It may sound impolite for me to say that it is NOT new. In Chapter 1 of Freakonomics, titled "what do school teachers and sumo wrestlers have in common", the authors explain the phenomena clearly.
It is no use to trying the catch the cheater. It is the system and to solve the problem, we should fix the system.
What if when a school is found under-performing, a huge amount of resources are poured in to help. Then every school, in chasing the resources, will push up its standard to look under-performing!
Got it?
