Conflating the importance of teacher quality with the ability to measure it carries big risks, and can lead states, districts and the media to miss the trees for the forest.

A teacher writing about plans by the NYC Department of Education to release teachers’ names and value-added ratings to the press, says: "Is this sheer stubbornness on the part of school leaders, or do they not understand the harm this would cause?"

Ravitch: Why teachers should never be rated by test scores

Education historian Diane Ravitch writes: "...Value-added assessment should not be used at all. Never. It has a wide margin of error. It is unstable. A teacher who is highly effective one year may get a different rating the next year depending on which students are assigned to his or her class. Ratings may differ if the tests differ. To the extent it is used, it will narrow the curriculum and promote teaching to tests. Teachers will be mislabeled and stigmatized. Many factors that influence student scores will not be counted at all."

Willingham: Big questions about the LA Times teachers project

Cognitive scientist Daniel Willingham explains why using value-added measures to judge the effectiveness of a teacher is a mistake, and says that the Los Angeles Times writers who helped evaluate more than 6,000 teachers in this fashion, "are either uniformed or disingenuous about the status of the value-added measures."
