WOW.. This is upsetting! Colleges should be able to WANT to give you a good education, even if it means getting you an interpreter. If i were you, I would copy off some proofs from the ADA site about having an interpreter for schools, etc. That's what I did when I needed to get an qualified interpreter.. I'm pretty good at researching stuff.
take a look at this link from NAD (National Association of the Deaf) ::
State and Local Colleges and Universities | National Association of the Deaf
Maybe you can find something on there. But what I found out that section 504 also goes with college education. And I've been scanning through their education statements or however you would want to call it. I wrote this down in my little notebook but copied off of their site. Here's what I wrote down:
*Failure to provide a qualified interpreter or other auxiliary aids or services for a deaf or hard of hearing student/parent under these circumstances would be described as a discriminatory practice.
*The office for civil rights also determined that sign language interpreters permits deaf people to participate meaningfully in Federally assisted programs. It has also ruled that public school systems (as well for colleges) must give access to extracurricular programs and must give access when they offer services to parents as well as to students.
i don't know if this is much but I hope it helps
