I don’t go along with the “fully funded” part.
Perhaps there should be private schools for these children, where the teachers have received special training.
Any cost in private schooling for special needs children should be tax deductible, however.
Special needs kids can have wide abilities and disabilities.
That’s why they are special needs.
My daughter with a brain injury has speech & reading issues, but she is gifted at math. She is also very well-behaved in the classroom.
