This study examines the ways that participation in youth organizing groups while in high school impacts the educational and civic trajectories of young adults. The study, conducted by UCLA Professor John Rogers and USC Professor Veronica Terriquez, compares the experiences of former members of youth organizing groups to those of a randomly selected sample of young adults who never participated in youth organizing while in high school. Rogers and Terriquez find that youth organizing alumni are far more likely than comparable peers across California to enroll in four-year colleges and universities and engage in various civic activities in early adulthood. These findings provide further evidence for the value of youth organizing: In addition to building power and garnering significant policy "wins," youth organizing groups are powerful agents for youth development. The report organized into sections. Section one presents a rationale for examining the impact of youth organizing on the development of young adults, describing both the rapid growth of youth organizing groups in recent years as well as efforts to study this emerging field. Section two discusses the methods used to investigate the impact of youth organizing. Section three describes the youth organizing alumni sample and the groups that these young adults participate in while in high school. The central findings of the study are presented in sections four (on educational attainment) and five (on civic identity and engagement). The concluding section points to implications of key findings and identifies questions for future work.
