I was a prefect at primary school but at secondary school my behaviour took a downturn! In my third year I held the record for detentions, though being at a girl's grammar school it wasn't actually many. I wasn't a goody goody even at primary school, being described in one school report as a 'Likeable rogue'! I was naughty but not nasty!
Some of my detentions were very unfairly given as my form tutor was a neighbour, to whom my mother, a teacher at another school, said "If she misbehaves don't hold back. We won't be round to complain if she is punished!" As a result I was given detentions for trivial things and often took the blame for things others were also involved in but got away with! My mother would never accept that I was not the only one at fault when I was the only one punished. Sadly the teacher in question could not control his classes even in the environment that existed in the 1960s. He certainly wouldn't have survived in todays schools, or even a more challenging one back then!
To be honest I feel sorry for the guy. He can't have been very happy in his work. By the time I was a sixth former the school had stopped selecting prefects, and all sixth formers had prefect priviledges, being able to give discipline to younger pupils in the form of order marks, 3 of these resulted in a detention. None of the schools I've worked in had a prefect system, though most had 'Head girls and Head boys'. At my children's school there was a system of awarding a 'Senior Pupil Tie' to the well behaved among year 11s. My DD got one but DS didn't. I think his behaviour genes came from me while DD got more from her dad who was a school swot!
