Hi @gentileschi
Sorry you are going through this. It must be very difficult and stressful.
Im an ex primary teacher and now home educator of several years and I can answer some of your HE questions.
No there is no body that oversees HE. Your local authority send an annual report for you to fill in and that’s generally it (some LAs are more relaxed than others, some require more detail in the reports etc).
If you join the HEFA Facebook group (Home Education For All) the admins will help you write reports and give you advice on dealing with your school and the LAs. They are very knowledgeable and helpful.
If you do decide to HE, and it sounds like your son would really benefit from a child-led learning environment, you could join your local HE Facebook group to see what is going on in your local area. You’ll normally find things like forest schools, sports groups, social events etc.
Last bit of advice, give your son some time to ‘deschool’. He’s only 5 so it shouldn’t take too long. Let him play, let him lead the way. My DC are teen and tweens now and I have never regretted letting them follow their interests or worried about them ‘keeping up’. It’s very hard for some people to understand but kids just learn spontaneously without a desk and a teacher. Mine learn through real life. They learn geography from traveling, they learn maths when baking, when making things with wood, they learn to read themselves (this one blows peoples minds!) and on and on. They love learning as they learn what interests them. It’s hard to explain in a short post but it’s true.
Socially they are very ‘normal’ and have many opportunities to make friends and to meet a huge variety of different people of different ages and different cultures and backgrounds. In my humble opinion school is generally not a healthy way for people to socialise. Being with exact same age children all day every day is not healthy or normal in my opinion.
I hope this helps. Happy to answer any other questions you have.
