I recommend kage_ar’s recommendations.
I would also suggest, because he is so young, that you consider your local community (junior) college until he is at least 18, maybe even 19, provided they are accredited by your accreditation board (
North Central) and meet your state requirements for general education subjects. You will be able to keep an eye on him, as he’ll live at home. As he is so young, and not accustomed to being out in the world, this would be a nice transition.
You will save a ton of money, as where he takes his general ed. subjects,
as long as they are accredited, just doesn’t matter. He can even do the two year course, then take an associate degree with him to one of the better Catholic schools listed in the
Newman Guide. Some 4-year schools offer AA and AS students who transfer a full ride, based on the fact that AA/As students have already achieved a degree.
My husband is a freelance philosophy professor with a decided conservative bent. He teaches all over the Chicago area. Students pay $450-$700 a semester hour, $1350-$2100 per course
before books, with 3 semester hours being the usual credit of a course, to take his courses in Intro to Philosophy and Ethics, if they take his couses in a private school. Tuition to take the same courses at a junior college- with the same texts, same study aids and
same instructor- cost about $110 a semester hour, or $330 for the course
before books. New books run anywhere from $50-$200
per course. Used books are not always obtainable.
He finds many Catholic students from Catholic high schools at the junior colleges, even his own nephews upon occasion.
As I am privvy to too much information on Catholic colleges in the Chicago area, I can’t say too much. I can’t, and he can’t, recommend any of the Catholic universities at which he teaches except University of St. Francis in Joliet. It is literally in the shadow of St. Raymond Cathedral, is accessible around town by bike, and has been working on improving its orthodoxy as well as its safety over the past five years- before the Virginia Tech and NIU tragedies. Oh- and the neighborhood has some of the best pizza in Illinois

.
We have also visited Loras College, which has a nice, stable, orthodox Catholic community. It is in Iowa.
But if you are looking for an authentic, orthodox Catholic college that is accredtied, must be sleep-away from home environment, where he will be safe to some degree from underage drinking and harming his faith, I think you are shipping him to Steubenville, Ohio; Warner, New Hamphire; Naples, Florida; Belmont, NC; or Santa Paula, CA.
