So, tl;dr:

The inclusion model I’d like to see is one that is committed to both:

to educate all kids together, ie in the same building(s), by staff that is responsible for all, in physical proximity wherever that is possible without compromising the education for anyone

And to educate everyone in their proximal zone of development, with the understanding that this will result in outcomes that will radically differ across the student body.

I would hope that once you had a system committed to both, one would be able to navigate all the compromises, indivual solutions, mistakes and new attempts cheerfully and eventually successfully.

Getting off my soapbox now!
