USMLE Step 3 Exam Dates in 2026: What You Need to Know

Step 3 comes with its own logistics, different from Step 1 and Step 2 CK: it usually happens during residency, it has its own eligibility rules on top of the earlier Steps, and 2026 brought a real change to how test day is structured. This guide walks through the practical questions, based on current USMLE instructions.

When can I take the USMLE Step 3 exam?

Most residents take Step 3 during their first year of residency, PGY-1, often within a window set by their state medical board or program. USMLE recommends applicants have completed, or be near completion of, at least one postgraduate training year in an accredited US graduate medical education program, though this is guidance rather than a strict requirement. If you need an H-1B visa, passing Step 3 before residency can matter, since some visa sponsorship pathways require a medical license, which in turn requires passing Step 3.

The exam is offered most of the year, on most weekdays and many Saturdays, except for major holidays and a maintenance window NBME and FSMB have historically used in early January.

Who is eligible to take Step 3?

Step 3 has one prerequisite the earlier Steps do not: you must pass Step 1 and Step 2 CK first.

• US and Canadian MD graduates: have completed Step 1 and Step 2 CK, and meet any additional requirements of the state or jurisdiction they are applying through.
• US DO graduates: have completed Step 1 and Step 2 CK, meeting the same underlying requirement.
• International medical graduates (IMGs): in addition to passing Step 1 and Step 2 CK, must hold a valid, unexpired ECFMG Certificate at the time of application and on the actual testing date.

How do I register for Step 3?

As of 2026, US and Canadian applicants register for Step 3 directly through the NBME. International applicants register through the FSMB, as of a service transition that took effect January 12, 2026 for international applicants and January 26, 2026 for US and Canadian applicants, covering all three Step exams. Step 3 applications have historically run through FSMB more often than the earlier Steps, since state medical boards are directly involved in licensure, so confirm the current process through your own state board alongside the FSMB or NBME portal.

As with the earlier Steps, you select an eligibility period as part of your application, then receive a scheduling permit by email, which you use to book your actual appointment through Prometric.

How far in advance can I schedule my Step 3 exam?

You can schedule your Step 3 appointment through Prometric up to six months in advance. Because Step 3 is a two-day exam, you will typically book both days together, and test center availability for two consecutive or near-consecutive days can be tighter than for a single-day Step exam, so book early in your eligibility period.

For the actual studying, our USMLE Step 3 study guide covers a sample plan built around a resident's schedule.

How much does it cost to register for Step 3 in 2026?

The Step 3 application fee is higher than Step 1 or Step 2 CK, reflecting its two-day format: around $955 for the 2026 and 2027 eligibility periods, paid by credit card and non-refundable. International applicants and some other circumstances can carry additional processing fees.

How can I change my Step 3 exam date?

If you have already scheduled your Step 3 exam, you can reschedule it through the Prometric website. As with the earlier Steps, changing your appointment inside 45 calendar days of your scheduled date carries a fee, so if you think you might need to move your date, do it as early as possible, and remember you are coordinating two test days, not one.

Did the Step 3 exam format change in 2026?

Yes. On March 10, 2026, Step 3 moved to updated test delivery software, following the same pattern as the other two Steps: more blocks, each shorter, with the total questions, total seat time, scoring, content outline and CCS format unchanged.

• Day one is multiple-choice only: up to 232 questions across 12 blocks of 18 to 20 questions, 30 minutes per block, in a roughly 7-hour day including breaks and an optional tutorial.
• Day two combines multiple-choice questions with Computer-based Case Simulations (CCS): up to 180 multiple-choice questions across 9 blocks of 20 questions, 30 minutes per block, plus 13 to 14 CCS cases, each capped at 10 or 20 minutes of real time, in a roughly 9-hour day.

Block counts and exact timing are set by the NBME and can be adjusted, so confirm the current structure on USMLE.org close to your test date rather than relying on any single guide, including this one.

When will I get my Step 3 results?

Results are typically available within four weeks of your test date, though a number of factors can delay reporting, so USMLE recommends waiting at least eight weeks before you inquire about a missing score. Step 3 still reports a three-digit score rather than pass/fail. You will be notified by email once your report is available.

Preparing for the exam

Since Step 3 is offered once you are already in residency, treat a real dedicated study block as a bonus rather than a given, and build a small daily habit around your clinical duties well before your test date. Practice multiple-choice questions across every discipline in the blueprint, and pair that with dedicated CCS practice, since a multiple-choice question bank alone will not prepare you for day two.

Frequently asked questions

Is there a fixed USMLE Step 3 exam date in 2026?

No. You apply for a roughly three-month eligibility period, then book actual appointments inside that window through Prometric, on a first-come, first-served basis.

Do I need to pass Step 1 and Step 2 CK before Step 3?

Yes. Step 3 eligibility requires having already passed both earlier Steps, and IMGs must also hold a valid, unexpired ECFMG Certificate.

Did the Step 3 exam format change in 2026?

Yes. On March 10, 2026, Step 3 moved to updated test delivery software with more, shorter blocks across both test days. Total questions, seat time, scoring, content and the CCS format stayed the same.

Is Step 3 pass/fail like Step 1?

No. Step 1 moved to pass/fail in 2022, but Step 3 still reports a three-digit score, the same as Step 2 CK.

How long do Step 3 results take?

Typically within four weeks, though USMLE recommends allowing at least eight weeks before asking about a delayed report.

What about Step 1 and Step 2 CK exam dates?

Both earlier Steps follow the same eligibility-period system, with their own 2026 format changes and fees. See our USMLE Step 1 exam dates guide and USMLE Step 2 CK exam dates guide for the specifics.
