PAS, how old is he? I was assuming he's around 5 since it sounded like they were recommending Kindergarten for him?

Also what does IU stand for? I think this is your school district? Have you tried finding a privately moderated social skills group? I had looked into them last summer and found several local to us, but ultimately found DD was well-served by her school program which includes just kids on the spectrum.

FWIW just as a note, the ability to focus on a topic of interest does not contradict ADHD. This is called "hyperfocus". I often think that hyperfocus is one of DD's more advantageous skills--and can be useful to her if she can learn to manage it.
