Overview
Harvard Medical School recommendation letter overview
Harvard Medical School evaluates letters of recommendation as part of a holistic application process. Letters are typically routed through AMCAS Letters Service (or the relevant centralized service such as AACOMAS or TMDSAS), and while the specific number or format can shift slightly year to year, reviewers consistently look for direct, recent, and specific observations relevant to MD and pre-health applicants.
Harvard Medical School requires a minimum of three letters: at least two from professors who taught the applicant in a science course and at least one from a non-science professor. Applicants may submit up to six letters total, and a premedical committee evaluation packet counts as one letter toward that six-letter maximum. Letters from research supervisors can be submitted in addition to the six-letter cap.
Because exact letter counts, required forms, and deadlines can be updated by Harvard Medical School from year to year, applicants should always confirm the current cycle's instructions on the school's own admissions page or application portal before asking recommenders to submit anything. This page is a planning and drafting resource, not a substitute for the school's official requirements.

Who should write it
Who should write your Harvard Medical School recommendation letter
For Harvard Medical School, the strongest recommenders are typically a pre-health committee or advisor, science (biology, chemistry, physics, math) faculty who taught the applicant in a graded course, a research principal investigator, and/or a physician who supervised clinical shadowing or work. The admissions committee is less interested in a recommender's title or seniority than in whether that person can describe academic rigor in science coursework, intellectual curiosity, clinical exposure with specific, first-hand examples. An applicant should choose recommenders who have worked with them closely and recently enough to recall real moments, not simply the most impressive name available.
Common mistakes
Common mistakes applicants make
- Assuming every school treats a Committee Letter the same way a single individual letter counts toward the minimum.
- Waiting until October to request letters, leaving recommenders only days before the secondary deadline.
- Asking a famous or senior physician who barely knows the applicant instead of someone with direct, recent contact.
- Not telling the recommender which specific program, MD/PhD track, or mission focus the letter should speak to.
- Letting the letter read like a CV restatement instead of describing specific clinical, research, or classroom moments.
