The evidence that student learning declines sharply (or stagnates) during the summer has motivated a substantial interest in programs that provide intensive academic instruction during the summer. However, the existing literature suggests that such programs, which typically focus on just one or two subjects, have modest effects on students’ achievement and no impact on measures of their engagement in school. In this quasi-experimental study, we present evidence on the educational impact of a unique and mature summer learning program that serves low-income middle school students and features unusual academic breadth and a social emotional curriculum with year-to-year scaffolding. Our results indicate that this program led to substantial reductions in unexcused absences, chronic absenteeism and suspensions and a modest gain in ELA test scores. We find evidence that the gains in behavioral engagement grow over time and with additional summers of participation. Our results also suggest that these effects were particularly concentrated among boys and Latinx students.

A growing body of evidence suggests that vocationally focused programs of study substantially improve high-school completion and longer-run economic success. However, the corresponding recommendations to expand vocational programs may have unintended, negative consequences for low-income, academically successful students (i.e., the “missing one offs”) who have the capacity and motivation to attend highly selective universities. This study contributes to our understanding of these issues by examining an innovative, college-preparatory program targeted to academically successful Chilean students attending vocational high schools serving lower-income communities. This program (Escuela Desarrollo de Talentos or EDT) provides academic and social-emotional supports aligned with admission to selective universities. We examine the educational effects of EDT participation using a fuzzy regression-discontinuity design based on its eligibility rules. We find that the EDT program did not increase the probability of graduating from high school but did increase performance in math courses. We also find corresponding evidence suggesting that EDT participation increased math performance on college entrance exams and shifted students away from further postsecondary vocational training and towards matriculation at elite universities.

The My Brother’s Keeper (MBK) Challenge developed by President Obama supports communities that promote civic initiatives designed to improve the educational and economic opportunities specifically for young men of color. In Oakland, California, the MBK educational initiative features the African American Male Achievement (AAMA) program. The AAMA focuses on regularly scheduled classes exclusively for Black, male students and taught by Black, male teachers who focus on social-emotional training, African-American history, culturally relevant pedagogy, and academic supports. In this study, we present quasi-experimental evidence on the dropout effects of the AAMA by leveraging its staggered scale-up across high schools in the Oakland Unified School District (OUSD). We find that AAMA availability led to a significant reduction in the number of Black males who dropped out as well as smaller reductions among Black females, particularly in 9th grade.
