Here in California, a lot of parents who homeschool their children do so by filing what's known as an R4 Affadavit with the state. This form does not give parents permission to homeschool, but rather to establish a private school. Now it looks as though the state's Department of Education is trying to crack down on homeschooling by informing anyone who requests an R4 form that establishment of a private school for the purpose of homeschooling by uncredentialed teachers is illegal. I've requested a written copy of this advisement, and am curious to see what the state DOE is basing its position on.
