For the past year, the San Francisco Department of Children, Youth, and their Families (DCYF), San Francisco Unified School District (SFUSD), and the John W. Gardner Center for Youth and Their Communities at Stanford University (Gardner Center) have collaborated to examine SFUSD student participation in DCYF-funded programs. This analysis utilizes the Youth Data Archive, a Gardner Center initiative that links administrative data on individual youth across settings to collectively examine questions that agencies could not answer alone. The partnership will help DCYF understand which students its programs serve and better match its programs to students who need the most help. The following research questions guided the findings presented in this report: (1) To what extent do SFUSD students participate in DCYF programs? (2) What types of SFUSD students are more likely to participate in DCYF programs? (3) What are the longitudinal patterns of participation in DCYF programs? (4) To what extent do high school graduates and postsecondary students from SFUSD participate in DCYF programs? The research finds: (1) DCYF serves a significant share of the SFUSD student population; (2) Participation in DCYF funded programs steadily increased over time; (3) DCYF is more likely to serve students of color and students with lower levels of academic achievement; (4) The frequency of participation in DCYF programs increased over time; and (5) A significant proportion of high school graduates and postsecondary students participated in DCYF programs.
