How SOAP Actually Works

By Dr. Eye MD · Companion article to The SOAP & Reapplicant Playbook

SOAP stands for the Supplemental Offer and Acceptance Program. It is the NRMP's system for filling positions that remain unfilled after the main Match, and it happens during Match Week. If you didn't match, SOAP is your first and best shot at securing a position for the coming year. You need to understand exactly how it works, because it moves fast and the rules are strict.

One caution before the details: the National Resident Matching Program updates its Match Week schedule, eligibility rules, and fees every year. This article describes how the mechanics of SOAP generally work — always confirm the current year's exact dates and rules on nrmp.org before acting.

The timeline of Match Week

Match Week runs Monday through Thursday of one week in March. The exact dates shift each year, so confirm the current schedule on nrmp.org — the rhythm, which stays consistent, goes like this:

• Monday: You learn whether you matched. If you did not match, you are eligible for SOAP. Late in the day, the list of unfilled programs becomes available to eligible unmatched applicants, and you can begin preparing and submitting applications.
• Tuesday through Wednesday: SOAP offer rounds. Programs extend offers to applicants through the NRMP system, and applicants accept or reject them. There are a fixed number of offer rounds, each on a tight clock — offers expire quickly, and you must respond within the window.
• Thursday: Match Day for those who matched in the main algorithm, and the SOAP process concludes. Any positions still unfilled after SOAP move to the open market — programs fill them on their own, outside the NRMP.

The defining feature of SOAP is speed. From learning you didn't match to accepting a position, you may have about 72 hours. That is why preparation matters more than improvisation: you cannot write a new personal statement, chase down letter writers, and research hundreds of programs from scratch in three days. (The sprint itself is covered in the SOAP application sprint.)

Eligibility basics

To participate in SOAP, you generally must be registered with the NRMP, have submitted a certified rank-order list for the main Match, and be unmatched or partially matched when Match Week begins. There are specific rules for who qualifies — for example, rules differ slightly for applicants who matched to an advanced position but not a preliminary year. Because the NRMP refines these rules periodically, verify your own eligibility status on nrmp.org rather than relying on secondhand summaries, including this article's.

The mechanics

Applications

You submit applications to unfilled programs through the ERAS system during Match Week. You are limited in how many programs you can apply to — the cap exists to keep the process manageable for programs. Choose strategically: a tiered list of strong fits, strategic fits, and genuine safeties beats spraying applications everywhere.

Offers

Programs review applications and extend offers through the NRMP system in scheduled rounds. An offer is for a specific position. When you receive one, you see the program, the specialty, and a countdown clock. (Managing the offer rounds is its own skill — including what to do when the early rounds pass quietly.)

Acceptance and rejection

You accept or reject each offer within the round window. Here's the critical part: accepting an offer in SOAP is a binding commitment. It creates the same obligation as matching through the main algorithm. You cannot accept a SOAP offer and then keep shopping for something better. This is not a "hold my spot while I think" situation. So every decision you make during SOAP should be a decision you'd be willing to live with for a year or more.

Multiple rounds

If you don't get an offer in an early round, you stay in the system for later rounds. Programs that don't fill in one round make new offers in the next. Don't panic if round one passes quietly — a significant share of SOAP placements happen in later rounds.

The rules you cannot break

The NRMP enforces strict communication rules during SOAP, and violating them can get you removed from the process or barred from future matches. The big ones, as generally understood:

• Programs cannot contact you outside the system before offers. You cannot reach out to programs to express interest, ask for interviews, or lobby during SOAP. All communication flows through the official channels.
• You cannot contact programs either. No emails to program directors, no phone calls, no "just checking in." Let the system work.
• Verify the current rules. The NRMP publishes the official Match Week and SOAP rules each cycle. Read them. They are short, and ignorance is not a defense.

These restrictions feel brutal when you're used to hustling for opportunities. But they exist to keep the process fair when everything is moving at breakneck speed. Your job during SOAP is not to network — it's to submit the strongest possible application to the right programs and make clean, fast decisions when offers come.

What programs are actually in SOAP?

This is the question everyone asks, and the honest answer is: it varies every year. SOAP lists typically include a mix of preliminary medicine and surgery positions, transitional-year spots, and categorical positions in less competitive specialties or at less competitive programs. Some years there are surprises — solid programs in solid specialties that simply had an off year. The list is what it is; your job is to evaluate each opportunity on its merits rather than on what you imagined your Match Week would look like.

Common SOAP mistakes

• Applying only to your original specialty. If you went unmatched in a competitive field and there are two spots in SOAP against hundreds of applicants, your odds are terrible. The applicants who place well apply across reasonable options — prelim years, transitional years, and less competitive categorical fields.
• Treating the personal statement as an afterthought. Programs decide whom to interview largely from ERAS materials. A generic, un-tailored statement signals "I'll take anything," and programs would rather take someone who signals "I want to be here."
• Freezing during offer rounds. The clock is real. Applicants who haven't pre-decided their accept/reject thresholds waste precious minutes debating with family members who don't understand the system. Brief your people before Tuesday.
• Violating communication rules. It happens every year — someone emails a program director "just to express interest" and gets flagged. Don't be that person. The rules are the rules.
• Turning down a good offer while waiting for a perfect one. A bird in the hand, fully and completely. If your decision matrix says accept, accept.
