Registration & Scheduling

Changes to your Name and Status

In order to take a COMLEX-USA examination, your name on your registration form and the valid government-issued photo ID presented at the testing center must match.

If your name has changed, download and complete a Name Change Request Form and include a copy of the supporting document noting the name change (e.g., marriage license, divorce decree, court document, naturalization document). Documentation can be scanned or emailed to clientservices@nbome.org. Name changes must be made no later than five business days before the scheduled test. If possible, submit the name change form and documentation before registering for an examination.

Log in to your online account to update your mailing address, email address, and phone numbers, located in the in the “Student Information” section under the “My Account” tab.

If you transferred medical schools, you must contact the Dean’s office at your old and new school and request that they forward the information to clientservices@nbome.org.

Retaking An Exam

Candidates may not retake any level of COMLEX-USA to improve their scores or for any purpose other than to pass a previously failed examination. For candidates who have failed an examination, they may retake the examination a maximum of four times in any 12-month period.

Six Attempt Limit

Candidates taking COMLEX-USA examinations are limited to a total of six attempts for each examination.

The only consideration for an exception to this policy for one additional attempt beyond the six-attempt limit is at the explicit request of a Medical Licensing Agency.

For NBOME to waive the limitation of a maximum of six attempts for any COMLEX-USA examination, candidates are required to obtain a written petition for waiver from a Medical Licensing Agency.

Effective July 1, 2022, candidates taking COMLEX-USA examinations will be limited to a total of four (4) attempts for each examination (COMLEX-USA Level 1, Level 2-CE, Level 2-PE and Level 3), including but not limited to all attempts prior to July 1, 2022. After June 30, 2022, no candidate will be allowed to take any examination more than four (4) times without obtaining approval from the NBOME.
