Subclaims¶

q2 i? Students in schools that fully removed SROs had a probability of a high-level infraction 2.2 percentage points lower than expected in 2022-23, a statistically significant difference-in-difference estimate. → Arneson 2024 q2 i? Schools that fully removed SROs saw a typical increase of only 13 high-level infractions over the period, 42 fewer than expected, a statistically significant difference. → Arneson 2024 (2)

Evidence¶

Arneson 2024¶

Arneson, A., Hinze-Pifer, R., Franklin, K., & Johnson, D.W. (2024). Removing police officers from Chicago schools: Trends and outcomes. Chicago, IL: University of Chicago Consortium on School Research. https://consortium.uchicago.edu/publications/removing-police-officers-from-Chicago-schools

q2 · i? · causal · r2

Difference-in-difference analysis of CPS administrative data comparing 2018-19 to 2022-23, controlling for observed student and school characteristics. The student-level estimate was "lower than that expectation by 2.2 percentage points" and statistically significant; the 1.3 percentage point estimate for partial removal was not.

"the actual rate in 2022–23 for students in schools that fully removed SROs is lower than that expectation by 2.2 percentage points. This is the difference-in-difference estimate, and it is statistically significant."

q2 · i? · causal · r1

School-level Poisson count analysis of the 72 high schools with two SROs at baseline. Schools retaining both SROs rose from 118 to 173 high-level infractions; full-removal schools rose "from 116 in 2018–19 to 129 in 2022–23", a significant difference-in-difference. Partial removal showed about 14 fewer than predicted, not significant.

"the typical increase over time was just 13 (from 116 in 2018–19 to 129 in 2022–23) which is 42 high-level infractions lower than the expectation if there was no effect of SRO removal and is statistically significant."

Discussion¶

Related Claims¶

• High schools that retained SROs had higher suspension rates, were smaller, and served more socioeconomically disadvantaged students — related
• SRO removal was not significantly related to changes in overall discipline infractions or in suspensions at either the student or school level — related
• Police notifications declined substantially in schools that fully removed SROs, but the difference-in-difference was not statistically significant — related
• SRO removal was not significantly related to changes in student or teacher perceptions of physical safety or in Student-Teacher Trust — related
• Schools with school resource officers may have higher rates of exclusionary discipline, including a reported 21 percent increase in incidents — related
• Common non-curricular policing strategies show no overall effects on measures of school crime or discipline — reports the opposite
