I don't know that the program exists anymore, but if you can find information about a school that had Disney College Program ambassadors, that would be a good place to start. These are students who completed a CP and are now company reps to recruit others.
The best way to get information though is to understand what they want to study, and speak with the appropriate adviser. Since they are the ones who will help with schedule planning, they will understand best how to either remain a student during the CP or take a semester off without delaying graduation (since I assume those are what you are looking for)
Larger state schools will probably have a system already in place just because of the number of students in different life stages going through the institution.
Don't discount smaller schools either. I went to a very small (500 student) university and spoke with my adviser early on about what would be necessary to graduate on time while taking a semester off for a different internship. We sat down and worked out a potential 8 semester plan that he then went over and made adjustments to based on when classes were offered. I didn't end up taking the internship, but because of this planning I was able to graduate a semester early.
The biggest hurdle you may run into (since planning around a semester/year is relatively easy) is things like internship credits (not every school considers the DCP an appropriate internship) and financial aid (Schools may not grant aid to part time students, and 6 months without attending so many classes will start the repayment timeline, something to watch for if doing the DCP for a full year)
While you are looking at colleges, I would be sure to focus on what your child wants to study before looking at extras like the DCP. Once you've found schools that offer something similar to what they are interested in, then start going after those extras. And also remember that just because something hasn't been done before doesn't mean it can't be done now. Someone can always pioneer an initiative so that others can benefit in the future
