<p>So that I don’t have to waste six words each time I say “The College of Arts and Sciences” can I use CAS instead (are they used to seeing that?), or will that be seen as lazy, colloquial, unprofessional, etc.?</p>
<p>if you parenthesize CAS afterward the first time, you can formally say CAS afterward. It’s done in newspapers all the time. In other words, the first time say “The College of Arts and Sciences (CAS),” and afterward simply say CAS.</p>
