In recent years, the federal government has invested billions of dollars to reform chronically low-performing schools. To fulfill their federal Race to the Top grant agreement, Tennessee implemented three turnaround strategies that adhered to the federal restart and transformation models: (a) placed schools under the auspices of the Achievement School District (ASD), which directly managed them; (b) placed schools under the ASD, which arranged for management by a charter management organization; and (c) placed schools under the management of a district Innovation Zone (iZone) with additional resources and autonomy. We examine the effects of each strategy and find that iZone schools, which were separately managed by three districts, substantially improved student achievement. In schools under the auspices of the ASD, student achievement did not improve or worsen. This suggests that it is possible to improve schools without removing them from the governance of a school district.
