> Because they have some kind of accreditation body that monitors and approves the schools with established standards and approved/documented practices, whereas homeschool does not? There are "accredited" homeschool programs, and the "accreditation" means probably about as much as it does for "accredited" private schools, many of whom don't even bother. Elsewhere in the comments I mentioned the Baltimore public school system, where clearly whatever "accreditation" it has is completely and utterly worthless. Heck, even my ABET accredited university, although overall of high quality, had a few teachers that taught me nothing at all and who had no checks on their failure to teach.
