At my school the report books yes there were ‘books’ so the reports were filed sequentially, and contained a list of various statistical information including times late, days absent, detentions and , yes, school canings. They were in a row of boxes on the top line. They were supposed to vbe filled in by the deputy head, who also had a comments box for remarks on overall academic progress and discipline.
I’m afraid I put Miss F in a difficult position over this. When I was first caned she had asked me routinely if I was ok, or words to that effect. My response was tangential, asking if ( because I really didn’t know) the school intended to write home. She replied of course not, ‘what happens in school stays in school, and added, as she knew my mother well, that unless directly asked she would never raise the issue. Given my mother’s attitude to corporal punishment, there may have been an element of self-preservation here!
