OB-GYN Residency Letter of Intent: 2027 Rules
OB-GYN residency letter of intent: the specialty asks each program to state its own preference. Three program rules compared, 2026-27 dates, a sample.
OB-GYN Residency Letter of Intent: 2027 Rules
OB-GYN has no specialty-wide letter rule. The 2026–27 guidance asks each program "to be transparent about the program's preferences around and use of post-interview communication such as thank you notes and letters of intent." Programs post that preference on their own website or in ResidencyCAS. Of three programs we checked, one accepts letters of intent and two ask for questions only.
Our view: an OB-GYN letter of intent starts with a search, not a template. Before you write, find what the program has said about letters. If it accepts them, send one, to one program. If it asks for none, send none. If it says nothing, ask the coordinator one question.
Every OPDA, APGO and program page quoted below was checked on November 7, 2026. The guidance is for the 2026–2027 cycle and the 2027 Match. The residency letter of intent rules for 2027 cover NRMP's rules for all specialties. This page is about how OB-GYN hands the letter decision to each program.
What the 2026–27 OB-GYN guidance says
The OPDA obstetrics and gynecology guide gives the same structure before and after the interview:
"Pre-Interview Communication Guidance: The specialty is asking residency programs to be transparent about their preferences and use of pre-interview communication to secure an interview. Programs may specify their preferences on their individual program website or in ResidencyCAS."
"Post-Interview Communication Guidance: The specialty is asking residency programs to be transparent about the program's preferences around and use of post-interview communication such as thank you notes and letters of intent. Programs may specify their preferences on their individual program website or in ResidencyCAS."
Note who the guidance addresses. It tells programs what to publish. It doesn't tell applicants to send or not send. So in OB-GYN, the program's statement is the rule for that program.
Three OB-GYN programs, three answers
We read the application pages of three OB-GYN residency programs that show 2026–27 dates, on November 7, 2026. They aren't a sample of the specialty. They show the range you will find.
| Program (page checked) | What it says | The letter it implies |
|---|---|---|
| Columbia | "Does the program accept Letters of Intent (LOIs)?" "Yes." On thank-yous: "The program requests that applicants do not send thank-you emails or letters to the program, residents, or interviewers." | A letter of intent is fine. A thank-you note is not |
| University of Kansas | "…we do not recommend any other post interview communication, including thank you notes, and such communications are never included in ranking considerations. Communication from candidates about rank order or preference are highly discouraged and may be considered match violations." | No letter of intent and no thank-you. Questions only |
| Saint Louis University | "Please limit post-interview communication to specific program questions. Thank-you notes are not required or expected." | Questions only |
Columbia also says "The program will communicate with applicants to answer questions about the program, but will not respond to other types of communication." So even where a letter is accepted, expect no reply. Kansas says it "will not contact applicants after their residency interview."
One more pattern: none of the three asks for a thank-you note, and one asks you not to send one. In OB-GYN, the default advice to always send a thank-you can break a program's stated request. Read the page first. The residency interview thank-you email guide covers specialties where a note is welcome.
OB-GYN mechanics for the 2026–27 season
| OB-GYN rule (2026–27) | Source | Why it matters for a letter |
|---|---|---|
| Interview offers released October 27, 2026 | OPDA and APGO | Interviews, and the letters that follow them, come after this date |
| "Interviews occur no earlier than 11/01/2026" | OPDA and APGO | November 1, 2026 is the earliest interview date |
| "Notify applicants of final status (e.g. waitlist, rejection) by 11/25/2026" | OPDA and APGO | Waiting on a program after November 25? Ask a status question. Don't send a letter of intent to get an interview |
| "3 gold, 15 silver" signals; home and away programs may be signaled | OPDA | Your home program may already have your gold signal. The letter adds only what is new |
| One SLOE, "Required," inside ResidencyCAS | OPDA and APGO | Letters of evaluation go through ResidencyCAS, not your email |
| Second looks "should NOT be used to determine ranking" | OPDA | Don't time a letter to a second look |
| Lock pilot: "No" | OPDA | No pilot lock in OB-GYN. The March 3, 2027 deadline is the one that counts |
The APGO summary for the 2026–2027 cycle (updated May 2026) adds a detail the OPDA guide states differently. APGO says programs "Allow applicants a minimum of 48 hours to respond to interview offers". The OPDA guide says "a minimum of 24 hours". NRMP's 2027 Match Participation Agreement, section 6.2, says applicants may expect programs to "provide applicants no less than 48 hours to accept or reject an interview invitation". The binding text says 48 hours.
How signals and letters relate across specialties is on program signals and letters of intent. ResidencyCAS itself is covered in which specialties use ResidencyCAS.
How to find a program's preference
- The program's application or FAQ page. Search it for letter of intent, post-interview and thank you. All three programs above put it there.
- The program's ResidencyCAS listing. OPDA names it as the other place programs may post a preference.
- Interview-day materials. Some programs say it in the welcome talk or the email that follows.
- Nothing found? Email the coordinator one question, such as (our wording) "Does the program accept letters of intent after interviews?" That question asks about a policy, not about ranking.
Then apply the answer:
| What the program says | What you send |
|---|---|
| Accepts letters of intent | One letter, if this is truly your first choice |
| Discourages or asks for none | Nothing beyond a specific question |
| Questions only | A specific question, if you have one |
| Silent, and the coordinator doesn't answer | Our view: a short letter only to your true first choice. The countercase: if the program's culture page or interview day stressed limiting communication, send nothing |
Constructed OB-GYN letter of intent
Two constructed examples, written by us, not real applicant letters. Context (invented): Efua Danquah interviewed virtually on November 12, 2026 at a fictional program, Larkfield University OB-GYN. Its FAQ page says it accepts letters of intent and asks for no thank-you notes. By mid-February Larkfield is first on her list.
Weak version (68 words):
Dear Dr. Brennan,
Thank you so much for my interview! I wanted to follow up my thank-you note with this letter to say Larkfield is one of my very top choices and I would be honored to train there. I loved the residents and the culture. Please let me know if there is anything else I can do to improve my chances of matching with you.
Efua Danquah
Revised version (73 words):
Dear Dr. Brennan,
I will rank Larkfield first. On my November 12 interview day, the chief resident described the resident-run prenatal clinic for patients who speak Twi and Ga, and I want to keep caring for those patients across their pregnancies. Since my interview, my abstract on postpartum blood pressure follow-up was accepted for an April 2027 regional meeting. Larkfield's page welcomes letters of intent, so I wanted you to know.
Efua Danquah
What changed:
- No thank-you note. The program asked for none, so she doesn't mention sending one.
- One commitment. "One of my very top choices" becomes "I will rank Larkfield first," because that is now true.
- No request. "Anything else I can do to improve my chances of matching" asks the program to bargain over ranking. NRMP's Code of Conduct for Applicants says applicants "must not solicit or engage in post-interview communication for the purposes of influencing or ascertaining a program's ranking intentions."
- A reason from the interview day. "Loved the residents and the culture" becomes one clinic, who described it, and what she would do there.
- A dated update. An accepted abstract is new since November.
Questions about OB-GYN letters of intent
Do OB-GYN programs want letters of intent?
It depends on the program. The OPDA guide asks programs to state their preference "on their individual program website or in ResidencyCAS." Of the three programs above, one accepts them and two ask for questions only.
Should I send a thank-you note after an OB-GYN interview?
Check the program first. Columbia asks applicants not to send them, Kansas does not recommend them, and Saint Louis says they are "not required or expected."
When will I hear about OB-GYN interviews?
APGO and OPDA ask programs to notify applicants of final status (waitlist or rejection) by November 25, 2026.
Can I send letters of intent to two OB-GYN programs?
No. A first-choice letter can be true for one program only. If you aren't sure yet, wait until you are, or send none.
Get a free review of your letter of intent
Get a free Quick Review of your letter of intent against GradPilot's residency letter of intent rubric. Because OB-GYN leaves the rule to each program, paste that program's communication statement above your draft, and the review checks the letter against it. It also reads whether your reason comes from the interview day, whether your interest is stated at its true strength, and whether anything asks about ranking.
