About your dyslexia: you don't have to teach your son yourself. When you home educate, your role is to help him find resources so he can learn things. Besides, you probably DO know quite a lot that you can help him with.
Through home education, my older child made a good friend when they were 12. The mum had such severe dyslexia that I often couldn't understand anything she was trying to express in her messages. She also had unclear and disorganised speech as a result of a head injury and having been deaf as a child. So it was also difficult for me to understand her when I spoke to her. She was a lovely person.
I'm an academic high achiever with several degrees who won national spelling competitions as a child and writing scholarships in my teens. I've worked as a university teaching assistant and a maths tutor.
Most people who know nothing about home education would predict that of those two, my child would get the better education, would learn to write better and speak better and get better academic results.
As it turned out, those two kids ended up with very very similar outcomes. When I first met this 12 year old, she was reading a novel which was over 1000 pages long. I helped her with her CV when she was 16. Her draft was perfectly competent, with the presentation you would expect of the average 16 year old. Her speech was clear and well organised. She was a natural at marketing and sales. Exactly like my child, she delayed taking her GCSEs until later in her teens, put in relatively little work 😂and got decent results, 5s to 7s if I remember right.
Why? Home educated kids aren't shut up in a box with only their parents to teach them. They have access to the whole world. They just need a parent who loves them enough to encourage them and to help them find out what they want to know. What's more, this young girl may not have learned how to spell from her mum, but she did learn many valuable things from her. She learned to be a go-getter, to ask for what she wanted, to care about other people and be involved in the community, to work hard, to come up with creative solutions. She's a happy and successful 25 year old now.
