We sent Ds to an all boys state secondary but I far preferred the local mixed comp as did ds. We were a bit strong armed by family to ignore our instincts and I now sometimes regret it as I realise the school he is at is so old fashioned and doesn't see the children as individuals just as results.
Even if I were to be able to move him I would fear the damage of upheaval. He is not even very unhappy, he just seems to me to not be thriving and I think the other place would have suited him much better. He's not super academic either.
Any way, I just wondered if anyone had any experience of this.
