I recently read this very well-written book by Ellen Winner and found it gave an excellent overview of the challenges and nuances of gifted children. It's useful for parents to be widely educated on all sorts of areas that relate to children and education and this book will give you food for thought and consideration, even if it doesn't relate specifically to your situation. One point that particularly struck me was the reflection on how some parents never find a system they are happy with and continually move the children or choose to homeschool.
