Business-inspired school reform policies in the United States date back to the late 19th century. In the last four decades, however, while school reformers have continued to borrow policies and practices from the business world, the dominant business model itself has changed dramatically as part of the financialization of the economy. Once a bureaucratically governed social institution, focused on long-term stability and committed to multiple stakeholders, the corporation has become a destabilized network of temporary contracting relationships, singularly focused on maximizing shareholder value. This conceptual article explores what it means for schools, as public and democratic institutions, to emulate business in the era of financialization. Through analysis of several recent trends in business-inspired school reform policy, I demonstrate the diffusion of financialization logic and practices into public schools. I argue that while business may have "historically" been a problematic model for educational policy, business is now a uniquely unqualified model.
