I'd agree with a PP who said that school is an unhealthy form of socialisation. In the rest of the world, how often do you get shut in an environment five days a week with people whose only thing in common is that they were born in the same academic year as you?
OP, there's an interesting documentary on Amazon called Class Dismissed. It's American, but very interesting!
Do you live in an area with a lot of other home educators? There are groups that meet up, sometimes do classes together, or go on days out to things of interest, or just to socialise! Have a look on social media to see if you can find a home education group near to your areas. I seem to have found myself in an area with quite an active HE community, so they have sessions at a forest school, a gymnastics club, and even aerial silks class!
You can buy ready-made curriculums online, or you can come up with lessons by yourself.
I'm an ex-primary school teacher, and don't think that being in a group of 30 is good for children. The only ones that really stand out are the noisy ones, or those who have difficulties in managing their behaviours. What about the shy ones, or the bright ones, who get lost in this mix?
I now work for a college. The only students that I've come across who were truly happy with their 4-16 educations were the HE ones, which says a lot! I would, however, recommend getting them GCSEs at 16, otherwise they might get put on the lowest-level college courses (I've questioned this, but I'm not in charge of that department), despite their intelligence. Some colleges also run GCSE classes for home educated children, usually just in English, maths and possibly a language, so that might be something to consider when your LO is a lot older.
I'm not a home educator, but it would be my first choice if I had school-aged children.
Good luck, OP!
