How should schools assign students to more rigorous math courses so as best to help their academic outcomes? We identify several hundred California middle schools that used 7th grade test scores to place students into 8th grade Algebra courses, and use a regression discontinuity design to estimate average impacts and heterogeneity across schools. Enrolling in 8th grade algebra boosts students’ enrollment in advanced math in 9th grade by 30 percentage points and 11th grade by 16 percentage points. Math scores in 10th grade rise by 0.05 standard deviations. Women, students of color, and English-language learners benefit disproportionately from placement into early Algebra. Importantly, the benefits of 8th grade algebra are substantially larger in schools that set their eligibility threshold higher in the baseline achievement distribution. This suggests a potential tradeoff between increased access and rates of subsequent math success.
The well-documented racial disparities in school discipline have led many school districts in the U.S. to adopt restorative justice practices. The restorative justice philosophy differs from traditional disciplinary action by placing an emphasis on restitution and improving behavior rather than punishment. While models of restorative justice are descriptively and theoretically promising, research on restorative practices in schools is limited. We use student-level administrative data and a difference-in-difference design to measure the changes in student discipline outcomes that occurred under restorative justice in Pacific City schools between the 2008-2017 school years. Results indicate that restorative justice practices led to an overall reduction in disciplinary action. However, results also show that restorative justice practices had differential effects between racial groups, with White students benefiting most from restorative justice. These findings suggest that while the overall effects of restorative justice are promising, these practices may unintentionally widen the racial disproportionality in school discipline they are instituted to mitigate.
