Much of the discussion about the use of student standardized test scores to evaluate teachers has centered on how unfair the “value-added” method is to teachers because it is unreliable and can — and does — label effective teachers as ineffective too often. But there are consequences for the students too, and they are just starting to be seen. This is explained by in this post by Carol Burris, the award-winning principal of South Side High School in Rockville Centre, New York. She is the co-author of the New York Principals letter of concern regarding the evaluation of teachers by student test scores, which has been signed by more than 1,500 New York principals and more than 5,400 teachers, parents, professors, administrators and citizens.
