Resource leveraging is the process by which the outcomes from initial investment in personnel, materials, and events to achieve a targeted goal result in additional investment toward that goal. The assumption governing this concept is that without an initial, small investment, larger future investments are less likely (Rogers, 2003). Our thesis is that large-scale implementation of evidence-based educational practices often requires that initial implementation investments be used to leverage the size, scope, and sustained investment needed for scaling to occur. The purposes of this article are to offer a more operational definition of "resource leveraging," encourage the measurement of leveraging, and propose that leveraging be considered not just a topic of conceptual interest, but a formal tactic for any long-range implementation plan. We believe that the intentional measurement, planning, and management of resource leveraging will improve our ability to scale up effective practices. It is appropriate to consider the role that resource leveraging plays in education given the current emphasis on adopting evidence-based practices (
