In this paper, the author first presents a Multiple Streams model of policymaking introduced by John Kingdon and elaborated by Robert W. Porter. The relevance and usefulness of the model are then exemplified by analyzing a reform in Argentine education. Kingdon and Porter argued that, for education policies to succeed, the following three streams of actions need to meet: problem must be clearly defined, feasible solutions offered, and political consensus obtained. In 1993, Argentina passed the Federal Law of Education in the attempt to reduce large educational inequities between the rich and the poor. The Law largely failed because (1) problems were narrowly defined only by the government, (2) solutions were one-sided, primarily focusing on the financial, and neglecting contextual and implementation problems, and (3) political will existed only at the highest level, while actual capacities of implementing units were far below those needed for the reform. Analyzing policies through the lens of the Multiple Streams model of policymaking is recommended for other policymakers.
