OK then:
DD1 is in Y6. Whenever they do any maths (fgs -numeracy) tests or work that is not teacher marked, the pupils mark their own papers.
One girl on DD's table always manipulates her answers and therefore increases her score by 2 or 3 points each time (usually out of 30).
Now I know that it doesn't really matter as obviously much of their work is teacher assessed and therefore a true reflection of her abilities will be gleaned then. The girl is very bright (although maths is not her strength). I have told DD that the other girl can not be able to feel truly content with herself as she knows she's cheating.
What I'm asking is does it really matter?
My plan was to approach school and suggest that papers are swapped with other pupils on the table (as I remember from my school days), but I am concerned that this would result in a slight raise in the disruption in the class.
Sorry long post but AIBU to report this to school, obviously naming no names?
