ID fellowship match
IDSA administers the All-In Policy for adult ID fellowship programs participating in the National Resident Matching Program Medicine and Pediatric Specialties Match.


Most recent Match results
The recent Match, for appointment year 2026, welcomed 272 new colleagues into the field of infectious diseases. The number of physicians entering the field has increased since 2010, and we have also seen a significant increase in the number of training program positions offered. This year, less than half of the programs filled in the Match.

All-In Policy, ERAS access & NRMP participation
What is IDSA’s All-In Policy?
IDSA’s All-In Policy requires that all ACGME-accredited adult infectious diseases fellowship programs (except military programs):
- Register and participate in the NRMP Medicine & Pediatric Specialties Match
- Offer all training positions through the Match
- Execute an annual memorandum of understanding with IDSA
- Comply with NRMP Medicine & Pediatric Specialties Match policies
Between 2010 and 2014, fellowship applicant numbers declined while available fellowship positions increased, resulting in a significant number of unfilled programs. In response, IDSA adopted an All-In Policy beginning with the 2016 Match cycle to promote fairness, transparency, equity for applicants and programs, and workforce stability across the specialty. It was also implemented to preserve the integrity of the Match process.
What is IDSA’s relationship with NRMP?
As Match sponsor, IDSA works in partnership with NRMP to monitor compliance and ensure participation thresholds required to maintain the subspecialty’s access to the NRMP Medicine & Pediatric Specialties Match.
ERAS access & memorandum of understanding
Access to the Electronic Residency Application Service is contingent upon compliance with IDSA’s All-In Policy.
Programs must submit a signed annual MOU to IDSA in order to:
- Be listed in ERAS
- Receive applications through ERAS
- Participate in the NRMP Match
Programs that do not submit a signed MOU by the annual deadline will not be granted ERAS access for that Match cycle.
Programs submitting late MOUs may be added to ERAS and may access applications; however, ERAS does not notify applicants of programs added after the July 1 ERAS opening date.
Each year, IDSA executes:
- NRMP Program Directors’ Annual Sponsor Agreement
- SMS All-In Compliance Monitoring Agreement
As part of these agreements, IDSA affirms that:
- At least 75% of infectious diseases fellowship programs participate in the Match
- At least 75% of available fellowship positions are registered in the Match
Following Match Day, IDSA is required by NRMP to collect and report:
- Number of first-year fellows who began training July 1
- Number of fellows recruited post-Match
- Match fill data reconciliation
Programs will receive a reporting request each summer. The deadline is typically Aug. 15. Only one response per fellowship program should be submitted. This information is submitted to NRMP to monitor compliance with the All-In Policy.

Introduction to the Fellowship Match Webinar (February 2026)
NRMP and ERAS are separate organizations that support different components of the Match process:
ERAS is the application system through which candidates submit fellowship applications and programs review materials.
NRMP administers the ranking and Match process.
Applicants apply through ERAS and submit rank order lists through NRMP.
ID fellowship programs must be registered with NRMP and compliant with IDSA’s All-In Policy to access applications through ERAS.
Yes. IMGs may participate in the Match as long as they have completed all training required for the position, meet ACGME eligibility requirements and meet any eligibility requirements provided by the sponsoring institution. For visa guidance and additional support, visit IDSA’s IMG information page.
Like external candidates, internal candidates will need to register for and participate in the ID Match. Programs that wish to retain those candidates may place those candidates at the top of their rank order lists.
As the Match sponsor, IDSA supports the All-In Policy because it promotes fairness, transparency and equity for applicants and programs. By requiring all positions to be offered through the NRMP Match, the policy reduces pre-Match pressures and helps preserve a consistent, national recruitment process for the specialty.
Programs have flexible options and can create tracks (clinical, research and other) if desired to differentiate training options within individual programs. Training programs can designate to NRMP that unfilled positions in one track revert to an alternate track or remain unfilled. Programs should ensure that each eligible candidate understands about the different tracks.
NRMP has approved a Match exception for adult medicine/pediatric ID positions to allow programs to offer a position outside the Match for the second specialty. The exception is available regardless of the order of training for the combined fellowship applicant.
For example, if a position is offered to a candidate for a pediatric ID position within the Match, the candidate can simultaneously be offered an adult ID position outside of the Match.
Yes. The position must be placed into the Match and the trainee must go through the Match process. A program may guarantee the trainee a slot in the fellowship program. During the Match process, the program should rank the trainee first in the Match list.
Yes. The ID position in the combined fellowship program must go through the Match. For example, if a trainee is accepted into a critical care program, the ID fellowship program at that institution is permitted to guarantee that trainee that they will be ranked to Match in their ID program during a subsequent year, provided that the offer of the ID spot is not contingent upon the trainee ranking the institution’s ID program first on their list.
