I recently graduated from Ithaca College with a BA in Drama and a focus in Stage Management. Like JenniferS said, the BA gives you a lot of latitude within the department to do many different things (act, direct, write plays, stage manage, etc.) as well as allowing you to focus on one area.
Within that area of focus, there are also many different opportunities. In my four years, I ASM'd and SM'd mainstage shows, student directed shows, shows off-campus, shows that were performed out doors and moved around campus as well as a show in Spanish. So, as you can see, if you're willing to put yourself out there you can really get a variety of experience for your educational dollar.
I did nothing but SM for my four years, but I also know a lot of BA Drama majors who directed, acted and wrote as well. It all depends on what you want to do there.
If you would like a graduate's perspective as well as a freshman's (what could be better than looking back AND looking forward?) feel free to PM me as well.
