Because the 'local education officials' are doing such a good job of it eh? Look at the stats for home schooled - that always test much higher than the public schools, where illiteracy is rampant. Sooo... why again?
I’m just saying it doesn’t sound like there is any form of assessment to ensure that unschooled students are making academic progress. If the state cannot verify that these parents are providing adequate instruction or even basic levels of literacy and numeracy. nevermind quality educational outcomes, the family should be given the support and accountability they need to step up their efforts.
