I'm with the others. I'd be hesitant to go with the private school b/c it sounds like he might not be up to producing work at the level he'd need to feel like he fit in academically with the other kids. We've had this same struggle with out HG ADD child. She gets concepts beautifully and has the ability in some ways to work well ahead, but her 2e-ness prevents that from fully happening.
We did have luck, however, with getting her to perform more on par with her potential by going for subject acceleration in one subject, math, in 5th, which she has gotten more and more successful at maintaining after two years of that type of acceleration.
The only worry I'd have with the charter you mention is the word "strict." My dd11 is attending a middle school that is very structured and which would not have worked for my HG+ non-ADD child, but I don't think that I'd call it "strict." It may be semantics, but we do have two charters local to me that are frequently referred to as strict and that often tends to mean "rigid" in relation to those schools.
I totally sympathize with your comment about needing the structure for the ADD but not for the giftedness. We've had that too. Dd11 was highly frustrated with the drill approach particularly in language arts in 6th grade. It helped with her weaknesses (structure, attention to detail) but was mind numbing for her strengths (depth, abstract thinking).
Do you have a feel as to whether the charter's strictness carries over into their curriculum approach or if it is just in terms of their discipline/not letting kids get away with stuff?
