It is easy to get stuck in the exploratory and planning phase of UDL. Whether you are implementing UDL as a district-wide mandate, or growing UDL from the ground up one school at a time, making the shift to real-world UDL implementation requires attention to logistics. This conference proceeding discusses the variables affecting the early phases of UDL implementation. It then describes the preparation phase in one school district where UDL was implemented school by school. It covers the selection of schools and school-based leaders, as well as the role of UDL consultants and principals. Additionally, a timeline of preparation tasks is outlined.
