I am about to start college, so I haven't gotten in to meet professors or anything like that, but I can tell you what we have done thus far!
When I was looking, I looked within driving distance of home (meaning about 10 hours for the longest drive, 7 for the next-longest.) I didn't really intend to leave the state without a scholarship, but I knew that I would be moving out of home for sure. We didn't worry about being close to CF centers or anything really related to CF with my original search process. I had a major in mind and I looked for top programs in that major, as well as schools that offered a lot of variety so that if I did change my mind, I would have other options that would also get me a job.
I applied to 6 schools; 4 out of state, 2 in state, 3 that I would consider back ups, and 3 that I knew I had a good shot of getting in, but didn't anticipate any scholarships. I approached applying just like all my friends did, for the most part.
Once I knew a bit more about where I had been accepted and where I would probably be going, I started looking more seriously as far as doctors. Even in February (3 months before the deadline) I had it down to 2 schools. The one I picked is a 7 hour drive. I guess some time around April we discussed with my doctor here what he wanted to do for college. In June we drove up and met the CF team at my university, and they seem very good and very much in line with my own doctor. We started talking to disability services in April. I got approved about a month ago. They have set me up in a private apartment so that I don't have to worry about other people's germs and can have my own space.
I guess my biggest pieces of advice:
-Don't worry about it too much right now. If your CFer isn't at all independent, maybe steer towards places closer to home, and certainly keep cost in mind, but there are scholarships (for CF kids!) so don't count out a school due to cost until you have to.
-When you have made a decision, contact disability services. If you wait to long, they will be unable to assist you with your housing needs; most schools close housing May 15, and they need to know about your issue before that. In addition, at my school there are only monthly meetings to get approved by DS, so if I'd waited I would've had major problems.
-Talk about what you want in a dorm room. If your CFer will be too shy to do their treatments in front of others or if you are worried about germs as I was, think about a private room. I know that I get sick when I spend time with sick people, so I didn't want to put myself in that type of situation, not to mention worrying about meds being moved and such. At first I was very much against having a roommate until I really thought about what it would mean and how it could potentially be a big issue. Also, the traditional hall-style dorm isn't for me. Leaving your room and remembering your key every time you have to wash a neb or get a drink is a pain. I didn't want to do it. You need to at least have an idea of what you want when you approach DS.
-Keep your doctors in the loop and see what they think. They have dealt with this before and may think of things you don't know about.
-If your kid may be going far away, visit the CF team. If I had hated my team, there is one other nearby, but even if there weren't, it probably wouldn't have been a deal-breaker for the school. That being said, they need to know that you're coming so if there's an issue, you're an established patient.
Ok I'll stop now - let me know if you have any questions!
