Does a Letter of Intent Change Your Rank List?

Does a Letter of Intent Change Your Rank List? What the Evidence Shows

Short answer: nobody can tell you that it will, and nobody can honestly tell you that it won't. In NRMP's latest survey to publish this factor, about one program director in five said post-interview contact entered ranking decisions. Most program directors in specialty surveys say applicant declarations don't change their lists. A letter is at most one small input, and after certain dates it can't be one at all.

What NRMP's program director survey shows

In NRMP's 2021 Program Director Survey, 20.7% of program directors across specialties cited "Other post-interview contact" as a factor in deciding whom to rank. By comparison, 64.7% cited "Perceived interest in program" and 87.1% cited "Interpersonal skills" (checked 2026-09-28). It is the latest edition with a static per-factor table; 2026 factor figures are only in NRMP's interactive report, so we don't quote one.

Caveats:

• It doesn't isolate letters of intent, and it measures whether the factor was considered, not whether anyone moved.
• Specialties vary widely. In the same report, the figure was 5.6% in orthopaedic surgery (n = 36) and 3.6% in otolaryngology (n = 28), but 31.0% in anesthesiology (n = 42) and 35.3% in diagnostic radiology (n = 34).
• Sample limits: a 23.3% response rate (n = 1,033), in a virtual-interview year.

"Perceived interest in program" was cited three times as often, and the survey doesn't say how programs form that perception.

What specialty surveys show

These are small single-specialty surveys from different years. The pattern: most program directors say declarations don't change their lists, and a minority say applicant communication can, in either direction.

Some 2026–27 specialty guidance is direct. Dermatology's program directors say letters of intent and thank-you letters "are typically not used by residency programs in decision-making and lead to downstream pressures on applicants." Anesthesiology says letters of interest "will not be utilized to influence interview/rank list outcomes." The full specialty table is in the residency letter of intent guide.

Applicants send them anyway

In a 2024 survey of neurosurgery applicants, "Sixty-four (84.2%) respondents reported submitting a letter of intent (LOI) to their number 1 ranked program. Sixty-one (82%) felt pressured to send a LOI" (Laskay et al., World Neurosurgery). They felt pressured "to improve their rank status, fearing that it may harm them if they did not."

When a letter can't help, or shouldn't be sent

• After a program locks its list. Internal medicine, pediatrics and vascular surgery programs in NRMP's voluntary lock pilot lock by a target date of February 8, 2027; then they "cannot uncertify and edit their ROL under any circumstance." Check R3.
• After the Rank Order List Certification Deadline, March 3, 2027, 9 p.m. ET.
• When your specialty or program asks you not to. Dermatology and plastic surgery do.

What you actually control

You can't control whether a letter moves a list; you control whether it is accurate and specific. NRMP lets you "voluntarily communicate" interest and forbids asking for a ranking commitment. State your real interest once, give a reason only this program could prompt, and ask for nothing: that is a letter you can stand behind. See three annotated residency letter of intent examples.

If you decide to send one, you can check your draft against the residency letter of intent rubric. The feedback is qualitative: specificity, clarity, and anything that reads as asking about ranking. It doesn't write the letter or predict Match outcomes.
