Researchers have shown that receiving suspensions is associated with negative educational outcomes. However, existing studies fail to control for unobservable differences between those students who received suspensions and those who did not. In this study, I compare achievement for a given student across school quarters with varying types and levels of suspensions by taking advantage of a unique dataset that measures student achievement at 12 time points across 3 academic years. Results show that multiple suspensions are associated with lower math and English language arts achievement even after controlling for differences between students. Furthermore, I find suggestive evidence that these associations are stronger for students who have an elevated risk of suspensions.

Existing research on theories of intelligence shows that students with growth mindsets tend to outperform those with fixed mindsets in mathematics. We used nationally representative data to address two related questions in the general population: (a) Are there subgroup differences in the endorsement of a fixed mindset? (b) Does the negative association of a fixed mindset and math achievement vary across subgroups? We found that White students and students from higher socioeconomic backgrounds are more likely to view intelligence as a fixed trait than non-Whites and students from lower socioeconomic backgrounds. Furthermore, for low-achieving students, we found that a fixed mindset at 10th grade predicted lower gains in academic achievement by 12th grade than it did for their high-achieving counterparts. Our results reflect that contextual differences play a critical role in shaping fixed mindsets and its consequences.

Schools use an array of strategies to match curricula and instruction to students' heterogeneous skills. Although generations of scholars have debated ''tracking'' and its consequences, the literature fails to account for diversity of school-level sorting practices. In this article, we draw on the work of Sørensen and others to articulate and develop empirical measures of five distinct dimensions of within-school cross-classroom tracking systems: (1) the degree of curricular differentiation, (2) the extent to which sorting practices generate skills-homogeneous classrooms, (3) the rate at which students enroll in advanced courses, (4) the extent to which students move between tracks over time, and (5) the relationship between track assignments across subject areas. Analyses of longitudinal administrative data following approximately 20,000 eighth graders enrolled in 23 middle schools through the 10th grade indicate that these dimensions of tracking are empirically separable and have divergent relationships with student achievement and the production of inequality.

Between 2003 and 2013, the proportion of California 8th graders enrolled in Algebra or a more advanced course nearly doubled to 65 percent. In this paper, we consider the organizational processes that accompanied this curricular intensification. Facing a complex set of accountability, institutional, technical/functional, and internal political pressures, California schools responded to the Algebra-for-all effort in diverse ways. While some schools detracked by enrolling all 8 th graders in Algebra, others "tracked up," creating more advanced geometry opportunities while increasing algebra enrollments. These responses created a new differentiated course structure that is likely to benefit advantaged students. Consistent with the Effectively Maintained Inequality hypothesis, we find that detracking occurred primarily in disadvantaged schools while "tracking up" occurred primarily in advantaged schools.
