I personally raised two guide dogs and have seen first hand how they benefit those who receive them.    

The first guide dog I raised helped a blind boy go to a regular high school (a first for that school, but strongly supported by a visionary and very compassionate Principal, who took this on without hesitation). That boy has graduated and is off to law school at a University that has never, until now, accepted a blind student. By the way, he had graduated with high honors from high school. I also have seen first hand how autistic children interact with their dogs. It is a thing of beauty! Forget the idea of a crutch, anyone who knows anything about autism and the challenges it imposes on the child and family, fully understand the huge level of support required and the benefits of a dog in these situations. Sounds like those who have made the decision to prevent this boy from having the support of his dog at school, need to educate themselves further on the benefits of guide dogs.
