An update.

Heard this from another 2e parent who is a trusted source, though I may have missed some of the nuances since the info is secondhand...the art teacher that DS fought with until we pulled him has stated she treats the disabled kids in our program (a magnate program for profoundly gifted children) is if they were mentally disabled - she made an analogy to Downs Syndrome.

This is not a good thing, but explains a lot. In any case, we've already decided that we'll proactively homeschool him in art next year if she is going to be the teacher.
