Here's the statement from the Ohio Education Association, which represents over 121,000 educators

Responding to a series of newspaper, web and radio stories on value-added scroes of individual Ohio teachers, Patricia Frost-Brooks, President of the Ohio Education Association criticized the fairness of the stories and the wisdom of using value-added scores as such a prominent index of teacher success:

"The Ohio Education Association was not contacted for comment on the Plain Dealer/StateImpact Ohio stories, despite our expertise, which would have provided desperately needed context and perspective. Reporters and editors admitted this value-added data was 'flawed,' but they chose surprise and impact over fairness, balance and accuracy," Frost-Brooks said.

"We are all accountable for student success – teachers, support professionals, parents, students and elected officials. And the Ohio Education Association is committed to fair teacher evaluation systems that include student performance, among other multiple measures. But listing teachers as effective or ineffective based on narrow tests not designed to be used for this purpose is a disservice to everyone.

"Value-added ratings can never paint a complete or objective picture of an individual teacher’s work or performance. Trained educators can use a student’s value-added data, along with other student data, to improve student instruction. But the stories promote a simplistic and inaccurate view of value-added as a valid basis for high-stakes decisions on schools, teachers and students."

Very questionable that reporters would not contact the largest teachers assoication in crafting their story.
