This is not a stealth boast - but a genuine question.
I won't give all the background (there is some) but just keep it short.
If a child got 118 in SATs for both English Reading and SPAG would you expect the school report mark to be "Standards related to their age"? Or would they be at "Working at Greater Depth"?
I know there is more to everything than SATs - but all the mocks the child has done have been completed at a similar high level - so not just a one off fluke.
