Comprehensive Review of USMLE (CRU): March 2011 Update

Updated information on the Comprehensive Review of USMLE (CRU) is available. Access the March 2011 update on the USMLE website.

CRU was initiated in 2004. The goal of this review was to determine whether the mission and purpose of USMLE are effectively and efficiently supported by the current design, structure, and format of the USMLE. This review resulted in recommendations for changes. In 2009, the proposed changes were approved by the USMLE parent organizations, the National Board of Medical Examiners (NBME) and the Federation of State Medical Boards of the United States, Inc. (FSMB). Research, planning, and implementation of the changes have begun.

Changes resulting from CRU are planned for all USMLE Steps and Step Components. These changes may affect both content and item formats. As changes are implemented, the orientation and practice materials available on the USMLE website at may be updated to reflect these changes.

If you plan to take USMLE examinations, you should monitor the USMLE and ECFMG websites for the latest information on changes related to CRU. Comprehensive information on CRU is available on the USMLE website at
