Hi Ohiomom,
Welcome!
I hope someone here has experience with these schools.
The interesting thing about school for the gifted is that two kids who are equally gifted can have completely different experiences at the same school.
I've found that the some key things that makes a school work for my family are:
1) The school understands LOG, level of Giftedness.
2) The school understands, and has options for, kids with 'spikey profiles' that is a wide variation between their strengths and weaknesses, even if the weakness are still above average.
3) Flexibility
best wishes,
Grinity
