We basically need to stick with public schools because private schools are under no obligation to educate my DS. He could easily pass an entrance exam for any private school, but I can't live day to day not knowing if I'll get that phone call saying he has to leave because they "can't meet his needs." It happened in preschool, believe it or not, and I'll never quite get over it. Can't put DS through that again.

The schools we're looking at out of state are just regular public schools. Some districts and schools are just more progressive and compassionate than others (like the school in Boston you mention). I'll see if I can find an educational consultant. I've never heard of that before. We do have experience with special education advocates ($$$), but I'm not sure if that's the same thing.
