I combine a national dataset on high-profile education culture wars – dealing with school mascots, curriculum, religion, sexuality, and evolution – with information on student achievement on standardized tests to examine how adult political conflicts impact student learning in the classroom. I show that student achievement declines after an outbreak of controversy, an effect that persists for several years and appears driven mostly by controversies involving evolution and race. In addition to a large-N, “difference in differences” analysis, the chapter provides two detailed case studies, over a controversial school mascot in California and a federal court case involving a Pennsylvania’s district policy to teach intelligent design.
