Home schoolers...

... Finally, I find it interesting that no one has addressed the fact that individual parents may be able to address a specific discipline or two in regards to curriculum, but there is no way that individual parents can address all curriculum at the high school level. Sorry, parents simply do no have the time or curricular knowledge...

Actually Parents have more time and some are more qualified and have a better motivation for success. They are not bound by your curriculum and can easily surpass it. The problem is with the marginal child, who will just be passed along without any useful knowledge or discipline. He or she then finds himself or herself in the real world without the tools to have a good life.
