Supporting individuals with developmental disabilities such as autism, as well as their caregivers and service providers, is central to the work of FPG. Understanding developmental trajectories and the impact of a developmental disability on the individual, family, and broader community informs both theory and practice. High-quality intervention across the age range can ensure that individuals with developmental disabilities and their families fully participate in their community in ways that are meaningful to them. FPG investigators have identified central features of high-quality intervention, such as family-focused programming, early childhood inclusion, and the use of identified evidence-based practices. They lead the field in translating scientific knowledge into practical information for teachers and service providers, and actively join their colleagues from implementation science in promoting adoption and use of effective intervention practices in schools, homes, and community settings.
