MD vs DO: Med School Differences and How to Choose

If you’re a premed trying to decide between MD and DO, you’ve probably heard both sides. Some will tell you they’re essentially the same degree. Others will say the differences are significant enough to define your entire career. The truth lies closer to the second camp, and we’ll show you exactly why with data to back it up.

In this article, we’ll break down how competitive each path is to get into, what you’ll actually study, how the application process differs, which licensing exams you’ll take, and, most importantly, what the residency match data looks like across specialties. We’ll also clear up some of the most common misconceptions that are misleading premeds into making uninformed decisions.

The Main Difference Between MD and DO (Allopathic vs Osteopathic Medicine)

At the end of the day, both are medical degrees. MDs and DOs are fully licensed physicians who can prescribe medications, perform surgery, and practice in any specialty across all 50 states. You are both doctors.

The core difference is that DO programs follow an osteopathic philosophy of medicine, which they say emphasizes “the whole patient rather than just symptoms.” As part of that philosophy, DO students complete 300 to 500 additional hours of training in Osteopathic Manipulative Medicine, or OMM, a set of hands-on techniques designed to diagnose and treat patients through physical manipulation of the body. 

It’s important to note, however, that most practicing DOs don’t use OMM at all once they’re out in the real world, and many of its practices are considered speculative and not supported by modern science. But we’ll get into these downsides in more detail later. 

The more consequential differences aren’t about philosophy. They’re about admissions competitiveness, licensing exams, residency opportunities, and the doors that stay open or closed depending on which path you take.

MD vs. DO Differences

MD vs DO Training Path

1 | Admissions: How Competitive Is Each Path? 

The average MD matriculant enters medical school with a 3.81 GPA and a 512.10 MCAT score, landing in the 84th percentile.

The average DO matriculant enters with a 3.60 GPA and a 502.97 MCAT score. A 503 lands in the 58th percentile, only slightly above the average test taker at 500.50. 

To put the MCAT gap in concrete terms: roughly 84% of test takers scored below a 512. Roughly 58% scored below a 503. The applicant pools these numbers represent are quite different. These are numbers for the most recent 2025-2026 percentiles. Average scores tend to increase slightly each year, but the gap between MD and DO remains stark.

This doesn’t mean DO programs are easy to get into. Both paths are competitive, and neither accepts the majority of applicants. But if you’re deciding which path to pursue, understanding where the bar is set for each is the starting point.

2 | Curriculum: What Will You Actually Study? 

For the most part, MD and DO students study the same material. The first two years cover the same foundational sciences: anatomy, physiology, biochemistry, pharmacology, and pathology. The final two years are clinical rotations across the same core specialties, including internal medicine, surgery, pediatrics, OB/GYN, and psychiatry.

The most meaningful difference is OMM or OMT (osteopathic manipulative medicine/treatment). DO students complete 300 to 500 additional hours of training in Osteopathic Manipulative Medicine, a set of hands-on techniques used to diagnose and treat patients through physical manipulation of the musculoskeletal system. 

Some of OMM/OMT is supported by evidence, and some isn’t. Craniosacral therapy, for example, involves touching specific points along the spine to supposedly alter the flow of cerebrospinal fluid. That claim is not supported by current science.

The overwhelming majority of practicing DOs don’t use OMM with their patients at all. You spend hundreds of hours learning it in medical school, and most physicians set it aside once they’re in residency and beyond. 

Those extra hours have to come from somewhere, and they come at the expense of the time MD students spend on other coursework, research, or clinical prep. That’s the trade-off, and it’s worth understanding before you commit to a path.

3 | How You Apply: AMCAS vs AACOMAS

MD and DO applicants use different centralized application services. MD applicants apply through AMCAS, the American Medical College Application Service. DO applicants apply through AACOMAS, the American Association of Colleges of Osteopathic Medicine Application Service. If you’re applying to medical schools in Texas, most public programs use TMDSAS regardless of whether the degree is MD or DO.

You can apply to both MD and DO schools simultaneously, but you’ll need to submit separate applications through each service. They are not interchangeable.

The most important practical difference is the personal statement. AMCAS asks why you want to become a doctor. AACOMAS asks why you want to become a doctor of osteopathic medicine specifically. This means you can’t submit the same personal statement to both without significant revision. 

AACOMAS also strongly recommends you acquire at least one letter of recommendation from a DO physician, which means it’s a good idea to plan ahead and build that relationship before you apply.

Here’s a full breakdown of the key differences between the three application services: AMCAS, AACOMAS, and TMDSAS.

4 | Licensing Exams: USMLE vs. COMLEX 

MD students take the USMLE (United States Medical Licensing Examination), which consists of three Step exams taken at different points during and after medical school. DO students take the COMLEX, the Comprehensive Osteopathic Medical Licensing Examination, which follows a similar three-level structure. 

Both qualify you for medical licensure. The difference is in how residency programs view them.

COMLEX is widely understood among residency program directors to be a less rigorous exam than the USMLE. Many DO students are aware of this, which is part of why a significant number choose to take the USMLE in addition to COMLEX, particularly those applying to competitive specialties or programs that prefer or require USMLE scores. 

Taking both exams adds cost, time, and pressure on top of an already demanding medical school curriculum. It’s another tax on the DO path.

There’s also a percentile issue that doesn’t get talked about enough. Some programs that accept COMLEX scores require a higher minimum percentile from DO applicants than they do from MD applicants on the USMLE. Program directors know the tests aren’t equivalent in rigor, so they raise the bar to compensate.

If you’re a DO student with competitive aspirations, taking the USMLE isn’t optional in any practical sense. It’s the cost of keeping your options open.

5 | Residency Match: Where the Differences Really Matter 

On the surface, the overall match rates look nearly identical. In 2026, 93.5% of MD seniors matched into a residency, and 93.2% of DO seniors matched. That gap has essentially closed to less than half a percentage point. If that’s where you stop reading, you might conclude the two paths have converged.

They haven’t.

The overall match rate tells you nothing about where people matched. Once you break it down by specialty, the picture changes significantly. In 2026, 208 MD seniors matched into plastic surgery. Four DO seniors did. Out of 230 total plastic surgery positions, DO seniors filled fewer than 2% of them. Neurosurgery: 243 MD seniors matched, 9 DO seniors, out of 280 positions. Vascular surgery: 92 MD seniors, 8 DO seniors. Interventional radiology: 49 MD seniors, 10 DO seniors.

These are not edge cases. These are the specialties that a significant number of medical students ultimately pursue, often after changing their minds during training. And 72% of medical students change their specialty preference after starting medical school.

You may enter thinking you want primary care and leave wanting neurosurgery. Or you could enter with plans for pediatric gastroenterology and end up chasing plastic surgery, the single most competitive specialty in medicine over the last decade.

If you’re a DO student, that door isn’t closed. But it is significantly narrower, and getting through it requires being an exceptional candidate by every measurable standard.

The specialties where DO students are well represented tell a different story. In 2026, DO seniors matched into family medicine at 1,403 positions, emergency medicine at 1,119, psychiatry at 566, and physical medicine and rehabilitation at 103, filling 40.7% of available PM&R spots.

These are accessible, rewarding fields. But the point isn’t which specialties are good or bad. The point is that choosing DO limits your options in ways that aren’t visible until you’re already in medical school, and by then it’s too late to change course.

How to Choose Between MD and DO

While the data has already made a strong case, it doesn’t make decisions. You do. So let’s be direct about how to think through this.

The single most important thing to understand when choosing between MD and DO is optionality. Medical school will change you. The specialty you want today is probably not the specialty you’ll want in two or three years. That’s not speculation. As we just covered, according to AAMC data, 72% of students entering medicine change their specialty preference or were never certain in the first place. You’re likely to be one of them.

This means the question isn’t just “what do I want to be?” It’s “which path keeps the most doors open while I figure that out?” 

Every single year, match data shows that earning an MD keeps more doors open. More research opportunities, stronger clinical training at academic medical centers, wider recognition for competitive specialties, and no additional board exam burden if you decide to chase one. You aren’t choosing between two equal paths and picking based on philosophy. You’re choosing between a path with more options and a path with fewer.

None of this means DO is a bad choice in every situation. If you only have DO acceptances and your goal is primary care, family medicine, emergency medicine, or psychiatry, going to a DO school and becoming a doctor is the right call. A DO degree with a clear specialty direction and a strong application beats waiting another cycle with no guarantee of a different outcome.

But if you’re applying to both MD and DO and earn an acceptance to both, go MD every time. And if you’re deciding which schools to apply to, apply to both, but aim as high as you can on the MD side. The best program you can get into, whether it’s a top 15 school or a solid mid-tier program, will serve you better than a DO school, because you don’t yet know which version of yourself will be walking out four years from now.

Maintaining optionality is the most important strategic decision you’ll make before you even set foot in a lecture hall.

MD vs DO Misconceptions

1 | MD and DOs Have the Same Residency Opportunities

This is the misconception that does the most damage because it sounds reasonable on the surface. Both MDs and DOs are fully licensed physicians. Both can practice in any specialty. While this is technically true, the match data shows that matching into any specialty is very different from practicing in one. 

The gap is most visible in competitive specialties, but it extends beyond residency. DOs have a harder time practicing medicine outside the US. Many countries don’t recognize the DO degree the same way they recognize the MD, which limits international career options. 

Fellowship opportunities at top academic institutions can also be harder to access as a DO, partly because of perceptions of the degree and partly because the research infrastructure at most DO programs is weaker than that at MD programs.

The degree matters, and pretending otherwise doesn’t help anyone.

2 | MDs Make Better Doctors

While this one goes the other direction, it’s equally wrong. 

The degree doesn’t determine how good a doctor you are. You can have an MD and be a terrible physician. You can have a DO and be an exceptional one. What makes a great doctor has nothing to do with which letters follow your name and everything to do with your clinical judgment, your commitment to your patients, and how seriously you take your ongoing education.

This article is not to say that DO physicians are inferior. It’s to say that the DO path comes with structural disadvantages that affect your training opportunities and specialty options. Those are system-level realities, not a reflection of individual ability. There are many great DO doctors. The degree is the starting point, but what you do with it is up to you.

3 | You Have to Choose DO if You Have Lower Grades

No, you don’t have to go the osteopathic route if you have lower grades. This is one of the most consequential misconceptions in the premed space because it pushes students toward a decision they may regret before they’ve explored every alternative.

If your grades aren’t where they need to be, you have options. Take a gap year, or two. Build more research experience. Strengthen your extracurriculars. Develop leadership credentials. Retake courses where you underperformed. Improve your MCAT score. These are all legitimate paths to becoming a more competitive MD applicant.

Medicine is a long road, regardless of which direction you take. You’re looking at four years of medical school, three to seven years of residency, and potentially one to two years of fellowship after that. In that context, an extra year to build a stronger application is basically a rounding error. If MD is what you want, another year spent becoming a better candidate is worth it.

4 | Caribbean Schools Are Another Viable Option

This is an issue of easy now, hard later. 

Getting into a Caribbean school is significantly easier than getting into a US medical school, and these schools accept students year-round. Not only can this feel like a lifeline, but it’s also a lifeline on a white sand beach underneath clear blue skies and sunshine. 

But the reality is more complicated than “earn your MD while also having fun in the sun!” 

In 2026, 93.2% of DO seniors matched into US residency programs. For US IMGs, meaning graduates of Caribbean and other international medical schools, the figure was 70.0%. And even that number deserves context. It reflects attainment rather than strict NRMP match rates, meaning it includes positions filled through SOAP and other last-minute routes after the main match closes. Most Caribbean schools don’t publish their match data at all, which should tell you something.

Even if you do match, competitive specialties are largely out of reach. Dermatology, plastic surgery, orthopedic surgery, and others like them are effectively closed doors for Caribbean graduates. Even in less competitive specialties, you’ll need to significantly outperform US graduates on Step 2 CK just to compensate for where you trained.

There’s also a financial trap that most students don’t see coming. At many Caribbean schools, failing a course doesn’t mean repeating that course. It means repeating the entire semester and paying full tuition again. The costs compound quickly.

This is why the cons far outweigh the pros of attending Caribbean medical schools. 

5 | Only Osteopathic Doctors Treat the Whole Body

This framing is a marketing position, not a medical reality. MDs consider how the body’s systems interconnect and influence each other. Prevention, health optimization, and patient-centered care are all central to allopathic medicine. The idea that MDs only get involved after a disease reveals itself is a myth.

The DO curriculum adds OMM on top of the same foundational medical training that MD students receive. That distinction in how the degrees are structured is meaningful. It’s not evidence that osteopathic physicians have a monopoly on holistic thinking. Plenty of MDs practice in ways that are deeply attentive to the whole patient. 

The label doesn’t determine the approach.

6 | Higher Loan and Debt Burden

Most people assume that because MD programs are more competitive and often more prestigious, they must cost more. But it’s the opposite that tends to be true.

Many DO programs are private institutions with less state funding and subsidization than their MD counterparts. They also tend to have smaller endowments, fewer scholarships, and less robust alumni networks to support students financially. The result is that DO students often graduate with significantly more student loan debt than their MD counterparts.

The financial burden doesn’t stop at tuition. DO students frequently have to travel to rotation sites, sometimes to institutions in entirely different states, because their home program doesn’t host the full range of clinical training. Transportation and housing costs for multi-month rotations add up on top of already higher tuition. It’s a cost that most students don’t factor in when they’re making the decision, and by the time they do, they’re already enrolled.

DO vs MD: Which Should You Choose? 

The answer comes down to two things: your options and your goals.

If you have an MD acceptance, take it. If you have both an MD and a DO acceptance, take the MD. The data is consistent and clear on this. MD programs offer stronger clinical training, better research infrastructure, wider recognition in competitive specialties, and more flexibility as your interests evolve during medical school.

If you only have DO acceptances, the decision gets more nuanced. Think honestly about your specialty goals. If you’re drawn to primary care, family medicine, emergency medicine, psychiatry, or PM&R, a DO degree will serve you well. These are fields where DO graduates match at strong rates and build excellent careers. Go to school, become a doctor, and don’t look back.

But if you’re drawn to dermatology, plastic surgery, neurosurgery, orthopedic surgery, ENT, or another competitive specialty, a DO acceptance is not the same as a path to those specialties. You need to be honest with yourself about whether a gap year to strengthen your MD application is the smarter long-term move.

And if you don’t know what specialty you want, which statistically describes the vast majority of students out there, the answer is straightforward. Do everything you can to get into the strongest MD program possible. Protect your options. You will almost certainly change your mind during medical school, and the doors available to you when that happens will depend heavily on where you trained and what degree you hold.

The goal isn’t to pick the right degree. The goal is to become the best physician you can be, in the specialty you love, with as many options available to you as possible. 

MD vs DO FAQ

Is a DO degree as good as an MD degree? 

Both are fully licensed medical degrees that allow you to practice medicine in any specialty across all 50 states. So in that sense, yes. 

But the data show meaningful differences in residency match outcomes, particularly in competitive specialties, research opportunities, and international practice recognition. The degrees are not identical in what they open up for you.

Can a DO become a surgeon? 

Yes. DOs match into general surgery, orthopedic surgery, and other surgical specialties every year. 

That said, the match rates in the most competitive surgical subspecialties, such as plastic surgery and neurosurgery, are significantly lower for DO graduates than for MD graduates.

It’s not impossible, but it’s also not very likely.

Do DOs make less money than MDs? 

Physician salary is determined primarily by specialty, not by degree type. A DO in a high-paying specialty will out-earn an MD in a lower-paying one. 

That said, because DOs are less likely to match into the highest-compensated specialties, there is a population-level salary gap that reflects specialty distribution rather than the degree itself.

Should I apply to both MD and DO schools? 

Only if you have seriously weighed the downsides of going DO and are still confident that you would prefer to go to a DO school if MD were not an option. If you’re only applying to DO as a last resort backup plan, you’re far better off applying to a broader list of MD schools. Many students apply to too few schools, which results in no MD acceptances.

A broad, strategic list of over 30 schools vastly increases your chances of an MD acceptance. The Med School Chance Predictor will help you craft a dynamic list of ideal schools for you in minutes.

There is no strategic reason to add DO schools to your list if you have a realistic shot at allopathic programs. 

If your stats fall below the MD threshold, applying to both makes sense to keep your options open. If you receive both MD and DO acceptances, take the MD every time.

USMLE vs COMLEX: Can a DO Take Both?

DO students are required to take the COMLEX but not the USMLE. Many choose to take both, particularly those applying to competitive specialties or programs that prefer or require USMLE scores. Taking only COMLEX limits your options. If you have competitive ambitions, plan on sitting for both.

Is it harder to get into MD or DO schools? 

MD programs have higher GPA and MCAT requirements. 

The average MD matriculant enters with a 3.81 GPA and a 512.1 MCAT score. The average DO matriculant enters with a 3.60 GPA and a 502.97 MCAT score. 

That gap translates into a meaningful difference in the competitiveness of the applicant pool, and it’s why students with stronger stats should aim for MD programs first.

Can a DO practice internationally? 

It depends on the country. The MD degree is more widely recognized globally. DOs can face additional licensing hurdles or outright restrictions when trying to practice outside the United States, which is worth factoring in if international practice is part of your long-term plan.

What is OMM, and do DOs actually use it? 

OMM, or Osteopathic Manipulative Medicine, is a set of hands-on techniques that DO students spend 300 to 500 hours learning during medical school. 

Although the overwhelming majority of practicing DOs do not use OMM with their patients after residency, it is part of the DO curriculum regardless of whether you intend to use it.
