My husband is a teacher as well & refuses to send our kids to school. Homeschooling is not easy and I am tempted to at least send our oldest back to school, but he sees what goes on both academically and socially and will not subject our kids to that.
He feels like a rebel or missionary within the system, but curriculum and requirements are set by others so there is only so much that teachers can do.
The one good thing I will say about inner city schools is that they are so desperate for teachers who can keep the kids in the rooms and not running through the halls vandalizing stuff is that they leave curriculum pretty much up to the teacher. In English, anyway. I choose the books and movies we cover. I have to teach them the “skills” the District wants, but that’s fine. As long as I get to choose the books and movies.
