Ok a few answers to questions.
If you don’t have the knowledge to teach, then you facilitate, encourage and motivate using the wealth of resources that are available. This might be text books, online courses or resources, other adults or tutors. There are home ed groups, clubs. Forest school etc. Some are paid for and some are free.
Most adults could figure it out. You join some groups and read up on your rights and responsibilities. Many who home educate do so out of necessity. Almost all parents want the absolute best for their children.
You don’t get fined and can take holidays in term time. It’s a bonus!
Home ed kids can sit exams (although there is a cost involved) and then go on to college and university same as anyone else. They just need to meet the entry requirements for the course.
You don’t need a ‘routine’ unless you decide that’s what works for your child.
I don’t know anyone who thought/thinks home ed is the easy option.
PE or rather sport and exercise do not have to be done in school. If team sport isn’t your thing though you don’t have to endure being last to be picked!
I don’t believe school prepares us for the real world. It’s the most artificial social structure there is. When else are 30+ people of the same age but often little shared interest in the activity on offer lumped together?
Teachers need special skills because they are required to teach 30+ kids at once! That is a very particular skill set. Teaching 1:1 is a very different thing.
There is no requirement to sit as many GCSEs as they do in school or indeed any.
it is possible to work full time and home ed. In particular older kids or where grandparents are involved or parents can tag team. Also home ed can fit around work. There is no need to do as many hours as they would in school. No need for mon-fri 9-3 either. No need for 6 weeks off in the summer either. It’s very flexible.
There is no requirement to follow the national curriculum.
Most GCSEs can be studied for in a year. It all depends on what the rest of your workload is like.
I am a single mum and work full time. I home educated my son through his GCSEs using online courses and resources. He also did art, and we covered PHSE and life skills. He got the grades he needed, went on to college and is now at uni. It was the best thing we could have done and I am super proud of how far he has come.
