Letters of Recommendation

Part of The Application. A letter is someone else's account of how you think, work, relate to people, and respond to responsibility. You cannot manufacture that account in the month before you apply. You can build the relationships that make a specific, credible letter possible — and you can make the request easier to fulfill.

Start with the school's requirements

There is no universal letter package. Schools vary in the number of letters they require, the types of writers they prefer, whether they accept a committee letter or packet, whether they require a physician or research letter, and whether letters must be on letterhead or submitted through a particular service.

Start with your school list. Make a small table with each school's required and recommended letters, committee-letter policy, submission method, deadline, and any special instructions. MSAR is useful for MD schools; DO applicants should check AACOM's Choose DO Explorer and each college's website. Requirements change, and a centralized service does not erase school-level differences.

For AMCAS, you can associate up to 10 letter entries, but that is a system capacity, not a recommendation that every school wants 10 letters. Each school decides what it wants to receive. A committee letter, letter packet, and individual letter each count as one AMCAS letter entry, even when a packet contains several documents.1

Choose knowledge first — but do not pretend influence is imaginary

The famous title is not the first question. A strong letter comes from someone who can describe you accurately because they have watched you do something over time.

A professor who saw you revise a difficult project, a supervisor who trusted you with a real responsibility, a research mentor who knows how you respond when an experiment fails, or a clinician who observed your judgment may be able to write more useful sentences than a department chair who remembers only your grade.

That does not mean the writer's role is irrelevant. Some schools do prefer particular faculty types, and a school may require a science faculty letter or committee letter. Satisfy those requirements first. Within the acceptable pool, choose the people who know your work and can speak about it with detail.

There is also a hidden-curriculum truth here: medicine is a small world. If two people know you equally well and can write equally specific, strong letters, their institutional position and relationships can become a legitimate tie-breaker. A department chair, established attending, research director, or faculty member with a real relationship to your top-choice school may carry more institutional credibility than a freshly minted attending who knows you just as well. Someone who trained at that school, works in its affiliated hospital, knows its admissions leadership, or can speak credibly about your field may be better positioned to understand where you fit.

That influence can take several forms. The writer may give your application more context, tell you how the institution actually evaluates applicants, make a professional introduction, or — if appropriate within the school's process — personally vouch for the work they have seen you do. A person who knows you and knows the institution can sometimes advocate more effectively than a person who knows only one of those things.

But keep the hierarchy straight. Do not choose a famous or connected person who cannot write a genuinely strong letter. Do not assume an alumnus has special power. Do not ask for a back-channel intervention or treat a phone call as an entitlement. A letter should stand on its own, and admissions offices may have rules about outside contact, especially after a decision or on a waitlist. The practical question is: among writers who know me well enough to be specific, who also has relevant credibility or a real connection to the places and work I am pursuing?

For first-generation, low-income, nontraditional, and working students, relationships may not form through the usual campus shortcuts. You may not have family friends who are physicians or professors who invite students into their networks. That is not a deficit in your character. It means you may need to build the relationship deliberately: attend office hours, ask thoughtful questions, return for feedback, contribute reliably, and let someone see your work across more than one interaction.

Ask for a strong letter

Ask in a conversation when possible, not in a vague email sent at midnight. You can say:

I am applying to medical school, and I have valued the work we have done together. Would you feel comfortable writing me a strong, specific letter of recommendation?

The word strong gives a hesitant writer a way to decline. That is useful information, not an insult. A polite no now is much better than a generic or lukewarm letter arriving after your application is already moving.

Ask early enough that the writer can think. Six to eight weeks is a reasonable minimum for many busy writers; longer is kinder, especially around holidays, finals, research deadlines, or a committee process. Give the writer a firm date that is earlier than your actual last possible date, then follow up respectfully.

Give the writer material, not a script

A useful writer packet might include:

  • your résumé or current activities list;
  • a draft of the Personal Statement, if it is developed enough to help;
  • your transcript and a brief explanation of any context they need;
  • the schools or programs and the general type of letter required;
  • the submission instructions, request ID, and deadline;
  • a short page of reminders: projects you completed, moments you discussed, obstacles you navigated, feedback you used, and qualities you hope the writer can assess.

This is not permission to write the letter yourself. Do not hand someone a paragraph and ask them to sign it. The writer should decide what they can honestly say. Your job is to make the relevant evidence easy to find and the logistics hard to misunderstand.

If the writer asks what you hope the letter will emphasize, answer with qualities grounded in examples: how you approach uncertainty, how you work with a team, how you respond to criticism, how you communicate with people who need patience, or how you sustained a responsibility while managing competing demands. “Please say I am passionate and hardworking” is not useful to either of you.

Waiving access

Application systems may ask whether you waive your right to review a letter. The usual recommendation is to waive access when you are comfortable doing so, because schools may place more trust in a confidential evaluation. In AMCAS, once a letter is received, the program does not provide it to you or your letter author. You should understand what you are waiving before you select it, and follow the current instructions for the service you are using.1

You do not need to see a letter to evaluate the process. You can ask whether the writer feels able to write strongly, provide a clear deadline, confirm that they submitted it, and check that the application service received and assigned it correctly.

Committee letters and packets

Your college may offer a committee letter, a letter packet, or neither.

  • A committee letter is an evaluation written by a prehealth committee or advisor, sometimes accompanied by individual letters.
  • A letter packet is a set of letters assembled and distributed by the institution, often without a single committee evaluation.
  • An individual letter represents one writer.

These are not interchangeable in how schools interpret them. If your school offers a committee process, learn its eligibility rules and internal deadline early. Some medical schools strongly prefer or require the committee letter; others accept individual letters or packets. If you do not qualify for your committee's process, or your undergraduate institution does not offer one, that is a logistics difference — not proof that your application is weaker. Follow the receiving school's alternative instructions.

For AACOMAS, letters may be submitted through the application or through alternatives specified by the college, such as Interfolio. Requirements vary by osteopathic college, so verify them directly rather than assuming the AMCAS workflow applies.2

Track the handoff

Keep a letter tracker with:

  1. writer and letter type;
  2. date requested and promised date;
  3. submission service and request ID;
  4. date received by the service;
  5. schools to which the letter is assigned;
  6. whether the school has marked the file complete.

For AMCAS, letters can arrive after the primary is submitted and are forwarded on a rolling basis once received and assigned. That does not mean every school will consider your file complete without its required letters. A letter sitting in a service inbox but not assigned to the right schools is still a problem.1

If a deadline is approaching, send a brief, respectful reminder with the original instructions attached. If the writer can no longer submit, do not quietly leave the old letter request in place and hope it resolves itself. Update the application service and ask the school or advising office what replacement is acceptable.

When the letter arrives, send a thank-you. When the cycle ends, update your writers. They invested time in your future, and a short note about what happened is part of maintaining the relationship.

What makes a letter useful

The best letters are specific without becoming theatrical. They give a reader evidence of how you behave in a real setting: how you handled a difficult question, treated a quieter teammate, returned after a poor result, accepted correction, cared for a responsibility, or grew into a more capable person.

You cannot control the exact story a writer tells. You can choose writers who have actually seen you, give them accurate context, and avoid asking them to praise qualities they cannot verify. That is the whole strategy.

Common mistakes

  • Choosing a famous writer who barely knows you.
  • Assuming every school wants the same letter combination.
  • Asking too late or giving no realistic deadline.
  • Asking for a “letter” without asking whether the writer can make it strong.
  • Sending a résumé but no reminder of the work the writer actually observed.
  • Writing the letter for the writer.
  • Forgetting that committee letters and packets have different meanings.
  • Waiving access without understanding what the waiver means.
  • Failing to assign a received letter to the correct schools.
  • Disappearing after the writer submits it.

The Foundation stage is where many of these relationships begin. The Application stage shows where the requests fit in the cycle, and the Primary Application guide covers the assembly and tracking mechanics.

Letter requirements, committee policies, submission services, deadlines, and access rules vary by school and application cycle. Verify the current instructions in AMCAS Section 6, AACOM's application process, and each school's admissions page. This is educational information from one physician's perspective, not admissions advice. — Last reviewed: 2026-08-02
