Not all religious parents who homeschool will have bad outcomes, but it's by far the largest demographic of people who fail to actually educate their children. As for your last statement: in most states there's no oversight. Sure, parents have to file a curriculum that gets reviewed and approved. Parents jump through that hoop by downloading a curriculum and mailing it in. There's nobody checking that they actually follow any of that curriculum. There's no state-run testing as a check and balance.
