If I were any of those things then I expect my parents would send me to a specialist school, not try to include me in mainstream education. Children who do have that level of disability are rare.
That would be lovely but specialist provision is very hard to come by. My DD is able to speak but can’t communicate her needs - she has complex processing difficulties due to early trauma. She can’t tell when she’s hungry, thirsty or tired, she experiences most bodily sensations as anxiety, She has sensory processing issues and has significant hearing loss. She gets very overwhelmed in a normal classroom setting which, so far, shows itself in her hiding in the classroom or taking herself off to the toilets, which are quiet and she can gather her thoughts. She’s also significantly learning delayed.
All of this still doesn’t mean she’ll automatically get a place in a specialist provision - at the moment her primary school are able to make enough adjustments for her that it’s just about manageable, but there are still difficulties. In mainstream high school I can absolutely see her lashing out when she’s not able to cope with constantly changing classroom, changing expectations of different teachers, remembering what she needs for what class, busy corridors and the noise levels. At that point she’ll no doubt be labelled as a difficult or violent kid, which she isn’t.
The lack of decent specialist provision for children like my DD is appalling, she has the right to an education but mainstream school would be disastrous for her. It’s not simply a matter of requesting she be placed elsewhere though.
