You can get a copy of the syllabi for various courses ( and this is a great thing to do). You can also see if the school teaches Latin, Classics, Ancient Greek and has upper level English classes that are classic in nature ( Shakespearean lit for example). Many schools will cover all bases. So while they might have Irish literature, they might also have African poetry or other courses.
There are many schools which are out there. Most list courses on their web sites.
