We propose in this article that a central element in the large-scale implementation of evidence-based practices is the process by which initial investment in local demonstrations is leveraged into larger implementation efforts. We offer a definition of this "resource leveraging" and propose a process for both measuring and reporting the effects of leveraging. We suggest that resource leveraging become a valid focus of future research and that the intentional measurement, planning, and management of resource leveraging be used to improve the scaling-up of effective practices.
