Homeschooling In Your State
Some states, like my home state of Michigan, require no notice or registration at all.
"There are no requirements to notify, seek approval, test, file forms, or have any certain teacher qualifications. The burden is on the state to prove that the parents are not teaching their children."
In other states, like North Carolina, the requirements are more stringent though they only apply to children of compulsory schooling age which is between your 7th and 16th birthday.
You can visit the HSLDA website and find information on your state.
