When I went to college oh-so-many years ago, I was in the Honors program and the Honors dorm. I thought that everyone in the Honors dorm would also be in the Honors program, as it was presented as one of the perks of the program. However, I was mistaken. Of the 4 girls in my room, only two of us were Honors students. The 3rd girl was placed because she and the other Honors girl requested to be roommates. (They were from the same hometown. Girl #3 ended up being my favorite roommate.) I have no idea how Girl #4 ended up being placed. She was not an honors student, but she *was* crazy. If she made the kind of threats today that she did then, I'm sure she'd be expelled at minimum, and possibly even arrested. Back then, they just said "I'm sure she doesn't really MEAN that, and it's not nice of the 3 of you to gang up on her like this." when we reported it to the RA, Resident Director, and Student life. It was a nightmare.
My son applied to the Honors program at his college but did not get accepted. However, you don't have to be in the Honors program to be in the Honors dorm/community. Actual Honors students get priority, but if there's extra room, anybody who requests the Honors LLC can get in. I have also heard that the Honors LLC is usually in one of the nicest dorms. I urged my son to request it, and I think he was planning to, but his roommate was not on board. Both roommates have to make the same LLC requests, so he did not choose honors. I'd rather him live with someone he knows isn't crazy than "chance it," even for the Honors dorm.
Anyway, I hope it all works out splendidly for everyone... but it is very possible that everyone in the Honors dorm will *not* be an Honors student. That has been my experience anyway.
