It is illegal in the country I live in. Foreigners get around it somehow, but nationals would get pulled up, I think.
I don't agree either. And I say this as an experienced teacher. Unless they've literally written a comprehensive long term curriculum plan (reception to Y6/y11), medium plan (yearly/termly), how can they possibly write short term plans (weekly/monthly)? Or cover what would be covered academically in school?
Obviously there are companies that provide this, and do termly assessments to check the kid is age-expected etc . But as far as I know, most don't go for . Obviously, SEN/MH needs aside - clearly the 'system' is brutally failing particular kids with specific needs in every single way, which is awful and should not be happening.
But that's just academics. There's a lot to be said for being with the same group of 30 kids for 6 years or longer, friends, not friends, different races, cultures, beliefs, behaviour, socio-economic background and how to cohesively live as a member of a micro society.
I am confident I could teach the academics necessary to be above age-expected to my kids (possibly in fewer than 2 or 3 hours a day), but could never replicate the micro society aspect, even by meeting up with home ed groups three times a week.
I've just happened to meet a bunch of 'unschoolers' / 'world schoolers'..... don't even get me started. Those poor kids. It should be considered neglect (especially when the 10 year old is begging to go to school!).
