When DC's level in Y2 is assessed I've noticed they look for indications the criteria have been met for moving for from a level 2C to a 2B for example.
Question is what if a 2C in reading is actually a level 3 for example, can ability that exceeds the criteria for the next jump ever be missed?
If you are being assessed for the next 'stage' can a surge in ability be ever overlooked?
