COMAT Administration

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.
