While the effectiveness of metal detectors to improve school safety remains debated, many public schools continue to rely on this technology to control school violence. Among them is the 1% of public schools where students are searched on a daily basis by metal detector. This study examines the school-level risk factors associated with daily searches to estimate the disproportionality of their use in high-violence, majority-minority public schools. Analyzing data from the 2007−2008 School Survey on Crime and Safety, this study finds that 91% of public schools that perform daily metal detector searches of students are high-violence, majority-minority schools. However, the results also show that, among high-violence schools, those with majority-minority enrollments are significantly more likely than others to conduct these searches. The article concludes with a discussion of the implications of policy responses to school violence that are distinct and disproportionate according to student demographics, rather than safety conditions.

The National Center for Education Statistics reports that, in the 2009−2010 school year, only 1% of public schools conducted daily metal detector checks of students. Urban schools (3.7%), high schools (4.8%), schools of 1,000 students or more (4%), schools enrolling 50% or more students of color (3.4%), and schools where more than three quarters of
