Since the 1999 Columbine High School shooting school administrators have been tasked with creating positive education environments while also maximizing the safety of the students and staff. However, limited resources require school administrators to only employ safety policies which are actually effective in reducing crime. In order to help school administrators choose effective policies supported by evidence-based management research, this study sought to determine which of those policies have statistically significant relationships with crime in schools. As such, five social policy factors were determined through an exploratory factor analysis of the US Department of Education's 2007-2008 School Survey of Crime and Safety administered by the National Center for Education Statistics, which interviewed 2,360 principals of primary and secondary schools about the level of crime in their school and the policies used to control it. These five factor loadings included security, policy hindrance, crisis planning, drug controls, and student behavior control concepts. When applied to a linear regression model, security, policy hindrances, and student behavior controls all showed statistically significant relationships to schools with higher levels of crime as did increases in the control variables urbanicity and school size.
