Marsha,
Well... I was with you right up to the last sentence! The whole point is that students with disabilities WHO HAVE GRADUATED FROM YOUR PROGRAM are no more or less likely to "be successful" than any other student. If they are not able to function with reasonable accommodation while in school, then they don't graduate. If they DO function well with reasonable accommodations in school, there is no reason to believe they will be less likely to be successful when they get out than any other student!
