Cstone says it well. However, not all ADHD is correctly diagnosed, and some is simply bad behavior developed in the home. As such, the 'training' required may be better applied to the parent, before attempting to modify the child. I think Cstone hinted at that, but I do want to emphasize it. Yes, schools are not asylums, and they are not hospitals of any style. We closed those some 50 years ago, along with the 'county poor farms'. Perhaps a mistake, but they are now gone, while schools are expected to fill the gap and give relief to the parents. Having had experience with non-comunicative autism, and Asperger Syndrome at the other end of the spectrum, you have my sympathy. That said, you might want to try home schooling, but with an occasional visiting 'teacher' added to the mix. Discipline with love and encouragement may be much better than the disinterest experienced in the typical large classroom of a typically unqualified school; if any place or any person can ever be 'qualified' in this matter.
