Surprise: Most of the teachers in Ohio are effective or highly effective.

 

However, there are more ineffective teachers in districts with high levels of poverty.

 

Chicken-and-egg? Correlation?

 

Lesson: if you want to be a highly-rated teacher, avoid high-poverty schools and districts.

 

Second lesson: This is a ridiculous way to evaluate teachers, and the results were predictable and flawed. Also meaningless.

 

How many millions were spent to learn this?
