20 years ago when I homeschooled here in TN you had to have a 4 year college degree..
I had a friend who was an RN who had completed a 3 year program and was disqualified from teaching her children because of that rule..
I remember I had to fill in forms each year giving a schedule and list of all subjects I was going to teach ...
other states had different rules...
some states did not allow homeschooling at all in those days..
You will need to check with your own state school system..
I hate when there are so many restrictions!
I was blessed to be able to live in AZ where we were left alone and we had school choice!
