Proponents of market-based education reform often argue that introducing charter schools and other school choice policies creates a competitive dynamic that will prompt low-performing districts to improve their practice. Rather than simply providing an alternative to neighborhood public schools for a handful of students, the theory says, school choice programs actually benefit students remaining in their neighborhood schools, too. Competition motivates districts to respond to the loss of students and the revenues students bring, producing a rising tide that, as the common metaphor suggests, lifts all boats. In order for this to happen, districts must first recognize the need to compete for students and then make efforts to attract those students, who now have the chance to go elsewhere. Since 2007, enrollment in charter schools has jumped from 1.3 million to 2 million students, an increase of 59 percent. The school choice movement is gaining momentum, but are districts responding to the competition? In this study, the authors investigate whether district officials in a position to influence policy and practice have begun to respond to competitive pressure from school choice in new ways. Specifically, they probe whether district officials in urban settings across the country believe they need to compete for students. If they do, what is the nature of their response?
