value-added

A recent article in Education Week reviewed a study of “value-added” teacher measures. As more discussion takes place about poor achievement in the United States, conversations about how to measure teacher performance and the role it plays in achievement are leading to an increase in the use of value-added modeling. The study’s author, Jesse Rothstein, analyzed three different models and found wide variation that raised questions about the measures. It will be interesting to see where this leads as the national discussion to raise achievement and teacher quality widens.
