Medical School Requirements: Letters of Recommendation

Medical School Requirements: Who Should Write Your Letters of Recommendation?

Securing letters of recommendation for medical school is a key part of assembling your AMCAS® application. These reference letters are important because they have the potential to impress admissions committees by showing them your diverse attributes from an external perspective. To ensure you’re being presented in the best light, you’ll want to submit medical school recommendations from accomplished individuals who can paint a flattering picture of you through vivid descriptions, concrete examples, and sincere praise. In this guide, we’ll help you determine who you should approach to write you a letter of recommendation for medical school.

Requirements for Medical School Letters of Recommendation

Each medical school has its own set of standards and formats for securing letters, so you’ll want to research the specific schools you’re interested in attending. If you’re applying to U.S. allopathic (MD) medical schools, visit the AMCAS website and check out the latest Medical School Admissions Requirements™ (MSAR®) guide. If you’re applying to osteopathic (DO) medical programs, you should visit the AACOM website to learn more about admissions requirements for these schools. Alternatively, visit the admissions requirements section of individual school websites for their letter of recommendation requirement.  

Factors to consider when requesting letters of recommendation for med school: 

  • Deadlines for submitting your letters of recommendation 
  • The number of letters required (three is the average for most schools, but requirements can vary)
  • Types of recommenders (see more below)

How to Choose Recommendation Writers for Medical School

Learn how to choose the right people to write letters of recommendation for your medical school applications. Keep in mind that some medical schools will require specific types of recommenders (for example, science professors from whom you took an in-person class and received a letter grade). Whoever you choose to ask, don’t wait until the last minute. Give your recommender plenty of time to write you a glowing letter.

Who should write medical school letters of recommendation?

Listed below are the individuals you should contact to write your medical school letters of recommendation.

  • Science Professors

    You’ll want at least two recommenders from a pre-medical science course you’ve successfully completed, such as biology or organic chemistry, to speak to your hard science credentials. A teaching assistant should not write the letter, though TAs are welcome to co-sign or otherwise contribute their thoughts to the professor writing your letter. If you don’t have strong relationships with any of your professors, start visiting them during office hours to build rapport.


  • Non-Science Professors

    Reach out to a humanities or social sciences professor (past or present) as well. They can often offer perspectives on different sides of you than your science professors have seen.


  • Physicians

    Find someone who knows you personally, ideally someone you’ve worked with or shadowed outside of class. This should be able to address how well you interact with patients, how comfortable you are in clinical settings, and how curious and committed you are to medicine.


  • Pre-Med Advising Committee

    If your college has a pre-professional advising committee, pre-med office, or similar body at the institution, the committee might write you a Committee Letter, after requesting information from you (e.g., autobiography, resume), interviewing you, and reviewing recommendation letters you’ll have your writers submit to them. Other schools might assemble a Letter Packet containing a cover letter and your individual letters of recommendation.


  • Research Directors or Principal Investigators (PI)

    If you have significant research experience, asking a research supervisor or PI would be a great way to highlight your analytical ability and experience with the scientific method–something you’ll use a lot in medicine!


  • Representatives From Volunteer Programs

    If you have significant volunteer experience, medically-related or not, having someone speak about your commitment to serving others can be very powerful, as it’s a core characteristic medical schools seek in applicants.


  • Graduate Program Directors

    If you are a graduate student or have completed a graduate degree, your program director should be in a good position to speak about your academic ability and interpersonal qualities, which are very important to med schools!


If you are reapplying to medical school, you must include new or updated letters of recommendation accounting for your past year’s activities, credentials, and successes.

Characteristics to Look for in Medical School Recommenders 

When choosing recommenders to help you meet your med school requirements, it’s important to note that your letter writers’ credentials of don’t carry more weight than what they write about you. In other words, just because someone is a respected authority in a specific field doesn’t necessarily make them the right person to pen one of your letters of recommendation.

It’s far more important that recommenders know you as an individual and can speak to your qualities and qualifications. Along the same lines, you want to avoid the dreaded “form letter” recommendation because it says nothing unique about your personal attributes versus any other applicant’s. 

Your goal is to identify medical school recommenders who are knowledgeable about three things:

  1. Your unique characteristics and credentials
  2. The demands of medical school
  3. What makes you qualified for medical school

Pre-Med Competencies

Ideally, each letter of recommendation will highlight two or three of your many admirable qualities and experiences so that when your letters are viewed as a whole, med school admissions committees will have a vivid and well-rounded impression of your character.

The AAMC & admissions committees have identified the following standard qualities people in the medical profession should have:

Professional Competencies 

  • Commitment to Learning and Growth
  • Cultural Awareness
  • Cultural Humility
  • Empathy and Compassion
  • Ethical Responsibility to Self and Others
  • Interpersonal Skills
  • Oral Communication
  • Reliability and Dependability
  • Resilience and Adaptability
  • Service Orientation
  • Teamwork and Collaboration

Science Competencies

  • Human Behavior
  • Living Systems

Thinking and Reasoning Competencies

  • Critical Thinking
  • Quantitative Reasoning
  • Scientific Inquiry
  • Written Communication

Looking at the list above, which of these qualities do you possess? Who are the people in your life who can attest to them? Answering these questions will go a long way toward helping you identify and choose the people who are best suited to write your letters of recommendation for medical school.
