Perhaps there’s another solution, one that doesn’t potentially create a stressful environment for students.
What if some types of schools are safer than others? Is it possible that school choice could improve school safety? Our just-released study suggests it might.
School safety problems
Using survey data from Indiana in 2018, we examined the relationship between school type and the presence of a set of 13 school safety-related practices, including controlled access to the campus and buildings, metal detectors, uniforms, student identification badges, and the presence of security personnel.
We find that private and public charter school leaders tend to be more likely to report “never” having safety problems at their schools than traditional public school leaders. Specifically, our preferred model detects statistically significant private school advantages, relative to traditional public schools, for 8 out of the 13 safety outcomes.
For example, as shown in Figure 1 below, private school leaders in Indiana are about 18 percentage points more likely to report never having student physical conflicts than traditional public school leaders. The results are not statistically significant for the remaining five outcomes.

Figure 2: Public Charter School Safety Problems Relative to Traditional Public Schools
Notes: All estimates reported in figure are statistically significant at the 90% level of confidence. Full results are reported in table 8 of the paper. These estimates are from models that control for school characteristics (level, total enrollment, number of minority students, number of students eligible for the national free and reduced-price lunch program, number of English language learners, number of minority teachers, number of full-time teachers, urbanicity, suspensions, expulsions, and school safety practices) and respondent characteristics (race, gender, position, and income).
The results for public charter schools indicate that eight of the 13 outcomes are not statistically significant, meaning there were no significant differences detected between the propensity for public charter and traditional public school leaders to report never having these school problems. Three statistically significant results suggest that public charter schools may be safer than traditional public schools along these three measures of school problems (likelihood of physical abuse of teachers, racial tensions, and gang activity never occurring), whereas the remaining two results indicate that traditional public school leaders are more likely than public charter school leaders to report that disrespect of teachers and bullying never occur in their schools.
For example, figure 2 shows that public charter school leaders in Indiana are 19 percentage points more likely to report never having student gang activity, but 5 percentage points less likely to report never having student bullying, than traditional public school leaders, all else equal.
School safety practices
We find evidence of private and public charter school safety advantages, even though traditional public schools tend to use more school safety practices (Table 5 in the full report). On five out of seven statistically significant measures, private schools are less likely than traditional public schools to control access to school grounds, perform random metal detector checks, use random dog sniffs for drugs, use security cameras, and have security personnel on campus.
Four out of six statistically significant results indicate that public charter schools are less likely to use various school security practices than traditional public schools. Specifically, public charter schools are less likely than traditional public schools to control access to school grounds, close campus during lunch, use random dog sniffs for drugs, and perform random sweeps for contraband.
Heterogeneous effects
Our study provides evidence of private school safety advantages in Indiana overall. But do private schools that decide to participate in Indiana’s school choice programs differ in their safety advantages? After all, recent studies suggest that lower-quality private schools (in terms of higher enrollment trends, higher tuition levels, and receiving more favorable customer reviews) are more likely to participate in voucher programs in D.C., Florida, Indiana, Louisiana, Ohio, Milwaukee, and Chile.
Our data allow us to examine this question using another quality proxy: school safety.
We find that private schools that elect not to participate in school choice programs in Indiana tend to have larger safety advantages on average than participating private schools. As shown in table 9 in the original study, all six statistically significant heterogeneous effects indicate that safety advantages are larger for non-choice private schools than choice private schools. Specifically, nonchoice private schools tend to have larger safety benefits, relative to traditional public schools, than participating private schools for the following school problems: theft, vandalism, alcohol use, weapon possession, racial tensions, and gang activities.
Our study has its limitations. While we controlled for several student, school, and respondent characteristics, students might differ on unobservable characteristics (such as motivation) across school sectors. Because all of our outcomes are reported by school leaders, they might not accurately reflect the amount or degree of problems within schools. In addition, survey response rates differed across the three sectors, and our results only apply to schools in Indiana.
Given these limitations, results from our study suggest that private and public charter schools may be safer than traditional public schools in Indiana. In light of these results, and the fact that school safety typically places at the top of list of what parents care about when it comes to their children’s schooling, school choice should definitely be a part of the ongoing conversation about school safety.
