I wouldn't suggest that the idea of holding all children to the same achievement standard is the same as teaching them using the same methods. There's no question that different children learn better or worse in certain environments. I've seen my own kids respond entirely differently to different kinds of instruction and discipline.

What I took away from the Charter schools approach (and granted, I'm no expert) is that with reduced student to teacher ratios and more in-class time coupled with targeted learning practices to the student lead to success where otherwise little was seen.

For the autistic child, there's no question they need to be engaged differently than other kids. I could be wrong, but children so diagnosed get addressed in the special education program which, on the face of it, seems like the right thing to do.
