It is such a hard thing to decide, but I have decided that
I'm going to push for him to offically repeat pre-prep program with C & K, and start prep one year later. I'm already planning excursions we can do to develop interests instead of over preparing him for prep.
Although his teacher feels he'd be 'OK' and he probably would, he's still young, and has a little social maturing to do. It's not what he knows, it's his school readiness, wanting to try and write, sitting quietly, making friends instead of playing with anyone, the way he paints or draws and the detail or story in them.
The extra 6-12 months at home will do him the world of good, to be able to sit in a classroom for extened periods, to play happily instead of seeking out the silly/clown behavour and being able to articulate more clearly are the biggest things I can see for him. There's also being just that little bit older in year 11 and 12, has to be easier to be 17 instead of 16 in year 12.
I've looked at 2 other boys in similar months (May and June) and personality, their families say the 1st six months was really hard on everyone, they couldn't do any extra stuff after school, such as swimming lessons, and weekends often were just catch up/rest time for the kids. Both at different schools, they tend to be the disruptions in classes. The last term was better, but still the kids struggle, one's going to repeat prep, one might repeat 1st grade if he struggles with it next year.
I feel if your child's going to be one of the younger ones compare your child to the 5y.olds, are they similar in social aspects? -knowlege comes at school, but if they're not able to sit, they can't learn.
My school is luckily quiet helpful, but would rather see him repeat prep if needed, which I think is worse for my son (he doesn't move on from friendships well, too long a memory).
I think Mum's are the best judges, talk to as many people as you can, but if you're in doubt, keep him at home, you are the best expert on your son. Good luck with your boys.
