Evaluating public policies: a theoretical review of a field under construction

Abstract

This article performs a theoretical recovery of the literature about public policy in general, and evaluation of public policy specifically. The theoretical and historical understanding of a given field of knowledge is essential for its practice, including a better understanding of its consequences, its trajectory, and perspectives. The article begins with a general overview about public policy, its origins, and conceptual dimensions. It then continues with a discussion about this theme in Brazil, taking into consideration mainly the more recent years. The evaluation of public policy is observed more deeply for it has received numerous definitions within the literature. Three main phases of evaluation are identified since the 1960s until the present date. Subsequently the article presents some methodologies concerning the evaluation of public policy, including its several classifications, timing, the evaluator¿s position, criteria and structure. Finally, it comments on the possibility of the application of meta-evaluations, as well as on the emergence of new issues that impose themselves into the participative-democratic Brazilian context.
