Residency Update Letter After Interview: When to Send

Residency Update Letter After Interview: When to Send

The residency update you must send is the bad one. The 2027 Match Participation Agreement makes you disclose "circumstances that may delay or adversely impact" your ability to start training on time, such as a failed exam, a leave of absence or a graduation delay. A good-news update (a Step 2 CK score, an accepted paper, an award) is optional: one or two sentences of fact.

Most update-letter advice covers only good news, and treats the update as a second chance to pitch. The agreement reverses the priority. The obligation runs through the 45th day after your start date, so it does not end on Match Day. This page sorts updates into required and optional, shows which specialties welcome the optional kind, ties timing to the 2027 calendar, and gives three constructed updates, including the required one. If your update is the IMG kind (ECFMG certification, Step 3, a new US clinical letter), see the IMG update email guide.

Every NRMP, USMLE and specialty document quoted below was checked on November 7, 2026, for the 2027 Main Residency Match.

Two kinds of update: required and optional

Section 6.3 of the 2027 MPA, "Completeness, Timeliness, and Accuracy of Information", says:

"The omission of any information pertinent to a program's decision to rank an applicant may be deemed a violation of this Agreement. The applicant is responsible for disclosing any information regarding, among other things, the ability to satisfy program requirements; circumstances that may delay or adversely impact an applicant's ability to commence training with a matched program on the program's start date; or information relevant to licensure status or visa status."

And: "The applicant's obligation to submit complete, timely, and accurate information extends through the 45th day following the start date as listed in the appointment contract for the program position obtained through the Match or SOAP."

NRMP's Match Code of Conduct for Applicants says the same in plainer words: "It is the applicant's responsibility to inform programs at any time there are changes in the applicant's personal, educational, or professional experiences that could affect their ability to begin training."

The "Required?" column applies the quoted text; it is our reading, not an NRMP table. If you are unsure whether a change counts, ask your medical school's student affairs dean before you write.

What specialties allow after the interview

Optional updates follow the specialty's post-interview rules. The 2026–27 guidance, checked November 7, 2026:

• Pediatrics lists among allowed communication "Updates to provide to an application (e.g., new publication, award)." (APPD)
• Family medicine: "post-interview communication is discouraged unless it is a specific follow-up question from the interview or an update to an application." (OPDA family medicine)
• Psychiatry: "No post-communication aside from a simple thank-you is recommended." (OPDA psychiatry)
• Dermatology asks that "Post-interview communication of preference" not be sent (APD). Our reading: a factual update is not a statement of preference, so keep it to the fact.
• Plastic surgery (integrated): "There will be NO communication between faculty and applicants after the interview except for faculty communicating with their own advisees." (ACEPS)

The University of Maryland School of Medicine's residency manual gives the general rule: "If allowed, you may follow up with programs to provide updates after your interview – e.g., a new publication or award."

Our view: in psychiatry and plastic surgery, skip optional updates; in pediatrics and family medicine, a real update is the one email the specialty names as acceptable. A required disclosure is different. None of the specialty statements above says it overrides MPA §6.3, so send the required one as a short factual notice in every specialty, to the program coordinator with the program director copied. The countercase: if your medical school is already reporting the change to programs (for example, a revised graduation date in an MSPE addendum), your notice can be one line that points to it. Ask your dean's office what it has sent.

Step 2 CK and other scores: is it already in ERAS?

The USMLE transcripts page says: "Examinees using any residency application service—e.g., Electronic Residency Application Service® (ERAS®) or ResidencyCAS—should continue to follow instructions from the application owner for sending their USMLE transcripts to U.S. training programs. The USMLE program provides official source-certified USMLE data to both ERAS and ResidencyCAS."

Your official Step 2 CK result goes to programs through ERAS or ResidencyCAS, as that service directs. AAMC's ERAS pages returned HTTP 403 to our fetch, so we do not quote ERAS's own steps for sending a new score. Send it as your service directs; the email then names the exam, the release date and where the program can see the result. A screenshot is not the record.

Anesthesiology's guide flags the same gap for late documents: "programs may not notice documents added to ERAS after September 23. We suggest any late materials be uploaded AND emailed to the program coordinator of programs the applicant is applying to." (OPDA anesthesiology)

Send a good-news update when the fact exists, not saved up for a single "rank season" email. Send a required disclosure as soon as you know.

Three constructed updates

All three are constructed examples, written by us, not real applicant emails. Names, dates and programs are invented.

Constructed example 1: a Step 2 CK score (pediatrics)

Constructed example, written by us, not a real applicant email.

Subject: Remy Murata, AAMC ID 00000000, application update (Step 2 CK)

Dear Ms. Valdez and Dr. Galindo,

I interviewed with Hollowell Children's Pediatrics on November 18. My USMLE Step 2 CK result was released on January 12, and I have sent the transcript through ERAS following its instructions.

Thank you, Remy Murata

Two sentences of fact. It states the date, where the record is, and nothing about the number's meaning. Pediatrics names updates as allowed.

Constructed example 2: an accepted paper (family medicine)

Constructed example, written by us, not a real applicant email.

Subject: Sloane Rivera, AAMC ID 00000000, application update (accepted manuscript)

Dear Mr. Nguyen and Dr. Petrov,

I interviewed with Valley Family Medicine on December 2. On January 20, my manuscript on missed diabetic eye screening in rural clinics, listed in my application as submitted, was accepted for publication in a peer-reviewed journal.

Best regards, Sloane Rivera

It links the new fact to the line programs already have ("listed in my application as submitted"). Family medicine's guide names "an update to an application" as an exception to its discouragement of post-interview communication.

Constructed example 3: the required disclosure (leave of absence)

Constructed example, written by us, not a real applicant email.

Subject: Alex Rangel, AAMC ID 00000000, change to expected graduation date

Dear Ms. Brooks and Dr. Grabowski,

I interviewed with Northfield Internal Medicine on December 15. Because of a medical leave of absence in January, my school has moved my expected graduation date from May 14 to June 18, 2027. My school confirms I remain on track to start training on July 1, 2027, and the Office of Student Affairs, [contact], can verify the change.

Sincerely, Alex Rangel

Why it is built this way:

• The fact first, in one sentence. No apology paragraph and no medical detail beyond "medical leave of absence".
• The effect on the start date, because that is what MPA §6.3 asks about.
• A verifier. The school, not the applicant, confirms the change.
• No preference language. This is internal medicine, whose guidance tells programs to ask interviewees not to send thank-you notes. A required notice is not a thank-you note, and it carries nothing else.

If the change also needs explaining in an interview, see answering questions about a leave of absence. For how programs read gaps and red flags in the application itself, see residency application red flags.

What not to put in an update

• A ranking statement bundled in. An update and a letter of intent are separate decisions. Read the 2027 residency letter of intent rules before adding "you are my first choice".
• "Does this change my standing?" The Code says applicants "must not request a program director or any member of the recruitment team to disclose program ranking preferences or intentions."
• A full CV or a new personal statement. Programs have your application. Send the one new line.
• Anything that is not new. "My interest has grown" is not an update. The annotated residency letter of intent examples show a good-news update next to letters that make a ranking claim.

Questions about residency update letters

For waitlist and invite emails before the interview, see residency interview invite replies.

Do I have to tell programs I failed Step 2 CK?

If the result could affect your ability to satisfy program requirements or to start on time, MPA §6.3 makes disclosure your responsibility, and "The omission of any information pertinent to a program's decision to rank an applicant may be deemed a violation of this Agreement."

Do I need to email programs about a passing Step 2 CK score?

None of the NRMP documents quoted here requires it. Follow your application service's instructions so the official score reaches programs, and send a one-line update only where the specialty allows post-interview updates.

Can I send an update after March 3, 2027?

An optional update after March 3 cannot change any rank list. A required disclosure still goes out, through the 45th day after your start date.

How many updates is too many?

None of the specialty guides quoted here sets a number. Send an update when a new fact exists, one fact per email, and stop when the facts stop. Writing to a program you signaled? See what a signal does and doesn't tell a program.

Writing to a program where you rotated? See letters to your home or away program.

In pediatrics, APPD prefers an update to a letter of intent; see the pediatrics residency letter of intent page.

Some programs accept updates only through the portal; in OB-GYN each program states its own rule.

Get a free review of your update letter

Get a free Quick Review of your residency update letter against GradPilot's residency letter of intent rubric. It reads whether everything you present as new is a concrete, dated fact the program does not already hold, and whether any sentence asks the program about its ranking.
