Paul Sabatier and Hank Jenkins Smith introduced the Advocacy Coalition Framework (ACF) in the late 1980s, to refine the theoretical and methodological tools available for the study of the policy process. In the past two decades, the framework has grown in use outside the United States, and it is now applied to study a broad range of policy arenas in all continents. ACF scholars have created a core community that regularly synthetizes findings from applications of the framework, giving the ACF the form of a true research program.
The ACF has three principal theoretical domains: advocacy coalitions, policy subsystems, and policy change. Expectations about the interactions between and within these domains are contained in 15 main hypotheses. The ACF posits that advocacy coalitions and policy subsystems are the most efficient way to organize actors interested in the policy process for empirical research. The policy subsystem is the main unit of analysis in the ACF, and there are four paths leading to policy change. The aspect that has received more attention in existing applications is the effect that external events have on policy change, and some areas in need of refinement include: policy-oriented learning, interactions across subsystems, the theoretical foundations to identification of belief systems, and how the interactions between beliefs and interests affect coalition behavior.
