Pickled, I don't think any of those things are right. We sent dd to a local state school, outstanding, with excellent results and excellent reputation. There had been a new head and all of a suddent standards went out of the window. There was constant disruption, swearing at staff, bullying, thieving, violence, etc, etc.. The head claimed there was nothing to be done and the school was a comprehensive with a diverse intake. The previous head had managed to deal with it very successfully. The original, dedicated, committed staff started to peel off. Our dd peeled off at the end of Y8.
Luckily we had the means to send her independent. I can honestly say my eyes were opened. It was horrific and I don't mind being battered on here by teachers for saying it, it did nothing to impress upon me the professionalism of the teaching profession overall. Individually some of the staff were fantastic, the governors, however, imo were a bunch of professional committee sitters and joining them would have been a waste of time.
The girls at the indy are not all little angels but if they misbehave there are consequences. Since September there has been a one day suspension and for another girl a three day suspension. The latter girl and her family are in no doubt she is on her last chance and if she puts one more foot wrong it will farewell and not a fond one.
I am sorry you have been so lambasted on here. If teachers thought those things were wrong they would not happen and the majority would be able to learn and to fulfil their potential.
