It really depends on the school. I did my undergraduate education at a major university that had an affiliated with a mainstream ("middle-of-the-road) protestant religion and had it not been for the large chapel in the middle of the campus, you never would have known it. While they recognized the importance of spirituality, they were very open to all religious beliefs and did not "push" any one view.
However, I have known other schools
that definitely preached it's religious views and included a lot of coursework focusing on their particular beliefs..
I have also worked in 2 Catholic hospitals with very different perspectives -- one much more "liberal" than the other.
As an aetheist, I think I am fairly sensitive to such practices and it is something I look at when I choose a school or job. There is no hard and fast rule that applies to all institutions. You have to consider the culture of each place separately.
