I think that clip boards must have been a local idea..I do not recall passing it to someone else to mark..But when I was a kid, the reviews were monthly. The School Overseer collected all the papers back in and marked them (at least for School Members) and returned it next week with his cryptic comments.
The School was run much more like a real school in those days. Each week it would open with a register being called and you had to call out "present " when your name was called, or there was deafening silence if you were absent or late. The counsel was pretty "direct " as well. It was no place for the fainthearted or easily offended.
The School Servant that we had in those days left and became one of the "evil slave" - He told me much later that he disliked the business methods they used, perhaps that was something to do with it.
