Most residency candidates know that their lives will be made easier if they apply in only one specialty, but some apply to a competitive field with a backup, and others are still deciding between two at the time of ERAS submission.
Here are some clarifications about what ERAS offers that will help you apply in two specialties:
1) Different personal statements can be assigned to different programs. This means you can assign your ob/gyn essay to ob/gyn programs and your internal medicine (IM) statement to IM residencies.
2) Different letters of recommendation (LORs) can be assigned to different residency programs as well. (A maximum of four letters may be assigned to each program.)
You will have only one MyERAS application. It will go to all of your programs. (Note that if you list your membership in multiple ob/gyn organizations, that will be viewed by your IM readers as well and might make them question your commitment to IM.)
If you are thinking of applying in three specialties, I’d say don’t. Navigating the application and interview process while showing commitment to each field could be miserable. If you’re at three, take a moment for some reflection, and pare your list to one or two.
