The homeskoolers in Arkansas who advocate this property tax credit don't understand what's coming. (Would that surprise anyone here who knows about the Duggars?) If it passes, it will open the door to much more state regulation of homeschoolers as a condition of getting the credit, assuming that the Arkansas government works like the federal or any other state government would. In case these people have never noticed, governments tend to assume they have first claim on your money, and if they let you keep some of it through a credit, that is the same as cutting you a check. And accepting a credit, let alone a real check, means accepting government conditions including regulations.
That's why the school voucher initiative failed in California some years back: teachers' unions threatened to sue to require private and parochial schools that accepted voucher money to meet
all the federal and state regulations that public schools had to meet. Several private and parochial schools there said in response that they would therefore not accept voucher money if the initiative passed, which effectively killed its support.
I have long had a problem with homeskoolers for the reasons the rest of you have mentioned. If Moo and Duh can't add two numbers without a calculator, can't write a coherent sentence, and believe the world was literally created in seven days about 5,000 years ago, how—and
what—the heck are they going to "teach" their kyds at home? But in some instances I have seen and known of personally, children are being brutally abused at home, or obvious mental or emotional issues are not being properly treated, because the child is "homeschooled" and does not have normal contact with public school personnel or other adults who could intervene.
One example was a coworker's 12-year-old homeskooled neighbor girl, who was seldom seen outside her house and seemed abnormally withdrawn and shy around others. We've all seen news stories about nasty long-term parental abuse of children, and often neighbors in such instances will similarly say that
they seldom saw the kids outside the family's house. The coworker, who had experience in such issues, said the girl displayed the classic symptoms of sexual abuse at home. Because she passed annual tests from the local school system affirming that she was performing at her grade level, authorities' hands were tied without direct evidence of abuse. But as the coworker pointed out, what's to stop the parents from doing the school system tests for her if she simply takes them at home without outside supervision? Great, more nookie for daddy!
(Even worse, my state has available to religious nuts a total religious-based exemption from any schooling—even homeskooling. Few people seem to use this, but it's on the books. At least one example is known of brutal abuse leading to the death of the child by people using this total exemption.)
In a few RARE cases, a truly gifted child may do best with homeschooling by enlightened, educated parents when the school system fails to give that child the educational opportunities it should get, and most public school systems fail miserably with such children. But such cases are relatively few. People here are right to be suspicious of most homeskooling.
