One of the Big Shots in our system has, for some years now, run a program for autistic and developmentally delayed kids at a school in Denver.
I've only been there once, as a guest judge for a promotional exam, so I can't judge it's impact personally. But I met a number of kids that day who, by all reports, have really blossomed during the course of their training.
We don't have a specific program, but we currently have two autistic kids in our beginner class, one of whom is really starting to come out of his shell.
