USMLE Designated Testing Dates Delayed to January 2029: What IMGs Should Plan

The USMLE programme has pushed back its biggest scheduling change in decades. In June 2026 it announced that the three Step examinations would move from on-demand testing to a "Designated Testing Dates" model from 2028, with the exams administered on a total of about 45 days a year. On 6 August 2026 the programme said the transition will instead take place during January 2029, after feedback from medical schools and examinees. For international medical graduates (IMGs), including the large Pakistani cohort, the extra year matters, and so does understanding the model that is coming.

What the model is

Today an examinee books Step 1, Step 2 CK or Step 3 on almost any working day at a Prometric centre, subject to seat availability. Under the designated-dates model, each Step will be offered only in set windows, and the programme has said that together the three Steps will be administered over roughly 45 days each year. The exam content and format are not part of this change; the May 2026 software update (shorter blocks, same questions) is a separate matter already in force.

Why the programme says it is doing this

The June announcement framed the change as exam security: fewer testing days make secure content easier to control and reduce the chance that exposed items are reproduced or shared, which the programme says could unfairly affect examinees' results. The August update added that the model brings "additional safeguards that are designed to reduce security risks and promote fairness for examinees" and will support standardisation and the value of scores used for US licensure.

Why it was delayed

The programme says the January 2029 date gives schools more time to review and adjust policies and curricula that are tied to USMLE performance or completion. It also announced practical steps: a Designated Testing Dates Implementation Panel including educators, US and international examinees, state medical boards and members of the public; a resource on expected testing-appointment capacity by region, based on historical volumes; and continuing work on application, scheduling and exam-day logistics.

What is still unknown

• The exact calendar: how the 45 days are split between Steps, and whether windows differ by region.
• Capacity at Prometric centres outside the United States, including Pakistan, during the windows.
• Fees, rescheduling rules and what happens to eligibility periods that straddle a window.

Until the programme publishes those details, any specific window dates circulating on social media are guesses.

What this means for Pakistani IMGs

1. Anyone planning to test before the end of 2028 is unaffected. On-demand scheduling continues. If your Step 1 or Step 2 CK is within reach, do not wait for the new system; book under the current one.
2. Students graduating in 2029 or later should expect to plan around windows. Final-year schedules, house job dates and Match timelines will need to fit the published calendar. Build in a buffer: a missed window could mean months, not days.
3. Seat competition will rise around each window. Pakistan's Prometric capacity is finite; early booking inside a window will matter more than it does today.
4. Watch the official hub. The programme has an information hub for the change and has promised updates there; third-party summaries, including this one, will be out of date the moment a calendar is published.

What has not changed

ECFMG certification requirements, the Step 1 pass/fail outcome, the Step 2 CK score, and the May 2026 software format are all unaffected. Since January 2026 the FSMB handles USMLE services for IMGs while ECFMG decides certification eligibility, and that arrangement continues. FAME's USMLE Step 1 and Step 2 resources will carry the published window calendar once it exists.
