My wife and I homeschool our kids in Tennessee. We love it and so far it is working great for our family. As required by state law we are registered, we have an appropriate curriculum, and we maintain records. Every year we pay to have our children take the national standardized tests, and our kids test well above the local and national averages.
In our local home-school group we have two families that have a parent who is a public school teacher. We know some families that do a fantastic job home-schooling, and unfortunately we also know some that do a less than stellar job. The same thing applies with public schools, some are good, others not so great.
We know the people involved in the home-school political asylum court case. In Germany, the government has taken kids away from parents who home-schooled. The family fled Germany to avoid that fate. I'm very glad to hear that this family has won in the courts and will be allowed to stay in the US and home-school their children.
