Master teacher Sheri Lederman is suing the State of New York after having received a low rating on the state’s “growth” measure. Her husband Bruce is her lawyer. She has been teaching for 18 years and has earned her doctorate. While only 31% of the students in the state “passed” the Common Core tests as proficient, 66% of the students in Dr. Lederman’s class were proficient. But the state gave her a low rating because, by the state’s convoluted formula, the students did not “grow” enough in their test scores.

The New York State Education Department tried to get the lawsuit dismissed, but their effort was rejected and the case is moving forward.

One of the strengths of the Lederman’s case is the excellent affidavits submitted by experts, as well as by parents and students. You can read the affidavits here. You will be informed by the expert statements of Linda Darling-Hammond, Audrey Amrein-Beardsley, Carol Burris, Aaron Pallas, and Brad Lindell.

Darling-Hammond says that Lederman’s rating is “utterly irrational.”

Amrein-Beardsley says that no VAM rating–given the current state of knowledge or lack thereof– is sufficient valid or fair to rate individual teachers.

You will find the testimony of parents and former students enlightening.
