Application Instructions

The American Association of Colleges of Osteopathic Medicine Application Service (AACOMAS) simplifies the process of applying to osteopathic medicine programs.

You start by selecting the programs you wish to apply to, then you submit one application that includes all necessary materials. Once received by AACOMAS, your application and materials go through a verification process before being transmitted to all of your selected programs.
