The 3 Main Medical School Applications Every Premed Must Know

Mar 31, 2021

There are three stages to the medical school application process: primary applications, secondary applications, and interviews. The primary application is the initial application a medical school receives. Secondary applications (a.k.a. supplemental applications) are school-specific applications sent to an applicant after the primary application has been approved. Finally, the interview is when you visit the school and get the chance to talk to the faculty directly. 

All U.S. medical schools use 1 of 3 application services: AMCAS, TMDSAS, and AAMCOMAS. Each medical school program only uses one application service. Knowing the difference between these three main medical school application services prior to applying can help you prepare for the different components of each application. In this article, we will discuss each of these medical school application services and the differences between them.
