I was there in April (?) of this year and we saw a special needs boy participate in the Jedi Training Academy. I'm not sure what the boy had but my guess would be Cerebral Palsy. It seemed like he couldn't speak well, and had severe mobility issues with mild uncontrollable movements but could walk, but nothing too spastic or extreme and he was understanding and following Jedi instructions very well, I would say he was about 11 or 12.
Anyway, his mother(?) stayed with him the entire time, he was paired with Darth Maul and after he fought the crowd cheered him. It was actually very moving and there were several teary on lookers.
I would say speak to a Jedi castmember and talk to them about it. I did see the mother speak to one of the Jedi helpers after he had been selected, who helped out and would check in often throughout the show.
