homeschooling in TN is easy-peasy. You have two options a) register with the school that you are homeschooling. or b) sign up with an umbrella school.
If you do a) you are required to do standardized testing in grades 3,5,7, and every year in high school.
If you do b) it is up to the umbrella school if you will do the above testing or not. Some interpret the law to include kids in an umbrella school, others do not. One umbrella school that I know of that does NOT test is gateway. Mine does, but I like standardized tests. They help me as a teacher.
Cumpulsory school age is 6. I am not sure if the top age is 16 or 17 because I don't have any that age.
There are no subjects that you are required to teach, but you do have to teach 180 days per year 4 hours per day.
That is about it. It is a VERY FRIENDLY place to homeschool with LOTS of homeschooling activites, and co-ops, and tutorials, sports teams, scouts troops, music opportunities... the rec centers, the ymca, the gymnastics places etc... all of them have classes just for homeschoolers. 4-H has homeschool classes, too. Basically, anything you can do in public or private school, you can do as a homeschooler here if you want to. Also, we have a state lottery here, so going to college can be a LOT cheaper here, too, and yes, homeschoolers get those scholarships, too.
Anything else you need to know? Actually we have some opportunities we are considering, and the MOST difficult part of moving AWAY is that there is SUCH support for homeschooling here. It is hard to leave that behind.
