Just some things in the 5 years I was there (late 80s)... there's been worse since including a child murder that made national news and a very well known child sexual exploitation Court case.
A year 2 (y8) boy ODing on Ectasy at the Christmas disco and ambulance called.
'Hip' Woodwork teacher (very overweight late 30s) openly 'dating' 5th former including sharing a room on a overseas residential.
Same residential, teachers drinking with 4th and 5th years every night. (Y10/11). That trip happened every year and carried on same set up for years later as confirmed by younger siblings. Kids were picked to attend (was meant to be sports based. But not much sport happened!) Boys in girls rooms etc.
Annual 1st years residential where the canoe instructor was a known paedo. Tried it on with several girls each trip (note 11 and 12 year olds!).
For about 4 years there was a Headmaster who no one EVER saw. In fact it wasn't clear if he actually still worked at our school. He seemed to not be there at all but it was always implied he was in his office. No Assemblies nothing. School run by deputy.
Some very sad things. Couple of suicides and just after leaving a boy kills his girlfriend with a pipe.
PE teacher caught shagging history teacher in a store cupboard. Leave their partners. Keep jobs stay at school as a couple.
Geography teacher who obviously drank was renowned for inviting girls to his room for extra support.
School discos with smuggled in alcohol - from 2nd year. Blind eye generally turned. As in no one ever got refused entry or sent home.
A disco where around 8 boys 'slept' with same girl in an empty corridor.
For some reason one of the most notorious stories was a girl telling the deputy head to Go fuck himself when asked to tuck her shirt in. Taking her tie off, throwing it at him and walking off her premises never to return. People spoke of it for years later.
Kid falling off a wall and getting impaled on an iron railing (they survived).
Child going round to science teachers house and throwing a brick through her window. Because she gave a detention.
It was an eventful 5 years. I needed therapy in my 20s just to process it!
