description: Momentum toward removing school-based law enforcement (SBLE) has increased since the summer of 2020. This change has occurred due to issues of equity with the hope that removing SBLE will reduce existing racial and ethnic disparities in the criminal justice system. SBLE refers to sworn law enforcement stationed in schools on either a part- or full-time basis. Some SBLE are known as school resource officers, who often receive special training in juvenile law and interacting with students in schools, although this varies from state to state. Other SBLE do not receive any special training in working with young people.
Although the move toward removing SBLE may have intuitive appeal to some school districts, no empirical evidence exists regarding what happens to students' frequency of contact with the criminal justice system after schools remove SBLE. Similarly, current research has not examined the impacts on the attendant racial and ethnic disparities.
All the data used in this study are secondary data from the National Center for Education Statistics (NCES), including both the publicly available Civil Rights Data Collection (CRDC) and the restricted-use School Survey on Crime and Safety (SSOCS). All data cleaning, manipulation, and analysis will be done using syntax files in Stata. This study is a collection of these three Stata .do syntax files.
This study compared changes in three measures of criminal justice contact (i.e., arrests, referrals to law enforcement, and crimes reported to police) in schools that removed SBLE relative to the changes in schools that did not remove SBLE. The study examined within-school racial and ethnic differences in rates of arrest and referrals to law enforcement, and between-school differences in all three measures of criminal justice system contact by school racial composition.
description: The purpose of this study was to examine the impact of removing school-based law enforcement (SBLE) on racial and ethnic disparities in criminal justice system contact. This study sought to address the following research questions.

How does removing SBLE relate to changes in school-based arrest rates, referrals to law enforcement, and reporting crimes to police?
How do these relationships differ by school racial and ethnic composition?
How do these relationships differ by student race and ethnicity?
description: Each of the two data sources (Civil Rights Data Collection (CRDC) and School Survey on Crime and Safety (SSOCS)) were used to construct a two-wave longitudinal dataset that would identify schools that removed or did not remove school-based law enforcement (SBLE). It was not feasible and potentially unethical to do a true experimental design, the current study used a quasi-experimental difference-in-differences design. A difference-in-differences design compares the difference between pre- and post-intervention measures (difference one) between treatment and comparison units (difference two). In this study, the treatment units were schools that removed SBLE. The comparison units were schools that had SBLE at both waves.
One of the methodological shortcomings of difference-in-differences designs, including the study proposed here, is the threat of selection bias--that schools that removed SBLE are fundamentally different from the comparison schools. To address this issue, this study balanced treatment and comparison groups using entropy balancing, ensuring that the treatment and counterfactual groups are as similar as possible on a set of baseline characteristics. This approach was used with both source studies mentioned above.
