Hmm, not sure if I would put it that simply.
It's definitely not treated as an "exceptional" case, and there multiple different options on how it can be handled, depending on the level of special care required by the kid and their academic capability (and disruptiveness to classmates). E.g. On the one hand there are non/low-communicative autistic children that attend "Gymnasium" (our highest "tier" in the school system) with the help of a dedicated care person. On the other hand it can also happen that an autistic child will attend a "special needs" school, where the day-to-day can look far less "normal", and it will likely be hard to attain a normal job as an adult.
