I think you need to delve into what Jewish life is like at these schools. If she’s not into Hillel, is she planning to go Greek? For kids who strongly identity as Jewish culturally it’s good to know the make up of Greek Jewish life. At some schools the percentage of Jews who go Greek is vastly more than the general school population. And at some , especially in the south , the percentage Jewish girls are relegated to one or two sororities. For this kind of insight she needs to be In touch with others students. Are there others that she knows from your hometown, or friends of friends she could talk to?
