How Step 2 CK is set up

For exams taken on or after May 7, 2026, USMLE describes Step 2 CK as a one-day examination divided into sixteen 30-minute blocks and administered in one 9-hour testing session, with no more than 20 questions per block and a minimum of 55 minutes of break time. Before that date it was eight 60-minute blocks. Details change, so confirm them on the official USMLE Step 2 CK page.

USMLE says Step 2 CK assesses an examinee’s ability to apply medical knowledge, skills, and understanding of clinical science essential for the provision of patient care under supervision.

The Step 2 CK passing standard

USMLE changed the Step 2 CK passing standard on the three-digit score scale from 214 to 218, effective July 1, 2025 (USMLE announcement).

Attempt limits to know before you sit the exam

You may not take the same Step more than three times within a 12-month period.
Your fourth attempt must be at least 12 months after your first attempt at that examination and at least six months after your most recent attempt.
If you have attempted a Step four or more times, including incomplete attempts, and have not passed, you are ineligible to apply for any Step.
If you pass a Step, you are not allowed to retake it, except to comply with a time limit imposed by a U.S. medical licensing authority.
