Thinking about it, I avoided high school, but I did it by truancy. My niece didn’t go to school after year 7 either, but people are more on it now. She’s autistic, and to be perfectly honest, I suspect I am too, in a less severe sense.
I would register, then leave school and walk on the beach, in all weathers, just to avoid being there, and to be in nature. My niece rarely leaves her bedroom (she’s 19 now).
I wonder, if there were smaller groups which learnt mostly outdoors, and avoided technology, whether some children could stay in education longer. I supported a child in KS1, again with autism and adhd, who I mostly taught outdoors. He thrived in that setting, but found the classroom overwhelming. He also found Forest School a struggle when the whole class were there, but we spent a lot of time in the forest by ourselves (it was adjacent to the playground).
I recognise that this wouldn’t solve all school avoidance, but I’d like to bet that it would help at least 50% of children who struggle currently.
Tech is too easy an escape, I think, and some children (and adults) become reliant on it to the point where it’s really unhealthy.
