While the national debate about education is about coming up with a single national curriculum rather than fifty state versions, the debate that is not happening is about homeschool rules. Each state has its own rules and regulations about homeschooling. I think it's fascinating that these questions are too hot for any politician to handle. It's also interesting how dramatically different the Maryland homeschool rules are from say Alabama homeschooling rules.
If I've understood correctly, in Maryland, the families are required to meet with the board of education twice during the school year for a review of the program. As I've heard, while this seems scary, they actually send out very positive supportive well-informed people who seem to have a constructive relationship with the families.
In contrast, in Alabama, homeschooling is basically not allowed under that name unless the parent is a certified teacher. Families must join these bogus "cover schools" which are basically private schools organized to provide an umbrella or cover for homeschoolers.
For homeschooling in Florida, there are cover schools but many homeschoolers take the option of notifying their school board that they intend to homeschool and then fulfill the annual requirement of getting their child reviewed by a certified teacher or other formal annual review.
