Teachers' Union Sues Gov. Haslam in Test Scores Case

Teachers' union files 2nd test scores lawsuit

NASHVILLE, Tenn. (AP/WMOT) — Tennessee's largest teachers' union is suing Gov. Bill Haslam and State Education Commissioner Kevin Huffman.

They’re named in the latest Tennessee Education Association lawsuit, which also includes the Knox County Board of Education as a defendant.

It's the second lawsuit this month the agency has filed against the Knox County board. Both claim student test scores used to assess two teachers' performances were flawed and cost them bonuses.

TEA President Gera Summerford insists the Tennessee Value-Added Assessment System shouldn't be relied upon because it's a statistical estimate.

“What we find is that there’s a large standard error in those TVAAS estimates. So they are not precise. They are much more volatile than we originally thought.”

Summerford says the governor and commissioner were included in the lawsuit because, as she worded it, "this really is a state issue."
