zzz I am a vet of ASD mostly, and some other stuff, starting with own relative 15+ years ago.
In all that time, parents' gut instinct keeps turning out to be right.
In the early days, I tended to think that what had been such a massive benefit to my relatives would work well for other DCs who presented in a similar way, but ASD turned out to be much more complex and subtle.
Parents turned out to be right over and over, with indie experts, when available, explaining and analysing.
Sure, there have been times when parents have some experience, or piece of information, or breakdown in a relationship has skewed the parental judgement, but it is in the 'less than 10%' bracket.
So Adri the smart money says you are probably right, but zzz may have a point - your past experience of seeing some kids being plonked in front workstations for the benefit of teachers/LA rather than the kids themselves might, just possibly, (maybe less than 10%!!), be impacting on your view for your DC.
I ma sure you are smart enough to realise if that could be happening, and to test the impact of workstation-education-options at home.
Good Luck
