Good to hear your team is on top of it. One other area that might be worth investigating, perhaps in a couple of years, is dental. I have also seen some students with severe cross-bites and other orthodontic issues improve significantly in articulation after orthodontia. (Not a dental professional, though, just my anecodotal observations, and feedback I've heard from SLPs.) For example, a (2e, actually) student who had both orthodontic issues and motor dyspraxias, with extremely intractable articulation issues, who saw noticeable functional improvement with many years of OT, and with orthodontia (speech therapy, too, but that didn't really spur as much progress alone as with the other therapies).
