I find this to be very hard in my technical school, there are some courses that it would be very difficult to do with a physical disability, but more importantly I find that some individuals are psychologically unable to accomplish these feats either and not necessarily because of a disability but sheer laziness. I think its so individualized as to what a person is capable of. That said, I teach phlebotomy and had an individual sign up for course who was legally blind. He did well, but was unable to find work.
