note this part of the article:
However, Estrada warned that Common Core “threatens the foundation of homeschooling.” Standardized tests, such as the SAT and ACT, are beginning to be aligned to Common Core standards, and this sets a worrisome precedent for homeschooling. School districts are also becoming more emboldened to coerce homeschoolers to follow their education standards. Westfield, New Jersey saw a school district push homeschoolers to follow Common Core. Estrada’s organization, HSLDA, stepped in and Westfield backed off its outrageous demand. Additionally, there are student privacy concerns with Common Core, when student information is logged into a database.
Even with those problems affecting what a parent can do at home (UNBELIEVABLE!!) the parent has the opportunity to choose better materials as a supplement on their own. Besides that, by being at home, they're spared of the out-of-control discipline issues and the constant indoctrination.
It will take only another generation or two before there's no cultural memory of what it takes to preserve a real education which produces independent thinking, moral, academically excellent students.
