We have attended Northwestern CTD classes at Quest in the summer and the kids have loved it. Our current school started offering CTD classes, so we'll be doing there from now on.
I have a friend 3rd grader attends Quest and she loves it. She's moderately gifted.
Another friend had two kids at Quest and didn't feel her kids were being challenged enough. She moved them to public school gifted program in Palatine and thinks the education is much better.
A friend with 2 profoundly gifted kids who attended Science and Arts Academy, but she said the differentiation that sounded good in theory didn't play out in reality.
We visited DaVinci twice. It looks like a good school, but we couldn't get over how small the building and campus was.
We have 2 PGs and wanted to send them to Avery Coonley in Downer's Grove, but it's too far from our house. We currently send our kids to Elgin Academy and supplement with Stanford EPGY classes and CTD classes, but my kids are still under challenged and bored. We're not sure what we'll be doing next year.
As for public schools, I've heard the best feedback from friends in the Park Ridge and Schaumburg gifted schools.
Hope this helps and best of luck!
