There is a very well made documentary showing a great model of inclusion. Film makers shadowed Peter, a young boy with Down's Syndrome from grade 3 through high school graduation. It is on HBO Family, showing again this Thursday. I recommend it for anyone interested in learning more about inclusion.
To elaborate, the inclusion model is what is impressive. That is not to say that the boy and his family do not come across challenges in the placement. But, he is able to graduate with his peers, as part of the community that he will be living in, and not in a sequestered "special" community.
