You might want to try to post in the tribes forum which may see more traffic. But, overall (as you're probably aware) the best option for public school in Chicago has to be a charter school. So, look around and see what is available and what your child can get in to. (They're very competitive.) Chicago also has a Waldorf High School at http://chicagowaldorf.org/
and there are a few grade schools around the suburbs.
There are a lot of pre-schools and kindergartens, but less of the higher grades from what I've seen.
Good luck in your search. Let us know if you've found anything.
