With all the pressure on our flawed educational system to get good results has led some teachers to cheat on student test scores.
Are we surprised?
I had a few really good teachers during my slave days in the government school system, but I also had quite a few who were barely making it. This is what will happen whenever the government takes over something. The mediocre rise to the top, since you cannot reward excellence and still have everyone do well and feel good.
The system encourages cheating, however much we may act in pretend shock when it happens.
