The politicians won’t rest until they can fire more teachers. John King is their man. He has the system that mo one undestands but that is guaranteed to find some teachers to fire.

The politicians know that if they fire a bunch of teachers, it will surely lead to higher achievement and will close the achievement gap. The fact that it has never happened anywhere doesn’t faze them. What has evidence got to do with it? The important thing is to fire enough teachers to satisfy the politicians.

I have said it before and I will say it again: evaluating teachers by test scores is junk science.

When Sidwell Friends and Fieldston and Exeter do it, then we will know it has merit. Until then, it is politically motivated nonsense.
