Read most of the posts and wanted to respond, as the parent of a special needs child. FB Gwynn is no longer (and hasn't been for many years) a school for special needs. It's now a place for "at risk" children. My daughter attended Gwynn until they decided it was better to farm the kids out to "all inclusive" schools.
The thing about Life Skills classes is that although they are now in "inclusive" settings, for the most part, they are pretty much stuck in a classroom, excluded from contact with the other students except at lunch. If they are higher functioning, sometimes they leave to attend a "regular" class, but return to their LS room after. They receive their speech/occupational/physical therapy in the LS classroom. They've got a "buddy" or two who come in and "interact" with them or do things like go to PE with them, etc. depending on the special needs student's level of function. While in the LS classroom, depending on their level, they learn life skills to help them be independent, but more importantly at the HS level, they may go out into the community and have "jobs".
Sounds to me like Westlake doesn't have a LS class with that sort of setting.
My daughter went to Stone, which had a GREAT LS classroom and I hated to have her leave it when we moved. She had several "buddies" and even 10 years later, people who went to school with her will come up and say hello to her. Wherever this young man goes, I'm sure the same will be true. I can tell that the mother was touched by how nice the other kids were to her son at the dance, but most assuredly the same sort of thing will happen wherever he goes, and he'll adapt.
Personally, (and I don't know the whole story after reading her letter) I think the mother ought to want her son in the Life Skills class that best fits his needs, rather than wanting him to be with friends. His Life Skills class will prepare him for adulthood - whereas his friends will go off to college and pretty much leave him behind as he lags further and further behind them. 30 minutes isn't a long busride.
