Crystal,
The problem you note for the vocational/career schools is very real. You are right -- they are judged on their success rate in placing students on the job, and that puts them in a difficult position when it comes to students with disabilities. But the problem you describe for the recent graduate is even MORE troubling, as it suggests that he would be more than capable of doing a good job and is losing out on opportunities because of the bias others have shown to finding a way to facilitate his employment. You might try having him contact the Job Accommodation Network at http://askjan.org. Their purpose is to help consumers with disabilities to make that leap into the world of employment.
