How Much Shadowing do you need for Medical School? The MedEdits 75-1-3 Rule

How much shadowing do you need for medical school? My general recommendation is 75 hours of physician shadowing that includes at least one primary care physician and three specialists. That is the 75-1-3 rule, and it is the benchmark I have used with MedEdits clients for nearly two decades. The longer answer depends on the rest of your clinical portfolio, when you shadow, who you shadow, and what you do with the experience when you write about it in your application.

This guide covers everything a premed needs to know about shadowing: why it matters, how much is enough, when to do it, how to find opportunities, and how to write about it so admissions committees take notice.

Key Takeaways

The MedEdits 75-1-3 rule: aim for 75 hours of shadowing with at least one primary care physician and three specialists. Shadowing is nearly universal among accepted applicants. At George Washington School of Medicine, 88% of matriculants had shadowing experience. Earlier is better: freshman and sophomore year is the ideal window. Extensive hands-on clinical experience can partially offset limited shadowing hours, but rarely eliminates the need entirely. Virtual shadowing does not substitute for in-person shadowing in a real clinical environment. How you write about shadowing in your AMCAS application matters as much as how many hours you logged.

Why Shadowing Matters to Admissions Committees

Shadowing exists for one reason: to help you understand what practicing medicine actually looks like before you commit to the path. Admissions committees know that applicants who have never set foot in a clinical environment have an unrealistic picture of the profession. Part of what they are evaluating when they read your application is whether you have made an informed, eyes-open decision to pursue medicine, not just an idealized one.

When I served on the admissions committee at Icahn School of Medicine at Mount Sinai, one of the things we looked for was evidence that an applicant understood medicine as it is actually practiced: the complexity of patient relationships, the weight of clinical decision-making, the role of teamwork and ancillary services, and the less glamorous realities of the work. Shadowing is one of the primary ways premeds develop that understanding.

That said, shadowing is a passive and observational activity. You are watching, not doing. This is exactly why it should occupy a defined portion of your premed experience. Enough to inform you and demonstrate to admissions committees that you sought out clinical exposure, but not so much that it crowds out experiences where you can actually contribute. The goal is breadth of understanding, not volume of hours.

At George Washington School of Medicine, 88% of medical school matriculants had shadowing experience. That figure is not unusual. Across most medical schools, shadowing is effectively expected unless a student has a compelling clinical portfolio that substitutes for it.

How Many Hours of Shadowing You Need

There is no single number that every medical school requires, because most schools do not publish a minimum. What exists instead is a strong implicit expectation, and that expectation tends to cluster around 75 to 100 hours for applicants whose primary clinical exposure comes from shadowing.

Applicants who fall significantly below 50 hours and have no other substantial clinical experience are likely to be flagged. Applicants who have logged hundreds of shadowing hours at the expense of research, volunteering, or direct patient care may raise a different concern: that they have not pursued the kind of experiences where they could actually demonstrate initiative and impact.

The 75-hour benchmark I recommend is not arbitrary. It reflects what I have seen over 18 years of advising applicants. It is enough to demonstrate genuine engagement with the clinical environment, enough to write about substantively in your application, and not so much that it displaces more active experiences.

The MedEdits 75-1-3 Rule Explained

The 75-1-3 rule is my framework for thinking about the minimum shadowing portfolio a premed should have before applying to medical school.

The 75 refers to total shadowing hours. This is a floor, not a ceiling. If you have the opportunity to shadow more, do it. But 75 hours across the physicians described below gives you enough depth to speak meaningfully about what you observed and what it taught you.

The 1 refers to at least one primary care physician: a general internist, family medicine physician, or pediatrician. Even if you are certain you want to specialize, admissions committees want to see that you understand the foundation of medicine. Primary care physicians focus on preventive care, longitudinal patient relationships, and health education. Shadowing one gives you a perspective on medicine that specialty shadowing alone does not provide.

The 3 refers to at least three specialists. The specific specialties matter less than the breadth. Shadowing across different settings, such as a surgeon, a psychiatrist, an emergency physician, and an oncologist, gives you a richer and more honest understanding of medicine as a profession. It also gives you more material to draw from when writing your personal statement and application entries.

When During Your Premed Years to Shadow

The earlier the better. Freshman and sophomore year of college are the ideal windows for shadowing, for a straightforward reason: your schedule is less crowded. By junior and senior year, most premeds are deep in MCAT preparation, research commitments, clinical volunteering, and coursework. Trying to fit significant shadowing hours into that period is harder than it sounds.

There is also a sequencing argument for early shadowing. If you shadow a physician early in your premed years and it confirms your interest in medicine, that experience can inform every other activity you pursue. If it raises doubts, better to know early. Admissions committees appreciate applicants who can point to a specific moment when they observed something in a clinical setting and it shaped how they thought about their path. That kind of reflection is more compelling when it has had time to develop.

That said, some students find their shadowing opportunities later due to scheduling constraints, geographic limitations, or because their other clinical commitments, such as working as an EMT, scribing, or volunteering in a hospital, simply took priority. Later shadowing is not disqualifying. It is just harder to schedule and harder to write about with the same depth of reflection.

Who to Shadow and How to Find Opportunities

The most common path to shadowing is also the simplest: reach out to physicians you already have a relationship with. Your own internist, pediatrician, or family physician is a natural starting point. Most physicians who have cared for patients who are now applying to medical school are genuinely supportive of the process and willing to have a premed shadow them for a few shifts.

Beyond your own physicians, your premed advising office is the next place to look. Many universities maintain relationships with local hospitals and private practices specifically to facilitate shadowing for premeds. If your school has a pre-health advising office, start there.

If you are already working with a researcher who also sees patients clinically, ask whether you can shadow them in their clinical role. This is an underused pathway. Many physician-scientists divide their time between the lab and the clinic, and students who are already working with them are in a natural position to ask.

For applicants interested in osteopathic medicine, the American Osteopathic Association maintains a directory of osteopathic physicians who accept shadow students. If you are planning to apply to DO programs, shadowing a DO specifically is important, as many osteopathic medical schools expect it.

If you are reaching out cold to physicians you do not know, a short, professional email explaining who you are, where you are in your premed journey, and what you are asking for will often get a response. For guidance on exactly how to write that email, see our detailed guide on how to get shadowing hours with email templates.

What If You Have Extensive Clinical Experience But Limited Shadowing?

This is one of the most common questions I receive, and the answer is nuanced. If you have worked as an EMT, a medical scribe, a CNA, or in another hands-on patient-facing role, you have clinical exposure that in some ways exceeds what shadowing provides. You have not just observed medicine. You have participated in it.

In those cases, falling short of 75 shadowing hours is less concerning. I have worked with applicants who were accepted to strong medical schools with fewer than 50 shadowing hours because the depth and quality of their other clinical experience was compelling. What matters is whether your application as a whole demonstrates that you understand what practicing medicine looks like, not whether you hit a specific shadowing number.

What does not work is substituting shadowing with clinical experience that is entirely non-physician-adjacent. If your clinical exposure consists of volunteering at a hospital gift shop or working at a health insurance company, that does not replace shadowing. The point is direct observation of physician practice: the clinical reasoning, the patient interaction, the decision-making. Something in your portfolio needs to reflect that.

Does Virtual Shadowing Count?

Virtual shadowing does not substitute for in-person clinical shadowing, and I do not recommend it as a primary source of shadowing hours for medical school applications.

Virtual shadowing programs gained visibility during the COVID-19 pandemic when in-person opportunities disappeared. Most medical schools were understanding of that context during those application cycles. That flexibility should not be interpreted as a permanent endorsement of virtual shadowing as equivalent to the real thing.

If you are interested in virtual shadowing for personal exploration, to learn about a specialty you have not had the chance to observe in person, that is a reasonable use of it. But when it comes to building the clinical experience section of your application, in-person shadowing in a real clinical environment is what admissions committees expect.

How to Write About Shadowing in Your AMCAS Application

The applicants who write about shadowing effectively treat it as an opportunity to show that they paid attention: that they noticed something specific, wrestled with something they observed, or came away with a question they did not have before they walked in. A description that says "I shadowed Dr. X in the emergency department and observed trauma cases and patient triage" tells the reader what you did. A description that explains what a particular patient encounter taught you about the way physicians communicate uncertainty, or how watching a difficult diagnosis unfold changed your understanding of what clinical judgment actually requires, tells the reader who you are.

You have 700 characters with spaces for the description in AMCAS Work and Activities. Use them. Be specific. Write about what you actually saw and what it meant to you, not a job description of the activity.

If shadowing was one of your most meaningful clinical experiences, you may choose to designate it as a most meaningful activity and write an additional reflection. In that space, explain what the experience revealed about medicine or about yourself that you could not have learned any other way.

Frequently Asked Questions

How much shadowing do you need for medical school?

The MedEdits 75-1-3 rule recommends 75 total hours of shadowing that includes at least one primary care physician and three specialists. This is a recommended minimum, not a universal requirement. Applicants with extensive hands-on clinical experience may be competitive with fewer hours; applicants with limited clinical experience overall should aim to meet or exceed it.

Does shadowing count as clinical experience for medical school?

Shadowing and clinical experience are related but distinct categories on most medical school applications. Shadowing is observational. You are watching a physician practice. Clinical experience typically refers to hands-on or patient-facing work where you actively participate, such as scribing, EMT work, medical assisting, or clinical research. Both are valuable, but they serve different purposes in your application. Having only shadowing and no direct patient contact is a weakness; having no shadowing at all is also a weakness in most cases.

Can I shadow a nurse practitioner or physician assistant instead of a physician?

Shadowing an NP or PA can be valuable, especially if you have limited access to physicians, but it should not replace physician shadowing for medical school applications. Medical schools are training physicians, and they want to see evidence that you understand what physician practice looks like specifically. If you have NP or PA shadowing, include it, but make sure you also have shadowing with MDs or DOs.

Can I shadow a physician in another country?

International shadowing can add value to your application, but only if you have a genuine connection to the country or have done meaningful work there. If you grew up in another country, have family ties there, or have engaged in sustained community or research work in that setting, shadowing in that context can be a strength. Commercial international shadowing programs that place premeds abroad specifically to build application credentials are not recommended. Admissions committees are familiar with these programs and do not view them the same way as authentic international experience. If you are considering international shadowing purely as an application strategy, your time is better spent building clinical experience at home.

What if I cannot find shadowing opportunities?

Geographic constraints, limited physician networks, and scheduling challenges are real barriers for many premeds. Start with your own physicians, your premed advising office, and any researchers you work with who also practice clinically. If you are still struggling, consider reaching out directly to physicians in your area with a short professional email. Many are willing to accommodate a premed for a few shifts. See our guide on how to find and request shadowing opportunities for email templates you can adapt.

Is it better to shadow one physician for many hours or multiple physicians for fewer hours each?

Multiple physicians across different specialties is better for the purpose of a medical school application. The goal of shadowing is breadth of understanding: seeing how medicine is practiced in different contexts with different patient populations and different clinical challenges. One hundred hours with a single surgeon tells a narrower story than 25 hours each with a surgeon, a primary care physician, a psychiatrist, and an emergency physician. Depth with one mentor can be valuable, but should not come at the expense of variety.

Does virtual shadowing count for medical school?

Virtual shadowing does not substitute for in-person shadowing in a real clinical environment. It can supplement your understanding of a specialty you have not had the chance to observe in person, but medical schools expect applicants to have genuine clinical exposure to the practice of medicine, not a screen-based approximation of it.

How do I list shadowing on my AMCAS application?

Most applicants group all of their shadowing into a single activity entry rather than listing each physician separately. This is generally the right approach. You have 15 activity slots in AMCAS Work and Activities, and those slots are better used on experiences where you made an active contribution: research, clinical work, leadership, volunteering, and other activities that demonstrate initiative and impact. Use the 700-character description for your shadowing entry to go beyond logistics. Describe specifically what you observed across your shadowing experiences and what it taught you about the practice of medicine. If a particular shadowing experience was especially formative, you may consider designating the entry as one of your most meaningful activities and using the additional reflection space to explain why.
