Key facts
- NRMP classifies programs as categorical, preliminary (one-year transitional or specialty programs), advanced (start after required preliminary training) and physician positions.
- If you match to an advanced program, you need a separate first-year position; supplemental rank order lists link preliminary programs to advanced programs on your primary list.
- If you match to an advanced program but not a linked preliminary one, the algorithm does not continue down your list, and you must find a first year through SOAP or afterward.
- A preliminary year does not by itself guarantee a later categorical position, and visa sponsorship for prelim positions varies by program.
A preliminary or transitional year is a one-year first-year (PGY-1) position. IMGs use them in two ways: as the required first year before an advanced specialty that starts at PGY-2, or as a stepping stone after not matching to a categorical position, which is less certain. Both routes work through ERAS and the NRMP Match, with rank-list rules that are easy to get wrong.
The program types #
NRMP classifies programs in the Main Residency Match this way:
| Type | What NRMP says |
|---|---|
| Categorical | PGY-1 programs that provide the full training required for board certification in a specialty |
| Preliminary | One-year transitional or specialty programs |
| Advanced | Specialty programs that begin the year after the Match, after one or more years of required preliminary training |
| Physician | Programs starting in the Match year, reserved for physicians with prior graduate medical education |
In practice:
- A preliminary medicine or surgery year is a one-year position in that field. It provides a first year of training but not, by itself, board eligibility in a specialty.
- A transitional year is a broad year with rotations across several fields, often chosen before an advanced specialty. See the preliminary year glossary entry.
- An advanced position starts at PGY-2. You need a first-year position separately.
NRMP's 2026 Advance Data Tables report preliminary and transitional positions as their own rows alongside categorical ones. See those tables for current position counts.
How the Match handles them #
Primary and supplemental lists #
You submit a primary rank order list. NRMP says it can include categorical, preliminary and advanced programs, and that you must rank advanced programs on it to attach supplemental lists. A supplemental rank order list is a list of preliminary programs linked to one or more advanced programs on your primary list. NRMP notes that you can create several, and that each can be attached to multiple advanced programs, often organized by geography.
The algorithm places you in a preliminary position on a supplemental list only if you first match to the linked advanced program.
Joint advanced and preliminary programs #
Some institutions pair a preliminary program with its advanced program. NRMP says the preliminary program is restricted to applicants who rank the linked advanced program, and that it is placed on a unique supplemental list tied to that advanced program. Ranking it on that list is recommended so you have a continuous course of training.
Ranking preliminary programs on the primary list #
Ranking preliminary programs on your primary list is optional. NRMP notes it can guard against going unmatched but you may match to a one-year program. Only do this if you would accept a one-year position. See rank order list strategy.
Applying through ERAS #
You apply to preliminary and transitional programs through the same MyERAS application, but you choose programs by specialty. Per the AAMC 2027 guide, ERAS fees are based on the number of programs applied to per specialty, and pricing resets with each additional specialty. AMA's analysis of ERAS data lists transitional year among the specialties applicants most often add as an extra specialty. If a preliminary or transitional program is counted as a separate specialty in your account, expect it to be a separate line in your budget, and check the fee page. See ERAS and NRMP costs.
You can tailor your personal statement to a program or to a specialty, and you can upload more than one. A prelim program often wants to see why a one-year position makes sense for you. See the personal statement guide and applying to more than one specialty.
Strategy: when a prelim year makes sense #
| Situation | Reasonable use |
|---|---|
| You are applying to a specialty that starts at PGY-2 | Required first year; rank supplemental programs carefully |
| You did not match and want US training | A prelim year gives US clinical work and letters but not a guaranteed next position |
| You want to improve a weak profile | Possible, but a one-year job is not a substitute for a categorical offer |
| You need a visa | Check sponsorship first; it may rule out a position |
Our opinion: treat a stand-alone preliminary year as a one-year commitment with its own outcome, not as a plan that leads to a categorical position. Programs may decline to convert a prelim into a categorical resident, and the next year requires a new application. See categorical vs preliminary and reapplicant strategy.
Visa implications at a high level #
- ECFMG/Intealth is the sponsor for J-1 clinical training, and the J-1 is the most common visa used by IMGs entering residency, according to the CORD residency director toolkit. J-1 sponsorship for clinical training is generally for the duration of training, up to a maximum of about seven years.
- After J-1 training, the two-year home-country requirement generally applies unless waived. A prelim year on a J-1 is part of that training. See two-year home residency rule.
- H-1B sponsorship is institution-specific. Some programs sponsor H-1B only for categorical positions or not at all for preliminary ones. We could not confirm a general rule and the answer differs by program.
- A one-year position means your first document may cover one year, and you need a plan for what follows.
See J-1 vs H-1B, the J-1 process and H-1B for residents. Ask each program's GME office in writing which visas it supports for the specific position type.
Checklist #
- You know whether your target specialty needs a separate first year.
- Your supplemental lists are attached to the right advanced programs.
- You would accept every program you rank.
- You have confirmed visa support for the position type.
- You have a plan for year two.
Frequently asked questions
What is the difference between a preliminary and a transitional year?
Both are one-year PGY-1 positions. A preliminary year is usually in a specific field such as internal medicine or surgery, while a transitional year is a broad year with rotations across several fields. NRMP lists both as preliminary program types.
Does a preliminary year lead to a categorical position?
Not automatically. A prelim year gives clinical experience and sometimes connections, but a later categorical or advanced position is a separate application.
Do I need a preliminary year if I match to an advanced program?
Yes. Advanced programs start at PGY-2, so you need a first-year position. You can rank preliminary programs on a supplemental list, and some advanced programs are paired with a preliminary program.
Can IMGs get visa sponsorship for a preliminary year?
Often through the J-1 programme, but H-1B and J-1 policies differ by institution and by position type. Ask each program's GME office before you apply.
