<p>By that standard, the most moral institution would be a well-run state penitentiary.</p>
<p>Seriously, at virtually any of the most selective, prestigious universities, your definition of “moral” will tend to be rejected. On the other hand, at most of those schools, people will be too busy studying to be partying and having sex 24/7.</p>
<p>As you move down the selectivity and competitiveness scale, chances are, students will tend to have more idle time to do these things. I have read that the biggest “drinking” schools tend to be (a) rural (b) southern (c) unattractive to Asian students. So if you want a relatively selective school with less partying (I don’t know about the sex), perhaps aim for a northern/western urban school with many Asian students. Maybe Carnegie Mellon?</p>
<p>Or you can pick a “religious” school like Liberty University, Bob Jones, or Patrick Henry. Less politically right wing (but still socially conservative) would be Goshen College (a rather respected Mennonite college).</p>
<p>A couple of the guides (I do not recall which ones) do attempt to identify where schools sit on the liberal/conservative spectrum. But keep in mind that “top” schools, even ones that attract many relatively conservative students, tend to put a premium on personal freedom. </p>
<p>At many schools, though, you can ask to live in a “substance-free” dorm.</p>
