There is no national answer to how many clinical hours for med school you need. The AAMC and AACOM do not publish a universal minimum, so you should focus on meaningful, sustained experience and check the expectations of each medical school on your list.
Schools define and evaluate clinical exposure differently. Some publish school-specific benchmarks, while others emphasize direct patient contact, the quality of your involvement or what you learned. Shadowing, paid clinical work, volunteering and other health care activities may also belong in different application categories.
Clinical Hours for Medical School at a Glance
- Neither the AAMC nor AACOM sets a national minimum number of clinical hours for medical school.
- Published hour figures from individual schools apply only to those schools and measure different combinations of experience.
- What you did, how long you stayed involved and how clearly you describe what you learned can matter more than accumulating a particular total.
- AMCAS and AACOMAS record experiences differently, so keep accurate dates, hours and supervisor information as you participate.
Is There a Minimum Number of Clinical Hours for Medical School?
Neither the AAMC nor AACOM sets one minimum number of clinical hours for medical school. In a 2016 AAMC Committee on Admissions survey, medical schools said what applicants gained from clinical experience mattered more than their number of hours. The survey went to admissions contacts at AAMC member medical schools, and 43% of member schools responded.
Among those responding schools, 73% highly recommended or required experience that allowed applicants to observe and learn about clinical practice. In addition, 87% said applicants without clinical experience could be disadvantaged. These findings show the importance of exposure to clinical practice, but they do not establish a national hour requirement or describe every medical school.
The AMCAS Work and Activities instructions also tell applicants that schools want quality rather than quantity. Although AMCAS permits up to 15 Work and Activities entries, it advises applicants to include only significant experiences. A long activity record is therefore not a substitute for choosing experiences you can discuss with clarity and substance.
What Counts as Clinical Experience?
What counts as clinical experience depends on what you actually did and how the school or application service classifies it. Medical schools use terms including clinical experience, clinical exposure, patient care interaction, physician shadowing and clinical observation. Similar language does not always mean that schools evaluate every activity in the same way.
The 2027 AMCAS Application Workbook includes separate experience types for Community Service/Volunteer (Medical/Clinical), Paid Employment (Medical/Clinical) and Physician Shadowing/Clinical Observation. You select the category that fits each activity because, as the AMCAS Applicant Guide explains, experience types are self-identified. The activity title alone does not make that choice for you.
How Is Shadowing Different From Patient-Facing Experience?
Shadowing is observation rather than the practice of medicine. The AAMC shadowing guidelines adopted in 2013 say a pre-medical student watches clinical work and should never do anything considered the practice of medicine. Volunteering, by contrast, is unpaid help in a health care setting that, depending on the setting, might include filing paperwork, answering phones or playing a game with a child.
This distinction is why you should evaluate your duties instead of assuming that every hospital activity is hands-on clinical experience. Read more about shadowing vs clinical experience, then plan how many shadowing hours medical schools expect as a separate question.
How Are Common Clinical Roles Classified?
Common routes to clinical exposure include hospice volunteering, certified nursing assistant work, volunteer EMT service, scribing and caring for an ill family member. The AAMC Aspiring Docs alternatives page identifies these options, while the 2016 admissions survey also lists clinical volunteering, EMT, scribe, clinical research, CNA and medical assistant work as possible alternatives when an applicant cannot secure shadowing.
Job duties still matter. AAMC Aspiring Docs describes a hospital scribe as a role that is usually paid and based in an emergency department, where the scribe helps a physician gather information and document care. Its description of CNA preparation says training programs can last four to sixteen weeks and may be available through community colleges, vocational schools or the Red Cross.
Georgetown illustrates why the setting alone is not decisive. Its MD application guide says activities such as reading to children, stocking shelves or transporting patients in a clinic waiting room can be good volunteer service without being hands-on clinical experience.
Compare your real responsibilities with more ways to get clinical experience, or review what is involved in becoming a medical scribe.
Clinical Hour Figures Medical Schools Publish
Individual medical schools publish different expectations, definitions and reference points. The figures below apply only to the named school and application cycle. They measure different combinations of clinical work, volunteering, shadowing or other exposure, so they cannot be combined into a national standard.
University of Utah Spencer Fox Eccles School of Medicine
For the 2026-2027 cycle, the University of Utah admissions requirements list 800 hours as the average clinical experience of competitive MD applicants. Utah expressly identifies this as a reference rather than a minimum. The school defines clinical experiences as activities in a clinical setting that demonstrate commitment to medicine and patient care, familiarity with a physician’s typical day or interaction with varied specialties, settings and patient populations.
Georgetown University School of Medicine
For the 2026-2027 cycle, Georgetown University School of Medicine says a highly competitive applicant presents at least 200 hours of substantive, longitudinal clinical experience. Its examples include shadowing, medical mission trips, scribing and community EMS, with most of the experience taking place in the United States. This is Georgetown’s description of a highly competitive applicant, not a requirement that applies to every medical school.
Northwestern University Feinberg School of Medicine
On its requirements page for 2027 matriculation, Feinberg School of Medicine says it does not require a set amount of research or clinical experience. It reports an average of 200 to 300 hours of combined volunteer and clinical experience, with a wide overall range. Because that figure combines categories, it should not be treated as a clinical-hours minimum.
Loma Linda University School of Medicine
For the 2027 application cycle, Loma Linda University School of Medicine requires physician shadowing and direct patient care exposure. Its admissions page does not state an hour total, which reinforces the need to distinguish a required type of experience from a numerical requirement.
University of New Mexico School of Medicine
The University of New Mexico School of Medicine expects clinical experiences involving direct patient contact. Its Committee on Admissions reviews each type of experience and evaluates both the quality of the work and how the applicant explains it.
University of Mississippi Medical Center School of Medicine
The University of Mississippi Medical Center School of Medicine strongly recommends direct exposure to patients and patient care. Its file review considers both the length of time spent on each activity and its quality, and the page gives no hour total for patient care exposure.
Clinical Hours for DO Schools
AACOM’s guidance for applicants does not give a number of clinical hours for osteopathic medical schools. Its admissions requirements guidance says osteopathic schools look for applicants who have some clinical experience, a record of community service and experience shadowing an osteopathic physician, among other qualities.
The AACOM pre-med timeline advises students to begin gaining exposure through shadowing, volunteering, internships or employment such as CNA and EMT work. It also recommends keeping a record of these activities. If you are comparing degree paths as you plan your experience, IMA’s MD vs DO guide provides additional context.
AACOMAS uses Healthcare Experience for paid or unpaid work in a health field when you are not directly responsible for patient care but may interact with patients. Its examples include taking vital signs, working as a scribe, medical assisting and some CNA positions, depending on the job description.
The AACOMAS Applicant Help Center says the service has no category preference and cannot guarantee that each program will interpret an activity as you do. How AACOMAS counts those hours is covered in the reporting section below.
How to Decide How Many Clinical Hours You Need
Decide how many hours you need by examining the depth, duration and relevance of your experience alongside each target school’s policies. AAMC Aspiring Docs says admissions officers value depth, longitudinal commitment and your ability to explain how medical exposure informed your motivation for medicine. That makes a sustained activity you can discuss meaningfully more useful than pursuing an unsupported national target.
The AAMC also identifies empathy, service orientation, ethical responsibility and awareness of a physician’s work as qualities admissions committees seek. Its premed competencies define Service Orientation as commitment to something larger than yourself through service that meets community needs. Empathy and Compassion involve recognizing other people’s experiences and wanting to help alleviate distress. You can use these ideas when assessing which clinical experiences admissions committees value.
Individual admissions leaders also offer useful perspectives, but their comments are not national rules. In an AAMC article featuring admissions officers, University of Illinois College of Medicine admissions dean Jorge A. Girotti said it makes sense to wait until you have at least one year of clinical experiences before applying. In the same article, Wake Forest School of Medicine admissions dean David D. Grier encouraged applicants to connect their experiences into a story rather than presenting a checklist of activities.
Review the admissions page for every school you are considering. If an activity’s value or classification remains unclear, AAMC advises contacting the school to confirm that it meets the school’s criteria.
How to Report Clinical Hours on AMCAS and AACOMAS
Report clinical hours using the format required by the application service, and keep records detailed enough to support each entry. In the AMCAS application, each Work and Activities entry includes its dates and total hours, a contact person who may verify that the activity occurred and a description of up to 700 characters, according to the AMCAS Applicant Guide.
The 2027 Work and Activities Guide for Applicants allows three additional date ranges for a repeated activity. You may designate up to three activities as most meaningful and receive 1,325 additional characters for each. AMCAS separates Completed hours from Anticipated hours. For the 2027 cycle, an anticipated activity begins during the submission month or later and must end by August 2027.
AACOMAS asks for average weekly hours during the experience rather than the AMCAS total-hours format. It also prohibits counting the same hours under multiple types. If one position covers two types, divide the hours between them instead of reporting the full schedule twice.
Maintain a contemporaneous log containing your dates, hours, activity details and supervisor information. A consistent system for tracking clinical and volunteer hours can make it easier to prepare accurate entries and separate completed work from future plans.
Clinical Experience Abroad
Clinical experience abroad can contribute to your understanding of medicine, but you must remain within the activities permitted by your training and role. In the 2016 AAMC clinical experiences survey, 45% to 50% of responding schools considered applicant involvement in invasive procedures abroad, such as vaccinations, suturing, pulling teeth or delivering a baby, harmful to or of no value to the application. Between 35% and 40% held that concern even when a health professional supervised the applicant.
Before choosing an international opportunity, compare clinical experience abroad vs in the U.S. and confirm exactly what participants may observe or do. IMA’s pre-med internships are one option to review with those questions in mind. Participation in an international program does not create an admissions guarantee or override an individual school’s expectations.
Build a Clinical Experience Plan That Fits Your Schools
Start with the admissions policies for the schools you may apply to, then choose experiences that give you sustained exposure and something meaningful to discuss. Keep accurate records as you participate, review how each application service classifies your work and avoid treating another school’s benchmark as your personal requirement.
When you are ready to present what you learned, prepare for talking about clinical experience in interviews. If you want individualized help assessing your application plan, you can also review IMA’s medical school admissions consulting.
Frequently Asked Questions
How Many Clinical Hours Do You Need for Medical School?
There is no national hour requirement for medical school. The AAMC emphasizes what you gain from clinical experience, including its depth and duration, rather than prescribing one total. Check each target school because individual institutions may publish their own expectations or reference points.
Do Medical Schools Require a Minimum Number of Clinical Hours?
Some schools require particular forms of clinical exposure, but neither the AAMC nor AACOM sets a universal minimum. School policies vary. Loma Linda, for example, requires direct patient care exposure and physician shadowing without publishing a number of hours.
Does Shadowing Count as Clinical Experience?
Shadowing is a form of clinical observation, but it is not hands-on patient care. AMCAS lists Physician Shadowing/Clinical Observation separately from paid and volunteer medical or clinical experience. AAMC guidelines also state that a shadowing student should never perform the practice of medicine.
Is Scribing Clinical Experience for Medical School?
Scribing can be classified as clinical or health care experience, depending on the application service and your actual duties. AAMC identifies scribing as an alternative form of clinical exposure, while AACOMAS includes scribing as an example of Healthcare Experience. Confirm how each target program evaluates the role.
How Many Clinical Hours Do DO Schools Want?
AACOM’s admissions requirements do not give an hour figure for DO schools. It says osteopathic medical schools look for some clinical experience, community service and experience shadowing an osteopathic physician. You should check each program’s requirements because schools may assess activities differently.
Can You List Anticipated Clinical Hours on AMCAS?
Yes. AMCAS records Completed and Anticipated hours separately. For the 2027 application cycle, anticipated experiences begin in the month you submit or later and must have an end date no later than August 2027.
Does Clinical Experience Abroad Count for Medical School?
An international experience may provide clinical exposure, but each school decides how it evaluates the activity. Stay within your training: in a 2016 AAMC survey, many responding schools viewed invasive procedures by applicants abroad as harmful or of no value to an application, even when supervised.
Is Volunteering at a Hospital Clinical Experience?
Hospital volunteering may be clinical, but the location alone does not determine the classification. Patient-facing responsibilities may differ from filing, answering phones, stocking shelves or other support work. Review your actual duties and ask target schools how they would evaluate the activity.
