Public schools have made an attempt to combat the problem of middle school violence by employing police officers, called school resource officers (SROs), to serve on campus. However, there is a gap in the academic literature addressing the relationship between SRO leadership styles and middle school violence. The purpose of this study was to explore the nature of the relationship between SRO leadership styles and middle school violence and whether differences in how administrators perceived SRO leadership had any bearing on the prevalence of student expulsions. Trait theory and process theory provided the theoretical foundation for this study. Thirty SROs and 90 administrators from 30 middle schools in a southern state participated in this study. Data were acquired through the Campbell Leadership Index (CLI) survey. SROs self-reported data on the CLI, and administrators reported CLI data based on their observations and perceptions of SRO leadership. Index scores were correlated using the Pearson correlation coefficient. Key findings concluded that middle schools with higher expulsion rates also tended to have SROs with higher administrator-observer ratings than SRO self-ratings, indicating that there does seem to be a relationship between expulsion and leadership perception. Interestingly, there was not a statistically significant relationship between SRO self-reported leadership style and expulsion rates. The implications for positive social change are that the results of this study can be used to better understand and improve the working relationship between SROs and school administration and understand how leadership impacts expulsion among middle school students, thereby potentially improving the number of students who remain in school and graduate.
