You’ve arrived at your destination! Full implementation or expansion occurs when new practices have been successfully integrated into all aspects of programming (e.g., practitioner; organizational; policies; procedures; etc.) with at least 50% of practitioners implementing practices with fidelity and good outcomes. Districts are ready to consider expanding towards full implementation when pilot classrooms have the needed resources and supports to sustain the new initiative with fidelity. The focus of assessment and planning then becomes identifying additional sites, new staff cohorts, and additional training needs. The district team needs to add representatives from its new sites and will proceed through each of the four implementation stages to assess and plan fidelity of practices at the new sites. As with initial implementation, full implementation often involves creating individual site building teams that monitor their practice fidelity.
