Earning a high school diploma is a milestone that has been linked to many later life outcomes, from employment to incarceration to physical health, and impacts society as a whole through tax revenues and government spending. Yet, youth leaving school prior to obtaining a diploma remains a challenge nationwide, particularly in large cities. Given the importance of a high school credential, many interventions have been tested to curb school-leaving and support students through graduation. Congreso's Éxito program, the focus of this report, is focused on providing that support and consists of an afterschool program combined with case management services provided to a subset of students. This report focuses on the impact the Éxito program had on participating students at Kensington Creative and Performing Arts (KCAPA) who started high school in 2016-17 and examines their outcomes through 2019-20, what should have been their senior year. This report concludes with recommendations for Congreso and for the wider out-of-school time field. [This report was co-produced by Congreso de Latinos Unidos.]
