This document summarizes a presentation about the strategic implementation of Universal Design for Learning (UDL) in schools. It discusses how initial UDL projects are difficult to scale up institution-wide and require developing new leadership skills. The presenter examines challenges encountered, such as lack of planning, confusion over leadership, and resistance to change. They propose using an ecological model to analyze barriers within an institution's environment before implementing UDL school-wide. This would help tailor the approach to each context and avoid false starts. The presenter argues more research is needed on the strategic, institutional development of UDL.
