COMAT Clinical Subjects  |  Administration

Delivery Options

  • In-Person Proctored
  • Remote-Proctored
  • Self-Proctored

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 as long as minimum technology requirements are met.

The NBOME requires that a COMAT coordinator be assigned by the COM to oversee all administrative tasks.

Please Note: The delivery platform (COMAT Secure Browser) 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.
