From 2028, USMLE will officially switch to a completely new exam schedule system.
Instead of being able to proactively choose relatively flexible test dates all year round at Prometric centers as currently, candidates taking Step 1, Step 2 CK and Step 3 will only be allowed to take the test on a number of fixed dates predetermined by the USMLE.
This new system has an official name: Designated Testing Dates.
This important announcement has just been officially posted on the USMLE website on June 23, 2026.
The USMLE board said that starting in 2028, all three Step exams will only be held in a total of about 45 testing days per year. In return, they plan to expand the number of Prometric testing centers and reserve more test seats for candidates pursuing the USMLE route.
1. Expected USMLE exam schedule in 2028 for Step 1, Step 2 CK and Step 3
According to the preliminary schedule map that USMLE has just publicly announced, the exam dates for each Step are specifically allocated as follows:
Expected exam schedule Step 1:
Dates being highlighted on the schedule include:
- January: January 18
- February: February 7 and February 25
- March: March 13 and March 27
- April: April 3 and April 17
- May: May 8 and May 30
- June: June 5 and June 22
- July: July 17 and July 31
- August: August 17 and August 31
- September: September 5
- October: October 9
- November: November 27
- December: December 18, December 25 and December 26
Expected exam schedule Step 2 CK:
Dates being highlighted on the schedule include:
- February: February 10
- March: March 20
- May: May 1 and May 11
- June: June 1, June 15 and June 29
- July: July 6, July 13 and July 20
- August: August 7
- September: September 11
- October: October 16
- December: December 7
Strategic Note: According to the current calendar, the Step 2 CK exam does not have any test dates in January, April, and November. USMLE explains that the selection or removal of these months is calculated based on past testing demand, local medical training schedules, and timelines closely related to residency application season and licensing.
Expected Step 3 exam schedule:
Step 3 retains the same format as a two-day exam. Pairs of exam dates scheduled together include:
- January 27–28
- February 28–29
- March 9–10 and March 23–24
- April 27–28
- May 4–5
- June 12–13
- July 27–28
- August 28–29
- September 18–19
- October 20–21
- November 6–7 and November 30–December 1
- December 21–22
2. Reality in 2026 and 2027: Will candidates have limited test dates?
In response to this landmark information, USMLE has issued an official confirmation to reassure candidates: Candidates at this time continue to register for exam appointments through the Prometric system according to the normal process.
The tightening and limiting of exam dates under the new category is expected to only officially begin to apply from 2028.
Therefore, those of you who have a plan to review and prepare for the exam in 2026 or 2027 absolutely do not need to panic or rush to change your personal route just because of this announcement.
3. The core reason behind the sudden change from USMLE
The official reason given by this organization revolves around the problem of system security:
- Maximize the level of security for official exam questions.
- Thoroughly limit the situation where exam questions are illegally memorized, reproduced and shared by candidates.
- Minimize the risk that some groups of candidates will gain an unfair competitive advantage from accessing exam questions first.
- Protect the credibility, reliability, and core value of global USMLE score results.
When a question bank is used continuously over a long period of time and candidates have the right to take the exam on any day throughout the year, the risk of exam content being leaked and passed on to the next generation is very high. Concentrating the entire exam on certain days of the year will help USMLE control the exam source much more closely and safely.
4. The profound impact of the new USMLE exam schedule system on IMGs
The change in the USMLE exam schedule from 2028 will turn roadmap planning into a vital, decisive skill for international doctors (IMGs).
Currently, if you feel that you are not really ready before the exam day, you can completely flexibly reschedule the exam to a few weeks later and proactively find another empty exam slot on Prometric. However, once the number of exam days is strictly limited, the game will completely change:
- One delay is no longer a matter of weeks: If you miss a test date, you may have to wait months for the next test session to reopen.
- Competition pressure for convenient exam slots: Exam slots at geographically convenient locations will evaporate faster than ever.
- Backward time calculation problem for Step 2 CK: The Step 2 CK exam time must be accurately calculated backward from the ERAS application submission milestone and the waiting time to receive the score report, with absolutely no errors allowed.
- Time constraints for Step 3: The Step 3 exam schedule needs to be closely balanced with the residency rotation schedule, hospital duty schedule, and deadlines related to visa or fellowship.
- Wide-scale impact: Medical schools and clinical training programs will also have to proactively adjust curriculum (program framework) as well as students’ timelines to suit the new system.
Especially, for those who intend to take Step 2 CK close to the ERAS application season, the old-fashioned review strategy: “Just focus on studying first, when you feel ready to take the exam, then go online to find a test date” will become an extremely risky gamble. You may have prepared very well in terms of knowledge, but the system no longer has any test dates that fit your timeline.
The terms have not yet been finalized
The USMLE Council also noted that the current 2028 schedule only stops at the Planned calendar level. The number of test days will likely remain the same, but each specific test date can still be adjusted.
A number of important operational technical details are still being developed and perfected, including:
- How long will the Eligibility period last?
- Official registration process and how to reserve your exam spot.
- Strict rules regarding rescheduling or canceling exam dates.
- The official opening time of the schedule portal for candidates to choose their slots.
- A detailed list of Prometric testing centers has been added.
- Technical handling plan when candidates fail the exam and need to retake the exam.
- How to arrange separate test schedules for candidates who need special support (testing accommodations).
Further detailed information and updates are expected to be announced periodically by USMLE on a quarterly basis.
Conclusion
Although this historic change has not directly affected those entering the exam room in the period 2026 – 2027, it is a clear message that shows: USMLE is shifting strongly from an exam with a flexible schedule to a model that requires extremely serious discipline and long-term planning from very early on.
Starting from 2028, on the journey to practice as a doctor in the US, being well prepared in terms of knowledge is definitely not enough. You are also required to:
- Prepare at the right time.
- Sign up at the right time.
- And keep your test date consistent with your overall residency strategy.
In the USMLE journey, knowledge determines whether you pass the exam or not. But planning at the right time determines whether you can enter the Match season in time or not.
