"a good option would also be to take some OU courses on your own weaknesses so you're better rounded and prepared (i.e. study some education/youth work + some science (if arty) or some arts (if sciency)."
Goodness no need for any of that either.....do it if you want to by all means, but there isn't a need to do it-and I'd see it as time wasted when your child could actually be being home educating!
I didn't have time for any of that! We found out that HE was a legal viable option one day, and the deregistration letter went in for all three children the very next school day!
There's a very interesting article on home education by the Frasier Institute -looking at outcomes, where the parent hasn't got a good education themselves here
""Poorly educated parents who choose to teach their children at home produce better academic results for their children than public schools do. One study we reviewed found that students taught at home by mothers who never finished high school scored a full 55 percentage points higher than public school students from families with comparable education levels."
I sincerely believe after all these years and meeting all of these HE families, online and hundreds now in real life, that what you actually need to begin with, is an interest in and enthusiasm for your child's education.
Home educating families become really good at facilitating their children's education.
