As more and more schools adopt school-wide positive behavior support (SWPBS) as a model for school improvement and the success of initial demonstration sites becomes evident, districts are faced with expansion and sustainability issues. Careful planning of these implementation efforts requires district personnel to be familiar with the resources and supports needed to implement and sustain such district-wide systems change efforts and build an infrastructure to support SWPBS initiatives. The purpose of this article is to expand upon "School-wide Positive Behavior Support: Implementers' Blueprint and Self-Assessment" (Sugai et al., 2005) by describing the how-to of the SWPBS implementation process with specific activities and providing user-friendly tools that can assist a district in "going to scale." Obstacles to and future considerations for expanding the practice of SWPBS are also presented. (Contains 4 figures, 1 table and 3 notes.)
