Registration & Scheduling

Set up your NBOME account

Before you can register for and schedule an COMLEX-USA examination, you will need to set up your personal NBOME password-protected online account in the NBOME Client Registration System (CRS):

NOTE: Your personal data is treated by the NBOME as confidential. It will not be disclosed to any individual or entity without written, signed consent by you or an order of a court of competent jurisdiction.

NBOME Account

An NBOME Account is Required for Registration of Exams & Services.

Account access enables the necessary examination management and registration tools. Once an account is established, users are able to:

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 and emailed to clientservices@nbome.org or faxed to 773-714-0606. 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.

Request for Rescheduling Fee Waiver for COMLEX-USA Examinations


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.

Six Attempt Limit

Candidates are limited to total of six attempts for each exam, including but not limited to all attempts made before July 1, 2016. Candidates may take (including retakes) the COMLEX-USA Level 1, Level 2-CE, or Level 3 examination up to four times in any 12-month period. Review the Bulletin of Information for details.

When rescheduling, be sure to allow adequate time to retake the examination before your school’s graduation deadline, and keep in mind the time required for remediation and rescheduling. Also check the Score Release Information (typically 4–6 weeks). Remember that passing COMLEX-USA is a requirement not only for medical school graduation, but for starting a postgraduate medical education or residency training program.

Candidates should check the policies of your college of osteopathic medicine for its retake guidelines, which may differ from those of the NBOME. You will need the approval of your dean or residency program director to retake the examination; however, approval to retake a COMLEX-USA examination by a dean or residency program director will not override NBOME retake policy.
