Residency Recommendation Letter: 6 Samples That Get Read
By Mustafa Tarabya, founder of CVBooster · Published · Updated
9 min read
A residency recommendation letter is a one-page letter, uploaded through ERAS, in which a physician who supervised the applicant compares them with other students and gives specific clinical examples of their work. The constraint is that every letter a program director reads says "excellent", so only comparison and detail move the reader. The University of Washington's guidance for faculty tells writers to "Describe skills and abilities relating to competencies rather than personality traits", and the samples below follow that rule. Six complete residency recommendation letter samples, checked in October 2026, for students, research mentors, chairs and international graduates. Written by Mustafa Tarabya, who hired for his own company, read every application himself and now writes CVBooster's guides.
Program directors have read the phrase "a pleasure to work with" so many times it has stopped being a sentence. It is now punctuation. The letters that matter say "top five of the forty students I have supervised" and then prove it.
Clerkship attending, internal medicine
The core clinical letter. The attending supervised the student on the wards and can describe how they presented patients, reasoned and worked with the team.

Medical student: internal medicine clerkship attending (204 words)
Dear Program Director,
It is with great enthusiasm that I recommend Ms. Aisha Rahman (ERAS 2026104471) for a position in your internal medicine residency program. I am an Associate Professor of Medicine and supervised Aisha for four weeks on the inpatient general medicine service at University Hospital during her third-year clerkship. Aisha has waived her right to see this letter.
Over twelve years I have supervised more than 150 students on this service, and Aisha is among the top five. Her presentations were organized and honest: she told me what she knew, what she did not, and what she had already looked up. On her second week she admitted a patient with hyponatremia, worked through the differential before rounds, and correctly suspected medication-induced SIADH. She followed the patient's sodium every morning and adjusted her plan with the resident.
She was the student the interns asked to help. She wrote clear notes, called families with updates when asked, and never left a task unfinished at sign-out.
Aisha will be an outstanding resident. I recommend her with my highest enthusiasm and would be glad to have her in our own program.
Sincerely, Michael Torres, MD Associate Professor of Medicine, Clerkship Site Director University Hospital, (555) 640-2290
Sub-internship or away rotation
A sub-I letter carries extra weight because the student acted at intern level. Describe the responsibility and how the student handled it.

Medical student: surgery sub-internship letter (169 words)
Dear Members of the Selection Committee,
I am pleased to recommend Mr. Jacob Feld (ERAS 2026118852) for your general surgery residency program. I supervised Jacob during his four-week acting internship on our acute care surgery service. He has waived his right to see this letter.
During the rotation Jacob carried four to six patients as the primary student, wrote orders for co-signature, and presented on rounds at intern level. On one night call he recognized early signs of sepsis in a post-operative patient, called the senior resident, and had cultures and fluids started before I arrived. In the operating room he knew the anatomy, asked useful questions and closed skin carefully.
Among the sub-interns I have supervised in the last five years, I would place Jacob in the top ten percent. He works hard without being asked, accepts feedback the same day, and the nursing staff trusted him.
I give Jacob my strongest recommendation for surgical training.
Sincerely, Elena Park, MD, FACS Assistant Professor of Surgery, Acute Care Surgery
Research mentor
Research letters should still say something about clinical potential. Name the project, the student's role and what they produced.

Medical student: research mentor for a radiology applicant (165 words)
Dear Program Director,
I write in strong support of Ms. Grace Okonkwo (ERAS 2026120039), who worked in my imaging research group for eighteen months. Grace has waived her right to view this letter.
Grace led a retrospective project on missed findings in emergency chest CT. She wrote the protocol, obtained IRB approval, reviewed 600 studies with two attending radiologists and presented the results at our regional radiology meeting. She is first author on the manuscript now under review.
What impressed me most was her judgment. When the early data suggested a result that would have been easy to publish, she noticed a sampling problem and insisted we fix it first. That is the habit I want in any physician who reads images.
She is also a good teacher. She trained two first-year students in our review method, and both stayed with the group.
I recommend Grace without reservation for diagnostic radiology.
Sincerely, Samuel Ortiz, MD, PhD Professor of Radiology, Director, Imaging Outcomes Research Group
Department chair letter
Some specialties ask for a chair's letter. It summarizes the student's performance across the department and is often based on other faculty's evaluations.

Medical student: department chair letter, internal medicine (147 words)
Dear Program Director,
On behalf of the Department of Medicine, I am pleased to support the application of Mr. David Chen (ERAS 2026107715) to your internal medicine residency program. Mr. Chen has waived his right to see this letter.
I met with David to review his application, and I have read the evaluations from his clerkship and sub-internship. His attendings describe him consistently as a strong clinical reasoner with excellent follow-through. He earned honors in both rotations, and his sub-internship attending ranked him in the top tier of students she has supervised this year.
Outside the wards, David co-led the student-run free clinic for two years, where he built a follow-up system for patients with uncontrolled hypertension.
Based on his record and our conversation, I expect him to be an excellent resident and future colleague. I recommend him highly.
Sincerely, Rebecca Hall, MD Chair, Department of Medicine
International medical graduate, US clinical experience
IMG letters must address US clinical experience directly, because that is what programs look for. Say what the applicant did, how independent they were and how they compare.

International graduate: observership attending, family medicine (162 words)
Dear Program Director,
I am writing to recommend Dr. Ravi Menon (ERAS 2026131254) for your family medicine residency program. Dr. Menon completed a twelve-week externship in my outpatient clinic at Valley Community Health Center, where I am the medical director. He has waived his right to see this letter.
Dr. Menon saw patients under my supervision, took histories, examined patients and presented plans to me before I saw them. His plans were safe and practical, and by the fourth week I was changing very little. He has a natural way with patients who are anxious about the health system, and several asked to see him again.
Compared with the US students and international graduates who have rotated with me, Dr. Menon is in the top quarter for clinical knowledge and the top few for patient communication.
He will be an asset to a family medicine program, especially one serving a diverse community.
Sincerely, Laura Benson, MD Medical Director, Valley Community Health Center
Reapplicant: updated letter
When an applicant reapplies after not matching, a new letter from someone who supervised them during the gap year matters more than an old one.

Reapplicant: research year supervisor, updated letter (123 words)
Dear Program Director,
I recommend Dr. Hannah Weiss (ERAS 2026099820), who has worked as a clinical research fellow in our Department of Pediatrics since July 2025, after not matching in the last cycle. She has waived her right to see this letter.
In this year Hannah has coordinated enrolment for our asthma education trial, seen families in clinic alongside our pediatricians, and presented our interim results at grand rounds. She took feedback from her first application seriously; her clinical presentations are now concise and her plans well reasoned.
I have watched her grow in confidence and skill over twelve months. I would be glad to have her as a resident in our own program.
Sincerely, Thomas Grant, MD Associate Professor of Pediatrics
The format residency programs expect
The University of Washington's faculty guidance sets out the basics. Use letterhead: "Use official School of Medicine or hospital letterhead." Identify the applicant by their application number. Include the waiver: "Indicate that the student has waived the right to see the letter (if applicable)." And keep it to a page: "LORs typically are about a page in length."
The same guidance warns writers: "Do not agree to write a letter for a student if you cannot honestly give a strong recommendation." If a writer hesitates when you ask, take the hint and ask someone else. A lukewarm letter does more harm than one fewer letter.
Letters are uploaded directly by the writer through the ERAS Letter of Recommendation Portal, and the applicant assigns them to programs. The University of Nevada, Reno tells its students to "Sign the waiver granting confidentiality to the letter writer", because programs weigh confidential letters more heavily. The Match itself is run by the NRMP, which publishes the calendar your letter deadlines work back from.
How to ask for a residency letter
Ask attendings who saw you work closely, not the most famous name you met for a day. Ask in person or by email at least four to six weeks before you need the letter, and send a short packet: your CV, personal statement draft, the specialty, your ERAS ID and two or three cases they may remember. Our personal statement examples can help with the draft you send.
Your CV is part of the packet. The how to write a personal statement for a job guide covers the structure, and for nursing letters see the nursing recommendation letter samples. For non-medical letters, our reference letter examples cover employers and teachers.
Frequently asked questions
How many letters of recommendation do you need for residency?
Most programs ask for three or four letters, and ERAS allows up to four per program. Check each program's requirements, because some specialties want a letter from a department chair or a standardized letter. At least two letters should come from physicians in the specialty you are applying to.
Who should write my residency recommendation letter?
Ask physicians who supervised you closely in the specialty you are applying to, usually clerkship or sub-internship attendings. A research mentor can add a strong letter if they also saw your clinical skills. A detailed letter from an assistant professor who knows you well beats a short one from a famous name.
Should I waive my right to see my letter of recommendation?
Yes, in almost every case. Programs give more weight to confidential letters because the writer can be candid. Medical schools routinely advise students to sign the waiver, and the letter usually states that the applicant has waived the right to see it.
How long should a residency recommendation letter be?
About one page. University medical school guidance for faculty says letters are typically about a page. Program directors read many letters per applicant, so a focused page with comparison and two or three clinical examples is stronger than a long general letter.
When should I ask for residency letters of recommendation?
Ask soon after the rotation, while the attending remembers you, and give them at least four weeks before your deadline. Many students ask in spring or early summer of their final year so letters are uploaded before applications open to programs in September.
