<p>FWIW: When I toured Georgetown (another catholic/jesuit school) I asked the tour guide in private whether my agnostic/atheist daughter would feel out of place. She assured me that there were lots of atheists/agnostics on campus, and that the campus truly valued diversity in all its forms. And in fact, looking around the campus there was plenty of diversity of all sorts. </p>
<p>She then went on to say something like “Now, Notre Dame, I would not recommend for such a person. She would not be comfortable there”.</p>
<p>I realize that the OP’s sister is not so concerned about the religion but it is partly the result of strong religious affiliation that the university has difficulty enlisting a diverse student body.</p>
