Tennessee teachers have filed a second lawsuit this year challenging the state’s use of student standardized test scores to determine teachers' retention and merit pay evaluations. Governor Bill Haslam and Commissioner of Education Kevin Huffman are named as defendants in the suit filed by Knox County teacher Mark Taylor, an eighth grade science teacher who said that he was unfairly denied a bonus after his teacher effectiveness score was based on the standardized test scores of only 22 of his 142 students. In 1992, Tennessee’s General Assembly passed the Education Improvement Act to establish “a statistical system for educational outcome assessment that uses measures of student learning to enable the estimation of teacher, school and school district statistical distributions,” called the Tennessee Value Added Assessment System (TVAAS). TVAAS estimates measure the impact that teachers, schools and school districts have on the educational progress of students based on state standardized tests results in grades 3 through 8. Because Tennessee sought Race to the Top federal funds that require local districts to measure teacher effectiveness on student standardized test scores, the TVAAS is heavily weighted in teachers’ overall effectiveness score for hiring, retention, and incentive decisions.
For the plaintiff Taylor, who teaches four upper-level physical science courses and one regular eighth grade science class, only the standardized scores of his general science class counted in his TVAAS estimate. The student scores in his higher-performing upper-level classes, measured by local tests, were not included in his evaluation. Taylor was denied a bonus under the teacher evaluation program even though he says the observation component of his evaluation showed that he was exceeding expectations. Taylor argues that the state violated his 14th Amendment right to equal protection from “irrational state-imposed classifications” by using a small fraction of his students to determine his overall effectiveness. Last month, Knox County teacher Lisa Trout challenged the TVAAS evaluation system after she was denied a bonus. Trout alleged that she was misled about how her TVAAS estimate would be calculated. The Tennessee case is Taylor v. Haslam, No. 3:14CV00113, 2014 WL 1087776 (E.D.Tenn., filed March 19, 2014). Read more at the Tennessee Education Association here.
