Oh I can totally relate to your post. My DS7 is a definite squirmy worm and is not the perfect student in the classroom. He is willing to make his own form of entertainment if he is not engaged at school. His teacher admitted she can't even reach him academically in the classroom, but loves to focus on his fidgety issues. Again - he'll sit still for hours for the right book or lego project. He's definitely not one of the top behavioral problems in the class by any means. I do tend to agree that he's not the ideal candidate for radical acceleration in a regular classroom although that is what he desperately needs.
Anyway - we are looking at homeschooling for fall. Our public school is very poorly equipped to deal with kids that don't fit a certain mold. GT kids at our school who are teacher pleasers seem to fare at least somewhat better. And we're another family that never thought we'd be homeschoolers. We're not Christian or conservative. You may just put feelers out in your area to see what kind of outlets and organizations are available for homeschoolers.
