I didn't read @Mrsbabbecho as saying all state school parents are awful and I'd be surprised if that's what she meant.
But I'll be honest, one of the reasons we are hoping to switch from state to indy in the next few years is because of the relatively small number of disruptive children at state secondaries near us who frankly ruin it for everyone else.
Whether they are 'badly parented', have unmet SEN or both, it means teachers spend too much time zookeeping and not enough time teaching. And even without outright disruptive behaviour, there is a minority of kids whose families don't place much value on education, and whose kids see no point in working hard or aspiring to do their academic best. And I don't want my children to be around them.
No doubt you will tell me how you know lots of independent schools are full of highly disruptive children and that little [insert posh sounding name] burned down your local private school, while state schools are universally filled with dedicated impeccably-behaved children all from high-aspiring and supportive families.
All I can say is that I've done my research and it's not like that round here (and indeed judging by a number of threads I've read on MN from state school teachers outlining just how bad things are on the front line, that's not the case in many other places too).
I wish it were otherwise, but it's not.
And Labour screwing the private sector to raise enough (in a best reasonable case scenario) to pay for a third of an extra teacher per state school isn't going to make the blindest bit of difference.
