What defines a "religious" school?

<p>Have any of you noted that while it is possible to use CollegeMatchmaker and other similar search engines to find colleges and universities with particular religious affiliations, it is NOT possible to search for those with NONE?</p>

<p>Would-be applicants looking for a completely secular environment have a very great challenge ahead of them as even public (and presumably secular) institutions can still have highly religious student bodies as a result of the specific demographics of the region served by that college or university.</p>
