I started answering just as I saw eksmama01 respond. In general I agree there are many states (including mine) with extremely lax homeschool laws. All one has to do is take attendance and take one test per year (and no need to report results). Any there are many not teaching well and/or teaching incorrect things.
That said, I started homeschooling my youngest child mid-year this year, and will homeschool one more year until he's in high school when he will return to public school. The middle school we were at had gotten simply awful. Terrible staff turnover, months upon months with no teachers for some classes, when they would finally find a replacement teacher, they were never anywhere close to as good as the ones that left. Some kids didn't have ELA or science teachers for most of a year. Not to mention the bullying. The only work given was repetitive busy work. Not only was my child not learning anything, he was bored out of his mind, miserable, and extremely depressed. When we would watch a 5-10 minute science video at home once we started homeschooling, he told me they would spend a week covering that same few minutes of material in his science class. I'm not a teacher, I still work a full time job, and I don't profess to know what I'm doing. But, I'm absolutely certain he is getting more out of it than he was at school. And he's so much happier.
The high school we'll go to seems much better with staffing, and I've already talked to the principal about making sure we receive credit for HS level classes we're already doing. Anyway, just to say, homeschooling is not ALL bad; it's a lifeline for some of us that needed to get our kids out of a bad situation, in states and areas where public education funding and support is being methodically and intentionally eroded.
