Except DCD isn't a delay, it's more along the lines of a neurological motor disorder, or learning disability involving motor skills. So if he does actually have that, all you'd need to do is get medical documentation from someone like a neurologist or neuropsych (and have that person state he should have accommodations in school and therapy). Of course if he scored well on the BOT2, that might be a problem. DS's neuropsych gave him the Grooved Pegboard test for fine motor, and he did horrible, like well under the first percentile. That might be similar to the dexterity section of the BOT though. DS is very slow on any motor test that is timed. See if you can get the BOT results and what he scored for just the sections that are timed. DS's scores kind of average out because he's very high on some things like visual perception and balance, bringing his overall scores up. There are other tests involving motor skills as well. The school gave him a different test for gross motor and he scored lower than the BOT2.
