The National Resident Matching Program (NRMP) oversees the Match for most residency and fellowship positions in the United States. Understanding how the process works reduces anxiety and helps you make informed decisions at every stage.
How the NRMP Matching Algorithm Works
The NRMP uses a computerized mathematical algorithm known as the Gale-Shapley applicant-proposing algorithm. It is designed to produce the best possible outcome for applicants while respecting the preferences of both applicants and programs.
- 1
The algorithm starts with your top choice
It attempts to place you at the program ranked first on your rank order list, provided that program has also ranked you and has an available position.
- 2
If your top choice cannot accommodate you
The algorithm moves to your second choice, then third, and continues down your list until a tentative match is secured or all options are exhausted.
- 3
Tentative matches can be displaced
A tentative match can be broken if a more preferred applicant becomes available later in the run. The algorithm processes every applicant simultaneously.
- 4
Final matches are mutual
A tentative match becomes final only when both the applicant and the program have mutually ranked each other and no more preferable option exists for either party.
Because the algorithm is applicant-proposing, it always attempts to honor your highest possible preference first. This structure mathematically favors the applicant. The proven optimal strategy is to rank programs in order of your true personal preference, not where you think you are most likely to match. Gaming the algorithm by ranking strategically rather than honestly has been mathematically proven to produce worse outcomes for applicants.
Rank Order List Strategy
Your rank order list is a binding commitment. Any program you rank and are matched to becomes your required training position. The algorithm does not consider your perceived likelihood of matching.
Core rules for building your rank list
- Rank programs in order of your genuine personal preference, not where you think you are most likely to match.
- Include every program where you interviewed and would be willing and able to train. Longer lists correlate with higher match rates.
- Never rank a program you would not accept. The match is binding.
- Include a balanced mix of reach, target, and safety programs. See the program selection guide for how to categorize programs.
Ranking strategically rather than honestly. Applicants sometimes rank programs they think will rank them highly over programs they actually prefer. The Gale-Shapley algorithm is mathematically proven to produce the best possible outcome when applicants rank honestly.
Rank where you want to go. That is the only strategy that works.
Couples Match Guide
The Couples Match allows any two applicants participating in the same Match to link their rank order lists so they can attempt to be placed in the same geographic area.
How it works
- Each partner creates their own individual rank order list independently.
- You link your accounts in the NRMP system and create paired program combinations.
- The algorithm treats each pair as a single unit and matches the couple to their highest-ranked acceptable pair where both partners receive positions.
- If no paired match is possible, the algorithm does not automatically fall back to individual matching unless you have included unpaired options.
The no-match code
You may include a special no-match code (999999999) on your list. This allows one partner to match while the other remains unmatched if that is the only way to secure a position for the first partner. Whether to include this code is one of the most consequential decisions a couple makes and should be discussed carefully before certifying your list.
Tell programs early that you are participating in the Couples Match. This allows them to coordinate interview schedules and understand your paired preferences. Most programs are familiar with the process and will work with you. Transparency about couples status is almost always better than trying to hide it.
What to Do If You Do Not Match: SOAP
The Supplemental Offer and Acceptance Program (SOAP) is a structured process that allows eligible unmatched or partially matched applicants to apply for unfilled residency or fellowship positions during Match Week. It replaced the old unstructured scramble and is significantly more organized and fair.
Learn your match status
You find out whether you matched but not where. Eligible unmatched applicants receive access to the List of Unfilled Programs.
Apply through official channels
Submit applications to unfilled positions. You may not contact programs directly. Programs initiate all contact.
Rapid offer and acceptance rounds
Programs review applications and extend offers in a series of rapid rounds, typically four. Each round has a strict deadline for acceptance.
Accept carefully
Once you accept a SOAP offer, it is binding. Review every offer carefully before accepting. You cannot un-accept an offer.
You must be fully registered with the NRMP and verified as eligible to begin training on July 1. Strict communication rules apply throughout SOAP. Contacting programs directly outside the official system is a serious violation. Follow the official process precisely.
Have your ERAS application updated and ready before Match Week begins. Know which specialties and geographic areas you would consider. Have your letters of recommendation current. Applicants who are prepared to act immediately on Monday morning have a significantly better SOAP experience than those who scramble to update materials during the process itself.
Match Timeline Overview
Exact dates vary slightly each cycle. The sequence below reflects the consistent structure of the residency Match. Fellowship Match timelines follow a similar sequence but on their own calendars depending on the specialty.
Early Summer
MyERAS and NRMP registration open. Begin drafting your personal statement, requesting letters of recommendation, and building your ERAS CV in the correct format.
Late Summer to Early Fall
Applications submitted to programs. Submit before programs can view your application. Early submission correlates with more interview invitations. NRMP registration continues.
Fall through Early Winter
Programs review applications and extend interview invitations. Interview season runs through January. Respond to invitations promptly. Send thank-you notes the same day or next morning.
Mid-Winter
Rank order list entry opens. Build your list carefully. Rank honestly in order of genuine preference. Review your list with trusted advisors before certifying.
Late Winter — Rank List Deadline
All rank lists must be certified by the NRMP deadline. This is a hard deadline. Missing it means you do not participate in the Match. Set calendar reminders weeks in advance.
Match Week — Mid-March
The culmination of the entire process. See the Match Week breakdown below.
Match Week — Day by Day
Mental Health During the Match Process
The Match process involves long periods of waiting, uncertainty, and high stakes. Protecting your mental health during this period is not optional — it directly affects your performance during interviews and your ability to make good decisions about your rank list.
Maintain Perspective
The Match is one chapter in a long career. Your worth as a physician is not determined by a single outcome. Many physicians who did not match their top choice went on to have exceptional careers.
Use Your Support System
Lean on trusted peers, mentors, family members, or professional counselors who understand the medical training journey. Isolation during high-stress periods amplifies anxiety.
Protect Physical Health
Sleep, regular exercise, and consistent nutrition directly support emotional resilience. Applicants who neglect physical health during the Match process are more vulnerable to anxiety and impaired decision-making.
Set Boundaries
Limit time spent checking forums, comparing stats with peers, or reading Match outcome stories online. These activities consume significant emotional energy and rarely provide useful information.
Use Grounding Techniques
When anxiety spikes acutely, grounding exercises bring attention back to the present moment. The 5-4-3-2-1 exercise — name five things you see, four you hear, three you feel, two you smell, one you taste — is simple and effective.
Seek Support Early
Many applicants experience imposter syndrome and anxiety throughout this process. These feelings are normal and widely shared. Seeking support from a counselor before anxiety becomes severe is a sign of self-awareness, not weakness.
The match starts with your personal statement.
