DC are Y10, Y8 and Y6.
The eldest two are at the local comprehensive. It's fine. Leadership is good. Low staff turnover. Decent results. Behaviour OK. Walkable and in a nice area. DC3 due to start there next September. All the DC are reasonably academically able - definitely not prodigies but generally do well, although I don't think they are meeting their potential (which I don't blame the school for, but realistically I would like to see them being challenged just a bit harder).
We would have liked to be able to choose independent secondary for them all, but we ran the sums years ago when DC1 was in late primary, and with three children it was just not realistic. However, our circumstances have recently changed (due to bereavement, sadly), and we are now in a position where we could theoretically switch to the independent sector. There are a number of great local indies.
But. DC1 is in Y10 so a move is out of the question, really. DC2 could in theory move for Y9 but she is settled with a great group of friends (some from primary and some new additions) and I don't think would want to move. We certainly wouldn't make her, and I've not idea if we could have her ready for the common entrance exam anyway or if there would be places available.
Moving either or both of then for sixth form would probably not be worth the expense - there is an academically very strong sixth form college locally which I think will suit them - they are both interested in the 'core' subjects and wouldn't particularly be swayed by the broader options available at the independents.
So - DC3. He's a quirky little chap and of the three of them, I feel he is the one that would benefit the most from smaller class sizes and a calmer learning environment. But we feel very conflicted about the idea of choosing such a different path for him, and one that we couldn't offer the other two when it would have been an option.
We have thought about the option of giving DC1 and 2 extra help with house deposits etc in the future to 'even things out' but I'm not sure that really solves the problem. DC3 is clearly way too young to make a decision about what he would prefer, and who knows, perhaps he might end up feeling he would have valued help as a young adult over a private education.
I'd be really interested in hearing from anyone who has faced a similar situation. I've looked at other threads, but most either seem to be parents who have chosen different schools for different children for reasons other than cost, or who have a children in a mix of indie and grammar and are equally happy with both. For us, the reality is that DC3 would in all likelihood be getting a better education than his older siblings.
