Respected Teacher Sues State Over ‘Ineffective’ Evaluation Label

Lederman

Reposted from the Washington Post:

Sheri G. Lederman has been teaching for 17 years as a fourth-grade teacher  in New York’s Great Neck Public School district. Her students consistently  outperform state averages on math and English standardized tests, and  Thomas Dolan, the superintendent of Great Neck schools, signed an affidavit saying “her record is flawless” and that “she is highly regarded as an educator.” Yet somehow, when Lederman received her 2013-14 evaluation, which is based in part on student standardized test scores, she was rated as “ineffective.” Now she has sued state officials over the method they used to make this determination in an action that could affect New York’s controversial teacher evaluation system.

The evaluation method, known as value-added modeling, or VAM, purports to be able to predict through a complicated computer model how students with similar characteristics are supposed to perform on the exams — and how much growth they are supposed to show over time — and then rate teachers on how much their students compare to the theoretical students. New York is just one of the many states where VAM is one of the chief components used to evaluate teachers.

The lawsuit shows that Lederman’s students traditionally perform much higher on math and English Language Arts standardized tests than average fourth-grade classes in the state. In 2012-13, 68.75 percent of her students met or exceeded state standards in both English and math. She was labeled “effective” that year. In 2013-14, her students’ test results were very similar but she was rated “ineffective.”
