There is a lot of discussion in the RIT unofficial facebook family page about the difficulty of finding co-ops. There are many resources on campus, but it is ultimately up to the student to find a co-op. Many families speak of their students sending out 75+ resumes, then receiving offers at the last minute. It seems fairly standard.
RIT does have a fairly robust support network for students with documented learning disabilities, as well as a program specifically for students on the autism spectrum. On this page you can see the types of support that they offer students - http://www.rit.edu/academicaffairs/advising/student-resources
