Conversations around changes to music teacher evaluation have publicly played out for the last decade. These discussions largely have focused on discrete aspects of the new accountability systems, including the particulars of observations, measuring student growth in non-tested grades and subjects, the motivation for changes to teacher evaluation, and myriad potential problems and unintended consequences involved. However, the underlying logic that drives these changes has been relatively ignored. I suggest that lurking beneath the surface of recent accountability systems is "performativity", an approach to education that reorients schooling toward the competitive needs of the economy. In this "production" model, teachers are narrowly defined as effective if they produce specified results in the form of standardized test scores or successful completion of student learning objectives. This article offers vignettes of music teachers' struggles under performativity to illustrate the dilemmas faced by conscientious educators, and it addresses some of their concerns.
