If you are preparing for the United States Medical Licensing Examination (USMLE), the testing landscape has changed significantly.

USMLE Step 1 Review
1. Updated Test Delivery Software and Block Restructuring
The USMLE rolled out an updated testing interface across Step 1, Step 2 CK, and Step 3. The new platform features a modern design, enhanced keyboard navigation, an updated settings menu, and per-image contrast adjustments for easier visual interpretation during the exam.
While the total question count, content domains, scoring standards, and overall test-day duration remain identical, block structures were overhauled across all three exams:
- Step 3 (Launched March 10, 2026): Moved to 12 shorter blocks of 30 minutes each.
- Step 2 CK (Launched May 7, 2026): Transitioned to 16 blocks of 30 minutes, each containing up to 20 items (previously 8 blocks of 60 minutes).
- Step 1 (Launched May 14, 2026): Transitioned to 14 blocks of 30 minutes, each containing up to 20 items (previously 7 blocks of 60 minutes).
- Break & Tutorial Structure: The optional tutorial was reduced to 5 minutes, adjusting minimum total break time to 55 minutes. Remember that once a 30-minute block closes, you cannot re-enter or alter previous responses.
2. Transition to Designated Testing Dates (Planned for January 2029)
To reinforce security standards and safeguard score validity, the USMLE program is planning a transition away from the flexible, year-round “on-demand” testing model.
- Target Rollout: January 2029 (adjusted from the initial 2028 target timeframe).
- New Administration Model: Across all three Step exams combined, testing will take place across a total of 45 designated testing days per year.
- Exclusive Access: The program plans to partner with expanded testing centers to reserve seats exclusively for USMLE examinees during these specified windows.
If you are planning your timeline for 2029 or beyond, factor in fixed testing windows rather than relying on on-demand availability.
3. Completed Service and Portal Transitions
Registration workflows and candidate portals were consolidated to streamline administrative operations:
- International Medical Graduates (IMGs): As of January 12, 2026, all USMLE services formerly managed through ECFMG / MyIntealth shifted completely to the Federation of State Medical Boards (FSMB).
- U.S. Medical Graduates (Step 3): As of January 26, 2026, Step 3 registration and candidate services for U.S. graduates moved under the National Board of Medical Examiners (NBME) via the MyUSMLE Portal.
