Holding a summer job is a rite of passage in American adolescence, a first rung towards adulthood and self-sufficiency. However, over the past decade, youth employment during the summer has decreased significantly. Summer youth employment has the potential to benefit high school students' educational outcomes and employment trajectories, especially for low-income youth. Despite the potential importance of youth employment during summer, evidence of the impact of summer jobs on youth outcomes is limited to only a few studies. Our research examines summer youth employment, beginning with academic outcomes, by studying New York City's Summer Youth Employment Program (SYEP). SYEP provides jobs to youth ages 14-24, and due to high demand for summer jobs, allocates slots through a random lottery system, allowing for causal estimates of program impact. Our study uses student-level data from the New York City Department of Youth and Community Development (the SYEP administrating agency) and New York City Department of Education, encompassing approximately 300,000 student SYEP applicants for the 2005-2009 program years. This paper examines the impact of SYEP on a wider range of academic performance outcomes, including test taking, passing rates and scores. It also attends to variation in these outcomes. Our findings suggest that SYEP has positive impacts on some student academic outcomes, and that these effects are heterogeneous. Future analyses will focus on examining program, student and school characteristics that might explain these variations. The following tables are appended: (1) Lottery randomization results; (2) Attrition in year following application to SYEP, Grade 8-11 and alternative program, 2005-08; and (3) Impact of selection on attrition, by grade.
