I remember reading a form which the education authority had sent out to schools which, when suggesting boundries for c.p.in school commented, ‘boys are to be caned no more than six strokes, girls and younger boys are to be punished as a reasonable and caring parent would.’ I assume this would mean bottom smacking or bottom slippering, as this was the usual punishment administered by parents.
I think this would mean teachers could get away with spanking girls bums of all school ages, and all c.p. was to be administed by the headmaster only.
