This is a second panel submitted to the 2014 conference about policy and program implementation. It’s structure highlights a finding from a recent systematic review of the last 10 years of published literature that approaches to implementation studies are quite divergent and that new, integrative models are necessary. Considerable expansion has happened in investigations of particular interventions programs, in what is called “implementation science” that is particularly focused in the health and education, as well as in research that considers how such evidence-based interventions are replicated and scaled. Yet, research in political science and public affairs has slowed, largely because of failed attempts to specify predictive models concerned with implementation success. This panel brings together researchers from across these communities to consider new methods and models. While each contributor will offer a solid paper, there will also be unique opportunities in the session to talk about what is similar and differences in these distinct approaches to implementation studies. In this way, the discussion itself will promote new opportunities for integration.
