Good Teachers, Bad Teachers and Data

There was an interesting debate at the New York Times. The question asked was Can a Few Years' Data Reveal  Bad Teachers?

Better teachers lead to better test scores and better lives. But with only a few years' data, can districts tell which teachers are good?
Economists, teachers, and researchers weigh in.


  1. No, because there are too many variables that a teacher cannot control. IE: The homelife of the students. Their willingness to complete their work on time. The attitude of their parents.

    Remember, a manager in the private sector can hire and fire the employees under his supervision. A teacher cannot even choose who is in their class. Big difference.

  2. So not a fan of value-added, huh? Okay. I have to ask, did you actually read the articles?
