for choosing exactly what kind of doctor of medicine you want to be. When filling out the ERAS and later creating your rank order list, you’ll have to make decisions like whether or not you’re interested in a competitive specialty, if you’re looking for a shorter residency period, like with a primary care focus, or if you’ll try alternating specialties vs. your top choice specialty first.
• The Match allows partners to apply for residency positions in similar geographic locations; primary med school applications do not. If you’re interested in attending the same medical school as your partner, you’ll both have to apply separately. However, the Couples Match allows for this if you want to live with or near your significant other when starting out in actual medical practice.

Duration

Most medical programs last 4 years, though some accelerated medical schools give you the chance to become a medical school graduate in just 3 years. Dual-degree programs can take longer — for instance, most MD/PhD programs last 7-8 years, while MD/MBA and MD/MPH programs add one year to the typical four-year timeline of medical school.

Residency programs last for between 3-8 years. More years of training are generally required for more complex specialties, like surgery (which requires a minimum of 5 years in residency). Family medicine and pediatrics residencies are almost always 3 years long, whereas a plastic surgery residency lasts an average of 6 years.

Some subspecialties, such as neurosurgery, max out the full 7-8 years of residency.

Different specialties may require or allow you to try for a preliminary residency program, which lasts 1-2 years and is then followed by an advanced residency for 2+ more years. This is more common in specialties like surgery, neurology, radiology, anesthesiology, and dermatology. In these cases, you’ll need to apply to both the preliminary (or transitional) and advanced programs at the same time, making the application process a bit more expensive and complex.

Depending on the type of subspecialty you wish to pursue, you may also move into a fellowship program (generally 1-3 years) after residency. While these are still technically training programs, fellowships do not require stringent supervision in the same way the early years of residency might.

Structure

The structure of a four-year med school typically follows this format:

• Preclinical (Years 1 & 2): During your first year of medical school, you learn the scientific foundations of medicine to prepare you for a career as a physician. Year two focuses on classroom learning on pathophysiology and clinical preparation.
• Clinical (Years 3 & 4): In year three of medical school, you complete core clinical rotations in major medical specialties, including internal medicine, surgery, pediatrics, psychiatry, obstetrics/gynecology, and family medicine. During year four, you’ll explore your interests or subspecialties in elective rotations. While you get to do hands-on patient care during these rotations, your responsibilities will be limited (e.g., you can’t diagnose conditions or develop treatment plans).

Residency is less structured than medical school, as a medical residency program bridges the period between your formal education and independent clinical practice. However, all residents experience some degree of the following:

• Progressive Responsibility: The longer you are a resident and the more you prove your competence, the more complex and autonomous your responsibilities become.
• Rotational Training: During your residency, you’ll receive medical training in various subspecialties related to your broader field. For instance, an anesthesiology resident will likely do rotations in pediatric anesthesiology, neuroanesthesiology, and obstetric anesthesiology (among others). These subspecialty rotations are ultimately designed to help you choose the precise branch of medicine that fits you best.
• Didactic Education: Residents go through regular educational sessions, including grand rounds, morbidity and mortality conferences (M&Ms), and specialty-specific lectures, to learn more about their field and assess how to improve patient care.
• Evaluation: As a resident, you’ll consistently be required to self-evaluate and receive assessments from faculty members overseeing your training. These evaluations play a large part in the progressive responsibility you are given as you learn.

Testing

Prior to medical school, you must pass the MCAT (in almost every case), which assesses problem-solving and knowledge related to the medical field that you need to succeed in the early years of a medical program.

Medical students are also required to take a number of standardized exams throughout their education, including:

• USMLE Step 1/COMLEX Level 1: The first licensure exam evaluates whether students can integrate and apply foundational science knowledge to clinical scenarios. Note: As of January 2022, Step 1 is graded as pass/fail only.
• Shelf Exams: The NBME shelf exams are given at the end of each clinical clerkship (typically your third year of med school) to assess how well you understand the core disciplines of each specialty you rotate through.
• USMLE Step 2 CK/COMLEX Level 2: The second licensure exam tests your knowledge of clinical sciences and the application of that medical knowledge in patient care. Most medical students take Step 2/Level 2 during their fourth year, and this numeric grade is used as a vital part of the residency application process.

As you can see, there are two variations for licensure exams based on whether you’re in a medical program to become an MD or a DO. However, the basics of what these exams test and how are very similar.

Residents also complete testing as part of their medical training, which includes:

• USMLE Step 3: After completing the intern year, residents take their third licensure exam, focusing on patient management, diagnosis, and clinical decision-making. Passing Step 3/Level 3 is required to become a fully licensed physician — you’ll be a doctor after finishing medical school, but you can’t practice independently until now.
• In-Service or In-Training Exams (ITEs): Each resident will complete annual ITEs according to their specialty to assess their progress in training. These can influence applying to fellowships and remediation decisions (meaning what happens if you perform poorly on future ITEs or your board exams). ITEs are designed around your specialty; for instance, there are different exams for students in an internal medicine residency vs. family medicine or obstetrics.
• Board Certification Exams: At the conclusion of your residency training, you’ll take board exams for your specialty. Technically, these are voluntary exams not required to practice medicine in general; however, they greatly influence where you’ll be able to work and whether or not you’ll qualify for insurance payouts from patient care. Think of these as voluntary but essential in most cases. If you want to practice in multiple or combined specialties, you’ll need to take all of the required certification exams.
