I disagree with some of the advice in this thread. While some LACs are indeed very good for classics, the powerhouse programs are at universities, and the top programs offer a breadth and depth of classes unmatched by any LAC except Bryn Mawr. Because classics is such an unpopular subject these days, you’ll find that classical language courses are inevitably quite small (<20 students) even at very large universities. Moreover, it is only universities that offer related ancient languages, both Indo-European (e.g. Sanskrit, Old Persian, and Hittite) and other (e.g. ancient Egyptian). I would especially emphasize universities if she’d be entering college with a background in one or especially both of the languages.
As for anthropology programs, they have no more overlap with classics than other liberal arts disciplines like art history, philosophy, religion, economics, and political science.
It will be difficult to beat the top British options, if you’re from the UK as your name implies – either in cost or quality. Oxford has the world’s best classics program by a wide margin, of course, but there’s also Cambridge, UCL, Bristol, Birmingham, Edinburgh, Exeter, St Andrews, KCL, Glasgow, Liverpool, etc…all of which stack up quite well against the best American programs.
I’ve written about classics programs extensively over the years; post #3 links to pretty much everything I have to say on the subject, except I oddly forgot Princeton in my Tier 1 of university classics programs. I’ll quote the relevant parts here, making a few edits:
