Oh yay another home education bashing thread!
As a parent your job is to facilitate learning and ensure your child receives a suitable education whether this be by sending them to school or by home educating.
My son was unable to attend school for most of years 8 and 9 and during that time he recieved some out of school tuition which really is minimal.
I home educated him through gcscs. I didn't 'teach'. My job was to facilitate learning, encourage and motivate. We used a wealth of resources including online courses and resourses. We worked together to understand the syllabus and mark schemes and to mark past papers. He taught himself art, attended a couple of clubs, used the home gym and walked the dog. He learned to type. We did PHSE, politics, law, current affairs etc through daily discussions about anything and everything. He watched you tube videos on topics that interested him. He played computer games and dabbled with coding and blender. He learned to cook and budget. None of this involved me doing any of what you would call 'teaching'. The process was fluid and flexible.
He sat 5 gcses in total (2 in year 10 and 3 in year 11) which is what he needed to get onto his chosen level 3 course at college. He got decent grades, went to college and never had a day off sick. He found his people and is now living away from home at uni.
He was able to sit the exams at his old school as an external candidate. When he went to pick up his second lot of gcse results with his old cohort in year 11, his maths teacher was surprised to find that he had sat maths in year 10 and got a 7 and didn't have a tutor. When receiving out of school tuition just a year before he had been predicted a 4.
A couple of his friends (who appeared academically similar in year 7) sat the full complement of gcses in school but got much worse grades which I think happens when you spread yourself too thin and have to sit a bazillion exams in just a few short weeks. The system we have doesn't suit everyone. Having a goal, appropriate resources, being able to work at exactly the right level and having 1:1 support worked really well for my son and I suspect would for a lot of young people.
