In an effort to ease the challenges of applying to medical school, application services have been created to allow applicants to submit just one primary application, regardless of the number of medical schools to which they apply. The most widely used, the American Medical College Application Service® (AMCAS®), was created by the Association of American Medical Colleges (AAMC). Most Doctor of Medicine (MD) programs in the United States use AMCAS as the primary application method for entering classes. For students interested in osteopathic medical programs, the American Association of Colleges of Osteopathic Medicine (AACOM) created the American Association of Colleges of Osteopathic Medicine Application Service (AACOMAS). And for students interested in attending a public medical school in the state of Texas, the University of Texas System worked with the Texas Health Education Service to develop the Texas Medical and Dental Schools Application Service (TMDSAS).

Because all three application services deliver the required medical school application materials and information, all three are accepted by Ross University School of Medicine (RUSM), which is an MD program located on the Caribbean island of Barbados.


The AMCAS Applicant Guide provides a thorough account of the entire AMCAS medical school application process, but we’ll go through some highlights here. Applying with AMCAS includes:

Students should ensure that all information on their AMCAS application is correct. After submission, only certain changes are allowed. Applicants should also monitor their AAMC med school application after it is submitted. Even if all required information is included, processing the application can take up to eight weeks. Applicants should check the status of the AAMC application throughout the process.

Students should keep in mind that AMCAS is not a free service. Applicants pay a flat fee for the AMCAS application and the first medical school designation. Applicants then pay a fee for each additional medical school to which they apply. The AAMC Fee Assistance Program (FAP) may help qualifying applicants with these costs.


Applying through AACOMAS is very similar to AMCAS, but it is geared toward osteopathic medical programs. Check out the AACOMAS Quick Start Guide for recommendations on when to get started, application fees and waivers, and help with such things as personal statements, official transcripts, letters of evaluation, and keeping track of your application after it is submitted. Students who are applying or have applied to osteopathic programs may also submit their AACOMAS application to the MD program at RUSM.


TMDSAS is meant for public medical schools in the state of Texas, but the application process is basically the same as AMCAS and AACOMAS. The TMDSAS Application Handbook has all the details and more. Students applying to medical programs in Texas may also use TMDSAS to apply to RUSM.

Students should note that application service deadlines are unique to each medical school. Usually, students can access their AMCAS, AACOMAS, or TMDSAS applications beginning the first week of May and then start submitting in June for the following year’s autumn medical school class. Because RUSM has three start dates per year (January, May, and September), there are no application deadlines, but applicants must choose a preferred starting date.

Students should also note that AMCAS, AACOMAS, and TMDSAS are only primary applications. Secondary applications, or school-specific applications, accompany most primary applications. At RUSM, students may apply through an application service, but it is not a requirement. Students may also apply directly through the RUSM application.

Before beginning any medical school application, check out RUSM’s full list of medical school admission requirements. There is a lot to prepare, so get started early. Do your homework, gather your materials, and when you’re ready, see all the ways you can apply to RUSM. It may be the first step toward a rewarding medical career.

In 2020, 91% of RUSM students passed the initial step of the United States Medical Licensing Examination® (USMLE®) on the first attempt. And in 2022-2023, results show yet another strong year for RUSM with a 98% first-time residency attainment rate* thus far. Located on the island of Barbados and with a network of more than 15,000 alumni, RUSM is one of the largest providers of doctors for the U.S. healthcare system. RUSM graduates practice in all 50 states and in Puerto Rico.

*First time residency attainment rate is the percent of students attaining a 2023-24 residency position out of all graduates or expected graduates in 2022-23 who were active applicants in the 2023 NRMP match or who attained a residency position outside the NRMP match.
