Homeschooling is the way to go. I did this with my son after he finished the 5th grade. He was one of the brighter students, and would get in trouble a lot as he finished his work quickly and then wanted to talk out of boredom. They lean towards teaching towards the lowest common denominator so they can appear more successful, which handicaps children who aren't slower.

I also didn't appreciate all the social mindsets they seemed to focus on that were contrary to reality. My son did learn not to listen to them about violence is never the answer. He was a punching bag his last year for half the year. Some kid who was older (had flunked despite the work being watered down for folks just like him) would hit him daily. I kept urging my son to fight back, only way to stop it. He finally had enough and did. The principles face was priceless when I let her know my son might be in trouble at school, but he was getting ice cream on the way home. That he wasn't sent to her school to be a punching bag and if the school couldn't stop that, then my son had permission to see that it stopped.

Given the mandated reporter laws here, coupled with so many cases of abuse, its not smart to have that much overreach into ones home under the justification that there are a handful of cases that are in need of such tactics.
