Florida State has a decent program as well as a College of Education. If your daughter's goal is secondary teaching in Florida, they may have a combined program that results in an MEd and certification in 5 years or something similar.
Unless she's also planning graduate study in Classics, Ancient History, or Classical Archaeology, you don't have to worry too much about getting into a top program such as Michigan, Harvard or Berkeley. Target universities where she can work on the teaching component simultaneously with the Classics material.
If you can swing it, any kind of summer intensive program will be a huge leg up at the college level - many high schools, while they do a good job with the basics, are pretty weak on grammar and sight reading skills. If your high school academic counselors can't or won't dig out the information, just ask here - there are quite a few of us Classics types lurking amid all the engineers.
Incidentally, there's a more or less comprehensive list of Latin (and a few Greek) teaching jobs maintained here:
