Sorry to be so school specific, but with a freshman-to-be at Purdue, that school has my attention right now. Anyway, details are still very sketchy but apparently the campus president announced earlier today on some talk show that all 40,000 Purdue students who wish to be on campus in a month and a half will have to test negative for Covid before going on campus.

As I said, details are still coming. But it sounds like the students have to do it at their own expense. And I'll assume it has to be within a certain time table but I'm not sure what that time table is yet.

I don't believe any other school has announced this yet, but it wouldn't surprise me if this becomes the norm. Many private or smaller schools might be able to test all of their students once they get to the campus (similar to what some athletic departments are doing with their athletes), but testing all students is another deal altogether. Especially when you're talking about the bigger state schools.
