Big news
For event-based testing, USMLE Step 1 and Step 2 CK will not include unscored pretest items, resulting in a slightly shorter exam. The Step 1 event test examinations will consist of 200 items, and the Step 2 CK event test will consist of 240 items.
Unscored pretest items are commonly used in high-stakes examinations to obtain statistics on item performance before those items are included for actual scoring, and they are an important part of the exam development process. The exclusion of unscored pretest items for event-based testing is a temporary solution to make event-based testing at medical schools feasible. Exams administered by Prometric at Prometric test centers or regional testing centers (phase one) will continue to include unscored pretest items.
We greatly appreciate the collaboration with the medical schools involved in phase one and phase two of our plans. We will continue to provide details and frequent updates about our testing recovery efforts
