Winsor Learning, Inc. is an educational publishing and consulting company based in Bloomington, Minnesota, founded in 1997. Its work centers on improving reading outcomes in K–12 settings, drawing on scientifically grounded approaches to reading instruction. The organization has provided intervention and professional development to thousands of school districts, focusing on timely identification and support for students who are falling behind in reading. The Sonday System, developed with Orton-Gillingham expert Arlene Sonday, combines established multisensory instruction with enhanced usability to enable educators and volunteers to identify, intervene, and help struggling students catch up with their peers. In addition to its core instructional tools, Winsor Learning has expanded into professional development offerings and related resources to support literacy instruction across grade levels. The company sits within the primary and secondary education sector and operates as a supplier of both intervention materials and consulting services. A notable development in its recent history is the acquisition of Winsor Learning by Imagine Learning, announced in 2023.
