The first thing to know is the letters required for admission to medical school are Letters of Evaluation, not Letters of Recommendation.
What’s the difference?
A letter of recommendation is an endorsement. It’s advocating on someone’s behalf, telling a med school, for example, why an individual would be a great addition to their class.
A letter of evaluation is a critical assessment of a candidate’s fitness for medical school. It analyzes the strengths and weaknesses of the individual based on specific criteria. It’s more objective than a recommendation. And it asks the letter writer to compare a med school candidate against other students in the same class and historically against all students the letter writer has met/taught over their career.
General guidelines for LOEs
Every single med school has its own specific requirements for LOEs, both in the number of letters allowed and from whom they must come.
This information will be available on the admissions webpage of each medical school, and in MSAR (Medical School Admission Requirements) for MD schools, and in Choose DO Explorer for DO schools.
MSAR is a database maintained by AMCAS that is updated annually that holds a wealth of information about every MD program in the country. Access to all the data is by subscription only. Cost for a 1 year subscription is $33.
Choose DO Explorer is the DO equivalent to the MSAR (but with less data). It’s free to use, but requires registering with AACOM.
Applicants must explicitly follow a med school’s directions on the number of LOEs and who writes them. Send too few letters or send letters from the wrong type of letter writer, then the application is considered incomplete and will never get reviewed. Send too many letters—the applicant has then demonstrated an inability to follow directions and will be rejected without ever being reviewed.
Generally speaking a medical school requires between 3 and 5 letters of evaluation for an application. AMCAS allows applicants to upload up to 10 LOEs to their application account. ACOMAS allows applicants to upload 6. Once a student has selected which medical schools they are going to apply to, they may assign which individual letters they want to be sent to each medical school. Only the assigned LOEs will be sent.
