Study: Black Students—Not Crime—Determine If Schools Get Security

“To the extent that police in schools may contribute to the disproportionate arrest of African-American students, the use and/or role of police in schools should require careful reexamination,” an overview of the study provided to TPM said.

The study was conducted by Tim Servoss, a professor of pyschology at Canisius College in New York, and Jeremy Finn, a professor of education at the State University of New York at Buffalo. The results of the study are scheduled to be presented in full at April’s American Educational Research Association conference in Washington, DC.

Servoss and Finn relied on a sample of about 700 high schools, drawing from the data of three national surveys. Three-quarters of those schools employed at least one part-time police officer. Fifty-seven percent of the schools with an officer present had no student arrests, a point Servoss highlighted to show that the "results don't support the notion that all police in schools are bad."

He and Finn found that crime and misconduct within a school played a role in predicting if a school would take security measures, including drug testing, metal detectors, drug surveillance dogs, and the presence of security guards or police.

“However, the proportion of African-American students was a significant predictor of security even when controlling for the same background characteristics and crime and misconduct within the school,” the researchers said in their overview. “These results suggest that the implementation of security measures are at least partially based on the perceived threat of the African-American student population rather than any objective dangers within (crime or misconduct), or in the neighborhood (neighborhood crime) surrounding the school.”

These security measures, in turn, increased the likelihood that a black student would be suspended when compared to a white student, particularly when a school uses drug surveillance measures, (i.e., drug testing, dog sniffs, random contraband searches). In a school without these measures, black students were twice as likely to be suspended than their white peers. With these measures, black students were three times as likely. This disparity exists after controlling for school size, racial composition, socioeconomic status, urbanicity, and school indiscipline.

Finally the study looked at arrests rates, with the researchers noting in their overview, “Unlike other school personnel, police have the authority to arrest students.”

There, it found racial disparities were also greater.

“In the average school without police, the black-white disparity in arrests was negligible," the authors wrote, with black students being 1.3 times more likely than white students. But with police present, African-American students were 2.2 times more likely to be arrested than white students, they concluded.

A separate but related study conducted by Finn and Servoss using the same data set found, “When one or more police officers are in a school, the odds are three times as likely that the school will have a high number of arrests (among similar size schools), even when indiscipline and the composition of the student body are controlled statistically,” according to an overview sent to TPM.
