What does it take to scale up and sustain evidence-based practices?

This article discusses the strategic scaling up of evidence-based practices. The authors draw from the scholarly work of fellow special education researchers and from the field of learning sciences. The article defines scaling up as the process by which researchers or educators initially implement interventions on a small scale, validate them, and then implement them more widely in real-world conditions. Examples of scale-up research are included. The authors discuss challenges to scaling up and sustaining evidence-based practices, followed by factors that can potentially support scaling up, including professional development and district leadership. A case example describes how these issues can play out by highlighting experiences with a Collaborative Strategic Reading (CSR) scale-up research project in a large urban school district. The article concludes by offering recommendations for research, policy, and practice.
