When applying to medical school, letters of recommendation (LoRs) can make or break your application. A strong letter could be the tipping point that moves your application from the pile of ‘maybe’ to the interview shortlist.
This guide will walk you through everything you need to know about securing powerful letters of recommendation that will give your application the edge it needs.
What Is a Medical School Letter of Recommendation?
These letters, often referred to as letters of evaluation, offer admissions committees a glimpse of your character, work ethic, and potential beyond the numbers on your transcript.
Most letters come from science professors, research mentors, or other faculty members who have worked with you in an academic program. Some applicants also include a clinical letter from physicians or supervisors who observed their work with patients.
A well-crafted letter of recommendation usually includes the following sections.
| Section | Purpose |
|---|---|
| Introduction | Establishes the writer’s relationship with the applicant |
| Academic Evaluation | Describes the applicant’s performance in science courses or academic programs |
| Personal Qualities | Highlights professionalism, teamwork, and communication skills |
| Examples | Provides specific examples of academic, research, or clinical work |
| Final Endorsement | Recommends the applicant’s medical school admission |
Who Should Write Your Medical School Letters?
Your letter writers should know your work well and be able to describe your abilities in detail.
Common letter writers you may choose are:
| Type of Writer | Role |
|---|---|
| Science professors | Evaluate your academic ability in science disciplines |
| Research mentor | Discuss your research work and previous lab contributions |
| Principal investigators | Evaluate your research leadership and project work |
| Clinical supervisors | Describe patient care experience |
| Pre-health advisor | Provide guidance and institutional context |
Approach your potential writers and ask them directly if they feel they can speak to the strengths and characteristics that make you an excellent candidate for med school. Have your resume, personal statement, and any other relevant materials ready to share with them. Don’t just tell your recommenders what you’ve done. Show them your enthusiasm for medicine. Let them see your passion so they can reflect that energy in the letter.
Most applicants secure letters from science professors who have taught them in demanding courses like biology, chemistry, or physics, as these professors can speak to your academic strengths and ability to thrive in rigorous coursework. Applicants with research experience often turn to research supervisors or principal investigators who can attest to their contributions, problem-solving skills, and dedication in the lab. Clinical letters from physicians or supervisors who’ve observed your work in hospitals or clinics demonstrate your hands-on experience and ability to engage directly with patients.
Note: Family members cannot write your letters. Admissions committees expect recommendations from professors, supervisors, or other professional mentors who can offer an objective and informed evaluation of your qualifications.
How Many Letters of Recommendation Do You Need for Med School?
Most medical schools ask for 3 to 5 letters of recommendation, but the exact number depends on the school. In most cases, you will need two letters from science professors (like biology or chemistry) and one letter from a non-science professor. Some schools also accept extra letters from a research mentor, a doctor, or a work supervisor.
The typical structure looks like this:
| Letter Type | Typical Requirement |
|---|---|
| Science professor letters | Two letters |
| Non-science professor | One letter |
| Additional letters | Optional (depending on the school) |
Many schools request two science letters from science faculty who taught you in core science courses. These letters confirm your ability to succeed in demanding science coursework. A non-science letter usually comes from a professor in a humanities or social science course. This letter evaluates writing ability, reasoning, and communication. Some applicants also submit additional letters written by research mentors or clinical supervisors.
Typical letter combinations include:
- Two science letters + one non-science letter
- Two science professor letters + one clinical letter
- One committee letter
- Two letters from science faculty + research mentor letter
Some schools accept additional letters. As an applicant, you should review the requirements of specific medical schools before submitting extra letters. Just take note that submitting too many letters can weaken your application if the letters repeat the same information. Admissions committees prefer fewer letters that provide detailed evaluations.
Medical School Letters of Recommendation Types and What They Mean
Medical schools accept several different letter formats. Your college’s policies determine which formats will be available to you.
Committee Letter
A committee letter, also called a composite letter, is written by a pre-med or pre-health committee at your college. It combines feedback from professors, advisors, and even your extracurricular or volunteer experiences. The committee reviews your grades, activities, and interviews before writing the letter, which may include letters from several professors. Many medical schools prefer a committee letter or a mix of individual letters. If your school offers this option, it's a good idea to use it because it gives a full picture of your readiness for medical school.
Letter Packet
A letter packet is a group of letters collected by your school’s advising office or institution's career center. The packet includes academic letters, research letters, and other recommendations submitted together. The advising office compiles the packet and sends it to application services. This allows the admissions committee to review several letters at once.
Individual Letters
An individual letter is written by one person, like a professor or mentor.
Common individual letters include:
- Science professor letters
- Non-science professor letters
- Research mentor letters
- Clinical letters
Individual letters work well for applicants whose schools do not offer a pre-med committee letter. If an individual letter is already part of a Committee Letter or Letter Packet, do not include it again as a separate submission.
How to Request Letters of Recommendation
Knowing how to request letters can improve the quality of the recommendations you receive.
When to Request Letters
Request your letters of recommendation at least 3 to 4 months before submitting your medical school application. If you’re applying in May or June, when applications open, request your letters in January. This allows your recommenders ample time to craft a thoughtful and detailed letter. Giving them this lead time not only ensures they can write high-quality recommendations but also provides room for any necessary revisions or adjustments. Planning ahead is key to securing strong letters that truly reflect your strengths and readiness for medical school.
What to Provide Letter Writers
When requesting letters, provide materials that help writers describe your achievements.
Typical materials include:
- Resume or CV
- Personal statement
- Transcript
- Research summary
- List of achievements, awards, and honors
- Instructions for submitting (including letterhead and deadlines)
- Consent forms (if needed by the school)
- Important details about the school you’re applying to
- Any other documents that are required or helpful
These materials help writers prepare a strong letter with detailed examples.
How to Submit Letters Through AMCAS
Many U.S. medical schools use the AMCAS letter service to collect and distribute letters. It allows applicants to upload letter information and track submissions from their writers.
Creating a Letter Entry
To submit letters, you must create a letter entry in the AMCAS application.
The process usually follows these steps:
- Add your letter writers to the system
- Create one letter entry for each writer
- Send the request form to the writer
- Writers upload the letter through the AMCAS portal
Each writer submits letters directly to AMCAS using the provided request form.
Designating Letters to Schools
After uploading letters, you can designate letters to specific programs. The system allows you to send different letters to different schools.
The AMCAS system also allows you to:
- Store letters for future use
- Access existing letters from previous cycles
- Submit additional letters if permitted
Applicants should confirm the requirements of each specific school before submitting extra letters.

What Makes a Strong Medical School Letter?
Admissions committees review numerous recommendation letters, so a strong letter must stand out by providing specific examples and a thorough evaluation of your abilities. A compelling letter is detailed, highlighting key qualities that make you a strong candidate for medical school.
A great letter often includes:
- Direct observation of your work
- Clear evaluation of your academic ability
- Concrete examples of teamwork and leadership
- Comparisons with other students to showcase your strengths
The best letters also demonstrate that the writer knows you well. A letter from a professor who supervised your research or taught your class carries more weight than a generic letter from someone unfamiliar with your work. Committee letters and letter packets that provide a detailed, consistent account of your qualifications are particularly valuable.
Common Mistakes Applicants Make
Asking Professors Who Do Not Remember Your Work
One of the most common mistakes applicants make is asking professors who don’t remember their work to write their medical school letters of recommendation. Admissions committees value letters from letter writers who can provide detailed insights into your abilities. Asking someone who doesn’t recall your performance in class or research work will result in a generic, unhelpful letter.
Submitting Too Many Additional Letters
It may seem like submitting more letters of recommendation gives you an advantage, but submitting additional letters can backfire. Most medical schools require three to four letters, two science professor letters and one non-science letter, though some applicants may submit a clinical letter or research mentor letter. Submitting more than the required number of letters, especially when they don’t add any new insights, can overwhelm the admissions committee. It’s important to designate the correct letters through the AMCAS letter service and make sure all the letters you submit are relevant and add unique value to your application.
Missing School-Specific Requirements
Each medical school has specific requirements when it comes to letters of recommendation. Some may ask for a committee letter, while others might require individual letters or a combination of both. Missing these specific requirements can result in a delay or a rejected application. Always double-check each school’s requirements and ensure you’re submitting the appropriate type of letter, whether it’s a pre-medical committee letter or individual letters from professors, mentors, or supervisors. For some specific medical schools, using a composite letter from a pre-health advisor or institution’s career center is strongly advised.
Waiting Too Long to Request Letters
Waiting too long to request your letters can cause unnecessary stress and potential delays. Requesting letters well in advance, at least 3 to 4 months before your medical school application deadline, gives your letter writers ample time to craft strong, personalized letters. This timeline is especially important if you’re requesting letters from busy science faculty or research supervisors who may have tight schedules. When requesting letters, be clear about your deadlines and give your recommenders plenty of time to write a letter that reflects your strengths.
Repeating the Same Information in Multiple Letters
Each letter of recommendation should offer new insight into your abilities and character. It’s a mistake to submit letters that repeat the same information or lack new examples of your accomplishments. If you submit multiple letters from the same type of letter writer, such as science professors or clinical supervisors, make sure each one highlights different aspects of your qualifications. A strong letter of recommendation should provide unique perspectives, whether it’s through your work in class, research, leadership, or clinical settings. When you submit individual letters or a letter packet, ensure each letter assembles a well-rounded view of your abilities, rather than simply rehashing what’s already covered in your personal statement or other application materials.
Tips for Non-Traditional Applicants
If you are a non-traditional applicant, you may often face unique challenges when it comes to obtaining strong medical school letters of recommendation. However, this doesn’t mean you can’t still submit outstanding letters that demonstrate your readiness for medical school.
Letters from Research Supervisors
Your research mentors and principal investigators can be invaluable sources for letters of recommendation. Research supervisors are often familiar with your critical thinking, problem-solving skills, and ability to handle complex academic work. A letter from a research supervisor demonstrates your experience in scientific inquiry, which is crucial for success in medical school, especially if your background is in a science discipline.
Letters from Physicians Who Supervised Clinical Work
Another strong option is obtaining a clinical letter from physicians who have supervised your clinical work. This letter showcases your hands-on experience and your ability to interact with patients, both of which are vital skills for success in medical school. Admissions committees place great importance on clinical exposure, so a well-written clinical letter provides a clear picture of your ability to thrive in a healthcare setting.
Letters from Graduate Program Professors
You may also consider reaching out to professors from any graduate programs they have participated in. Graduate program professors can speak to your ability to handle advanced coursework and your readiness for the academic demands of medical school. These letters are especially helpful if your previous studies were in fields like public health, biomedical sciences, or even non-science disciplines.
Letters from Work Supervisors in Healthcare Settings
Work supervisors from healthcare settings also make excellent letter writers for non-traditional applicants. Supervisors who have directly observed your work in healthcare roles can speak to your professionalism, communication skills, and commitment to patient care. These qualities are essential for medical school, and a letter from someone who has worked closely with you in a healthcare setting can offer concrete examples of your readiness to succeed in a clinical environment.
The Bottom Line
Strong medical school letters of recommendation are essential for showcasing your qualifications and readiness for the challenges ahead. To maximize the impact of these letters, it’s vital to build strong relationships with faculty early on and give your recommenders time before your application deadline. Utilize the AMCAS letter service for a streamlined submission process, and be sure to follow the specific requirements of each school. A thoughtful, personalized letter from someone familiar with your academic work, clinical experiences, or research will significantly strengthen your application, providing admissions committees with an in-depth, authentic view of your potential for success in medical school.
