Is your child a Davidson Young Scholar?
If so, they can help to advocate for your child with the schools. They were extremely helpful in our daughter's case.
Speaking from experience I can tell you first hand that if your child is >MG there will be no perfect school out there - it just becomes a matter of stacking up the pros and cons on each side of the scale for each choice and checking for the alternative that is skewed the least sub-optimally.
Redo the above periodically.
