The article employs district-level administrative and survey data from California and Indiana to examine whether school districts exhibit features of a rational or natural system—in which their behaviors largely reflect fiscal pressures only—or whether they exhibit features of an open system in which nonfinancial factors also shape responses. In Indiana, district fiscal characteristics explain differences in cost-cutting and revenue-raising behaviors; there is little empirical evidence that school districts exhibit features of an open system. In California, both fiscal and environmental attributes, including poverty characteristics, average student achievement levels, and the enrollment of English learner students, explain school district behaviors.
