This brief from Prepared to Teach describes positive findings from several new residency models created in partnership with St. Cloud University. Highlighting best practices and results from these partnerships, the brief depicts factors that were found to be helpful in designing their co-teaching residencies, offering lessons that may prove beneficial for programs beginning to explore similar pre-service instructional models. The brief includes lessons from programs focused on classroom teachers, ideas on co-planning in the context of already busy school days, and approaches for building a common co-teaching language and vision. The combined resources, ideas, and activities will be particularly helpful for educator preparation program administrators and pre-service co-teachers.
