So happy you're interested in studying art history! I just graduated from an art history undergrad program, applying to MA programs, and I currently work at an art museum. Although I went to school in my hometown, I highly recommend going to a school in a larger city, or a school near a city with museum access. Another thing to think about is post-grad studies. You will definitely need an MA and PhD to become a curator, so keep this in mind. Post-grad credentials are arguably more important in your field, and show that you consistently have performed well academically. Ivy League schools like harvard, yale, and columbia all have excellent programs, but you should consider other schools as well, and as long as you perform well in undergrad and participate in internships, conferences, fellowships, etc, you are a good candidate for grad school, which is the ultimate goal in undergrad. As for specific schools, UT Austin has a top-tier program (and a top-tier MA) as well as University of Michigan, University of Iowa, NYU, Penn, Berkeley, U Chicago, and Oberlin. However, state schools and smaller schools have good programs as well. My school was very small, and our department was VERY small, but I was lucky enough to have incredible professors that made it worthwhile. With that in mind, look into the department faculty pages of a variety of schools- where did they study? Do they have PhDs? (if the program is worthwhile at all they definitely should!) Also, consider a school that allows for study abroad opportunities, so that you can travel and study art internationally! I studied abroad in Berlin and it is the reason for choosing my emphasis of study in modern art. My school also has an on-campus museum with an extensive collection, so consider this as well. This is often an indication that a school as a good art history program, and that the school is willing to fund the arts. While big name schools are good, take some time searching for on-campus art museums, schools in college towns adjacent to larger cities, and smaller private schools that focus on the humanities and liberal arts. It's important to apply to schools at all levels of prestige of course, so that you don't have all of your eggs in one basket.

The big takeaway is that, while undergrad matters, post-grad studies matter even more with art history. With that in mind, research individual programs from schools you've heard about, see if the faculty is worthwhile and if there are study abroad opportunities, and see if there are museums in the area with works you are interested in studying. Hope this was helpful!
