Letters of Recommendation

Who to ask

If you're applying to medical or dental school through the HPA preapplication process, you will request three to six letters of recommendation, which will be sent to your schools along with the HPA committee letter. At least two letters must be from evaluators who can comment on your ability in the sciences, at least one of whom has taught you in a science class at Princeton.

If you're applying to another health profession or are ineligible to receive the committee letter, research schools of interest to find out what they require.

When considering whom to approach for letters, think about whose letters will provide a balanced picture of you as an applicant. Letters are meant to provide details about any and all aspects of your candidacy, particularly your ability to navigate the rigorous medical school community, ways in which you will contribute to your medical school class, and suitability for a career in the health professions. The AAMC Letter Writer Guidelines outlines information schools are looking for – brainstorm who can provide this kind of information about you. HPA can provide additional guidance around choosing your recommenders.

When to ask

Give your writers at least a month before you want the letter to arrive at our office.

  • Applying with an HPA committee letter this spring? Contact potential writers in March / April, ask by early May -- letters are due to our office by June 1.
  • Senior applying in a future year? Many seniors meet with potential writers before they leave campus so that it's easier to schedule meetings with those writers. If requesting a letter more than a year prior to the time of application, we encourage you to ask your writer to submit a more current letter in your application year (even if it just means changing the date at the top of the letter).

How to ask

When asking for letters of recommendation, try to set yourself and your recommender up for success, as described below and in our webinar:

  • Ask directly [not by email]: in person, via online conference, or by phone. You can set up a meeting time to discuss the letter by email, but an in-person meeting is more professional and more personal.
  • Be detailed in how you ask and give the recommender the chance to say no: you want detailed, positive, strong letters of recommendation. If someone does not have the time, or does not know you well enough to provide this kind of letter, then it’s best to know in advance and look for someone who can be more enthusiastic. Ask your potential recommender if they will feel comfortable writing a strong / personal / enthusiastic letter for you in the time allotted.
  • Be prepared to discuss your candidacy and motivation for medicine in person, and provide additional information to make it easier for them to write:
    • HPA Request for a letter of recommendation (pdf version) (doc version) – this HPA form should be given to each recommender to facilitate their submission of letters.
    • The AAMC Letter Writer Guidelines that provide helpful guidance regarding what medical schools are looking for in letters of recommendation.
    • A copy of your resume/CV
    • A short autobiography providing background on yourself and your motivation for medicine
    • Anything else that they request
    • You can also refer them to the HPA Advice for Recommenders page
  • Negotiate deadlines by which the letter should be received in HPA with your recommenders. Follow up from time to time with reminders about the deadline.
  • Write a thank you note when the letter has been received. 
  • Stay in touch with your writers throughout the process, especially once you’ve been accepted and decided where you will attend, to thank them again for their support.


We encourage prospective applicants to open a free Interfolio Dossier account that is associated with the "Princeton - HPA" administrator account. This will give HPA access to any letters submitted on the applicant's behalf. There is no charge to use Interfolio in this way. Letters will be delivered to schools by HPA and should not be transmitted via Interfolio (which will incur a fee). 

Letter Storage with HPA

Students may request letters at any point in their Princeton career. HPA will store letters on file on the student's behalf for future applications for six years after graduation.
