With significant state investment, teacher residencies are spreading throughout California. To sustain these efforts after the initial state investment, programs are using creative funding strategies. To learn about how teacher residencies across the state are funding their work, the Learning Policy Institute and "Prepared To Teach" at Bank Street College of Education partnered to examine the current state of practice around residency sustainability. The report highlights California teacher residencies with known financial sustainability efforts in which partners are leveraging local resources to support residents and mentor teachers. This report shares examples from California of partners working together to bring local resources to their residencies to make them more sustainable. The authors begin by setting the California context and briefly describing how finding funding for residencies can help to address teacher shortages while increasing the diversity of the teaching workforce. Then the authors present some concrete strategies that programs can use to move toward long-term sustainable funding for residency programs, with examples of how specific programs in California have successfully implemented select strategies. These strategies could be useful to districts, teacher preparation programs, community leaders, and state policymakers to help inform teacher residency design and supports.
