<p>One way to find this out is to take a look at each university’s code of conduct in the student handbook.</p>
<p>Biola: <a href=“Student Life Blog - Biola University”>Student Life Blog - Biola University;
Pepperdine: <a href=“http://seaver.pepperdine.edu/studentlife/handbook/”>http://seaver.pepperdine.edu/studentlife/handbook/</a>
Azusa Pacific: <a href=“http://www.apu.edu/judicialaffairs/handbook/”>http://www.apu.edu/judicialaffairs/handbook/</a>
Westmont: <a href=“http://www.westmont.edu/_student_life/student_handbook/studentconduct-process.html”>http://www.westmont.edu/_student_life/student_handbook/studentconduct-process.html</a></p>
<p>Biola’s handbook is pretty conservative. Their code of conduct prohibits “sexual activity outside of a marriage between husband and wife,” which includes premarital, extramarital, and same-sex relationships; they also have a specific prohibition on same-sex relationships separate from that clause. Possessing pornography, smoking (on or off campus), and participation in ‘student organizations not recognized by the university’ are all also prohibited. They also have an extensive [treatment</a> of other topics](<a href=“http://studentlife.biola.edu/handbook/policies-procedure/academic-appeals/"]treatment”>Student Life Blog - Biola University) like dancing (choreographed dancing is allowed; free dancing and college sponsored dances are not), entertainment (no rated R movies), and dress (no short shorts, halter tops, short skirts, strapless shirts, etc.) You’re also required to go to 30 chapels per semester, which is about 2 per week for a standard semester.</p>
<p>Azusa has a prohibition on same-sex romantic relationships and on premarital/extramarital sexual contact (and they only recognize marriage between a man and a woman). Students are not allowed to drink or do drugs on or off campus, and they cannot possess porn. Full-time students must attend chapel 3 times a week, with no exceptions.</p>
<p>Pepperdine does not allow drinking on campus or at university-sponsored event, but students who are of age can drink off-campus. Their statement on sexual relationships is crafted in such a way to make it clear that they don’t approve, but don’t necessarily prohibit it. It’s a little bit murky - they say that students can face sanctions for sexual misconduct, but refuse to say outright whether premarital/extramarital sex counts. They also have an LGBT support group on campus, although it is not a positive group per se (they stress that they don’t condone same-sex relationships, but that they feel LGBT students can benefit from having a place in which they can share questions and struggles and say that they will sanction individuals who harass LGBT students).</p>
<p>Westmont makes it pretty clear: “The college does not condone practices that Scripture forbids. Such activities include but are not limited to occult practices, drunkenness, theft, profanity, and dishonesty. Such activities also include sexual relations outside of marriage and homosexual practice. Westmont further recognizes that Scripture condemns “sins of the spirit” such as covetousness, jealousy, pride, and lust. By their very nature, these sins are more difficult to discern. Because they lie at the heart of the relationship between the individual and God they are of central concern to the Westmont community.”</p>
<p>I don’t have any direct experiences with these schools, but given people I know and what I’ve heard about them, I would say Pepperdine is the most lenient of the four, followed by Azusa Pacific. Biola is a pretty conservative campus. I don’t know anything about Westmont.</p>
