“…Moreover, in order to best explore the various mechanism within this process, we focus on three different dimensions of achievement—attitudes, ability, and course-taking. While there are likely multiple aspects of disciplinary involvement and academic exclusion that, together, can push students out of schools, we follow Jabbari and Johnson (2020) and focus on suspensions and math achievement, whose trajectories can represent important pieces of larger opportunity structures in society, such as the School-to-Prison (STP) pipeline and the science, technology, engineering, and math (STEM) pipeline. Additionally, as many of the same groups of students that are underrepresented in math achievement and the STEM workforce are also overrepresented in suspensions (Skiba et al, 2002) and the criminal justice system (Pettit & Western, 2004), our analysis also focuses on race/ethnicity.…”
