Due to scheduled maintenance on Friday, December 20 from 7 pm – 8 pm EST, the NBOME portal may experience a potential outage. We apologize for any inconvenience.
COMAT Administration
Quick Links
The NBOME will partner with your school or college of osteopathic medicine (COM) to tailor COMAT administration to meet its specific needs.
COMAT is delivered on a secure browser and can be delivered on the web via PC/Mac or on an iPad using the eCOMAT app. COMAT also allows for same-day scheduling for any delivery option. This functionality provides flexibility for multiple-site delivery, making off-campus administration easy if minimum technology requirements are met.
The NBOME requires that the COM assign a COMAT coordinator to oversee all administrative tasks.
Delivery Options
COMAT Clinical
- In-Person Proctored
- Remote-Proctored
- Self-Proctored
COMAT FBS
- In-Person Proctored
- Self-Proctored
Please Note: The delivery platform does not support the use of touch screen monitors, as they could impact some exam functionality. To ensure the assessment performs correctly, please use a keyboard and mouse to navigate through the exam.
