Disability as Discipline? The Effects of the New York City Suspension Ban on Students with Disabilities. EdWorkingPaper No. 24-902. PDF.

Across the United States, suspension bans have become a popular policy response to address excessive and inequitable use of suspension in schools. However, there is little research that examines what strategies school staff employ when suspension is no longer permitted. I examine the effect of New York City's suspension ban on the use of a potential unintended substitute for suspension: special education classification. Using a dosage difference-in-differences strategy, I find that the ban induced an increase in disability classifications at high risk for classroom exclusion. I show that, on average, students with these classifications in schools with high pre-policy reliance on suspension experienced large declines in test scores, whereas general education students experienced slight test score improvements. Notably, I show that these declines are not due to new, ban-induced classifications actively harming student achievement. These results underscore the importance of considering unintended consequences and vulnerable groups when employing a seemingly "costless" and popular policy lever to reduce schools' reliance on suspension.

Exclusionary Discipline

Suspended from Work and School: Impacts of Layoff Events and Unemployment Insurance on Disciplinary Incidence (with Riley Acton and Austin Smith). IZA Discussion Paper 16423 & EdWorkingPaper No. 23-839. PDF. Under Review.

We study the effects of local labor market shocks and state unemployment insurance (UI) policies on student discipline outcomes in U.S. public schools. By leveraging data on both school-level disciplinary incidence and local, firm-level layoffs across 23 states, we find that ---on average--- exposure to a layoff event has a limited impact on discipline, but this average effect masks important heterogeneity across states with varying levels of maximum UI benefits. At the lowest level of UI benefits ($265), out-of-school suspensions increase by 4.5% from its mean. However, as UI benefits increase, these negative effects are mitigated. Specifically, we estimate that on average, between $480 and $600 in maximum weekly benefits is able to effectively nullify the impact of layoffs on suspensions and expulsions. These effects of layoffs on discipline are driven by large impacts on Black and male students, and we further document that layoff shocks can increase the Black-White gap in out-of-school suspensions when UI benefit levels are low, particularly in predominantly White schools. 

Suspension Restrictions and Restorative Justice Funding in New York City: Interactions between Program and Policy Reform. For Urban Institute's Learning Curve Essay Series.

This study evaluates the 2015 suspension policy reform in New York City that co-occurred with a pilot program for restorative practice funding. In analyzing the joint and independent impacts of these programs on suspension rates, on average and for historically marginalized groups, the data show the suspension restrictions reduced suspension rates, leaving little room for RPs to further reduce suspension rates. Additionally, the restrictions reduced suspensions for low-level offenses and appeared to have spillover effects onto suspensions for more severe behaviors. RP funding did not provide differential spillover effects in this context. The suspension restrictions reduced racial and ethnic disparities in suspension rates, but RPs did not appear to provide any further reductions for Black or Hispanic students. Although there might not be an observable direct reduction in suspension rates attributable solely to RP funding, the provision of and training in a direct alternative to suspension in the wake of restrictions likely reduced any unintended consequences that may ensue when only restrictions are present.

Police in Schools

Overpoliced? Evidence on Targeted Police Interventions in Schools (with Luis Rodriguez). EdWorkingPaper No. 24-1058. PDF.  Under Review.

This study provides a descriptive analysis of police intervention as a response to student behavior in New York City public schools. We find that between the 2016/17 and 2021/22 academic years, arrests and juvenile referrals decreased while non-detainment-based and psychiatric police interventions increased. However, Black students, especially those enrolled in schools located in predominantly White police precincts experiencing a shrinking White student population, experienced disproportionate rates of arrests, juvenile referrals, and police-involved psychiatric interventions. Schools serving more Black students experienced higher rates of interventions relative to schools with fewer Black students, but these higher rates of intervention are not explained by differences in observable student behavior and characteristics. Instead, differences in teacher characteristics and resources contribute to the excess use of police interventions in predominantly Black schools. 

Sexual Orientation and Gender Identity Gaps In STEM

An Institution-Level Analysis of Gender Gaps in STEM over Time (with Joseph Cimpian). In press at Science. Replication files. Link.

Men considerably outnumber women in physics, engineering, and computer science (PECS) majors, with a recent male-to-female ratio of ~4:1, a stark contrast to the near parity in other science, technology, engineering, and mathematics (STEM) disciplines. This gender disparity in PECS carries wide-reaching implications for equity, innovation, and scientific advancement. Analyzing a near-census of >34 million bachelor’s degrees awarded in the US from 2002 to 2022, supplemented with two nationally representative datasets, we provide the first comprehensive study of the gender gap in PECS across higher-education institutions. Institutions serving students with higher math SAT scores have made greater strides in closing PECS gender gaps—both in initial recruitment and retention—whereas those serving students with lower math SAT scores are increasingly struggling. Our findings highlight institutions as strategic leverage points for targeted interventions, particularly to benefit women of color who remain underrepresented even where gender balance is improving.
