...the top sets?
I work in a school, and time and time again I see this anomaly and wonder how such things are decided? Surely the HOD / Assistant Heads, Deputy heads and experienced teachers should be teaching the more challenging pupils because teaching is what they are good at (otherwise they wouldn't have been promoted). Also they are paid more, in my mind it should be for doing some of the more difficult teaching jobs.
I know that the top sets arn't full of angels and low ability sets arn't all little sods but nevertheless the top sets are easier to teach because of their ability and behaviour in general. It would make sense therefore for the newer / less able teachers to teach these sets. In the same way I am sure inexperienced surgeons start with the easier ops while the experienced ones do the more challenging ones (perhaps I got that wrong too?).
