Another theme cuts across the chapters in this section: Organizations are principal mechanisms for implementing educational policy. Spillane, Gomez, and Mesler’s chapter explicitly addresses this subject. Other chapters assess policies that focus on organizational units, ranging from classrooms to schools to school districts. To improve education, we reduce the size of classes and schools (Ahn & Brewer); reconstitute schools (Malen & Rice); seek to equalize inputs and outcomes across schools (Baker & Green) and effectively allocate resources in schools (Plecki & Castañeda); expose schools and districts to market pressures (Belfi eld & Levin; Hess) with charter schools (Vergari) and vouchers (Witte). The reliance on educational organizations as policy mechanisms refl ects dominant social and cultural norms. As Zucker (1983) reminds us, organizations are “the preeminent institutional form in modern society” (p. 1). What we do as a society, we largely accomplish though organizations.
