In San Francisco, where both housing costs and income inequality continue to grow, the San Francisco Unified School District (SFUSD) is increasingly focused on supporting homeless children and families. To inform this work, SFUSD partnered with Stanford University's Graduate School of Education (GSE) and John W. Gardner Center for Youth and Their Communities (Gardner Center) to conduct research aimed at helping SFUSD better track, understand, and support their homeless and highly mobile (HHM) student population. The researchers aimed to further advance understanding of the student assets that promote resilient adaptation and educational success of HHM students. Specifically, they examined how HHM students' social and emotional learning (SEL) skills--including self-management, growth mindset, self-efficacy, and social awareness--may support their academic achievement by addressing the following research questions: 1) What is the size and distribution of HHM students in SFUSD across different grades, schools, racial ethnicities, and language backgrounds? 2) How heterogeneous is this student population in terms of chronicity of HHM status, instability of living arrangement, placement in foster care, and number of siblings? 3) What promotes resilience and positive outcomes for HHM students?
