It might be helpful if you could let us know more specifics about how you think your ds is impacted by DCD and also remind us how old he is (and I realize you probably don't really know much about the DCD impacts yet since you weren't expecting it as a diagnosis!). FWIW, our ds' primary diagnosis is DCD, and his dysgraphia is due to issues related to DCD. We haven't needed many accommodations for his DCD but it's helped to be able to explain it to teachers etc who usually haven't ever heard of it and tend to mistake some of it's impact as non-motivation etc.
When we were in public school, our advocate suggested we ask for adaptive PE for our ds, but we skipped out into private school and there is no option for adaptive PE. DS has difficulties with catching/throwing balls, kicking balls, moving at anything faster than the speed of a glacier etc... so he's happier with individual activities over team sports, but sticking with the team/ball sports in PE with all the NT kids has actually been really good for him (imo)... and has helped improve his muscle strength and coordination.
The one thing he can't do at this point in time is open a lock-type locker, so he's allowed to not have a lock on his locker.
The rest of his accommodations are primarily for dysgraphic things - keyboards all written work, ok to use voice-to-text, extended time on tests + uses a computer for essay questions on tests, is allowed to write answers in the test booklet instead of on bubble sheet, things like that.
One other area that we believe is dyspraxia-related and is challenging for our ds is getting his thoughts into words quickly enough to be able to participate in rapid-fire classroom discussions (the other kids are *much* quicker)... and he was being graded on participation earlier this year based on how many times he contributed... so we had to address that with his teacher.
One other thing that only relates to school in a small way is that our ds feels full after not eating very much (and we've been told that can be related to dyspraxia)... so he'll think he's eaten enough at a meal and then feel like he's starving 1-2 hours later. So we ask that he be allowed to have a snack when/if he needs one during the day, and he keeps extra granola bars in his backpack in case he gets hungry suddenly.
And oops... I kept using "DCD" and "dyspraxia" as one and the same. They might not be technically the same, but they are as far as I know basically the same disorder. DCD is the official diagnosis ds has from his neuropsych eval.
Gotta run - hope some of that helps!
