Comment: Ask your self if you want your child sitting next to a kid who hits, spits, defecates in their pants and then tosses at the nearest person. Tips their desk over, blaming some one else, throws chairs to harm others, destroys your child's projects, screams nonstop for a hour. 

These violent children do not belong in a normal classroom. Most will never make the "transition" to jobs. Autism is forever, FAS is forever. They will end up in jail, or some other confinement. At best a low wage job that won't cover the cost of their meds.

Go to YouTube and watch some 'autism outburst' clips, and then decide if you want your child sitting next to a kid like that. If I knew my child was to be a "role model" (and did any one ask the parent if they want their child to be a role model?)  to a kid that messed up I would pull them out to another classroom.  Put those kids in their own school with those who have the skills to deal with them. Save every one money, time and pain.
