Im glad Ive seen this thread
My dd13yo, is in a class of idiots.
Her class is the worst behaved in the whole school,the behavior comes from 90% of the boys, and 60% of the girls.
Her class, has had, whole form report for a week, numerous times
Whole class detention, a few times
The best is, last week, the boys in her class were caught having a waterbomb fight in the school corridors, now the whole class is on this behaviour scheme thing, where if every lesson they behave all week, on Fridays they get let out for dinner 15minutes earlier 
My DD has never even had a C1, C2, C3, C4, C5 [these are like bads in your diary, C5 being the least serious, C1 being really bad]
The only ever detention she has had, is because the whole class has received one
In fact her diary is covered in goods [very good work, brill homework etc]
There has been talk of the boys being split up, and transfered to new classes, this talk has been on going for about a year, it is still at the moment just talk
Pisses me right off, my DD always has a good report, is always well behaved, yet her, as well as her similar natured friends in her class are all being punished for the rest of the class"s inability to behave
Its seams, when her class was decided before they started secondary, the school has literally hand picked the naughtiest kids from each primary school, and chucked them all together, barr the exception of a handful of good kids
Everytime, these kids are acting dicks, the teachers attention is solely on that child, while my DD and her friends education is taking a backseat
