School social workers and school security personnel are increasingly being integrated into U.S. schools; however, there is little available literature concerning the interactions between school social workers and school security personnel. This article will report descriptive findings of a study that investigated school social workers' interactions with and perceptions of school security personnel in one Southeastern state. Data were collected from sixty-seven practicing school social workers. Quantitative and qualitative results will be discussed within the context of school social work practice. The purpose of this article is to provide timely implications for school social work and to offer recommendations for social work practice, education, and research in light of increased use of school security personnel in U.S. schools.
