With more than six thousand charter schools in the United States, charter school outcomes are a growing field of study within the broad discipline of education and specifically within school social work. However, there is little research to document the demographic and clinical characteristics of social workers in charter schools. The current study will examine demographic and practice characteristics of school social workers (n = 298) in one state and compare three school types: traditional public schools, charter schools, and takeover schools. Results from the cross-tabulation analysis demonstrate that both demographics and practice tasks vary according to school type. Implications for practice and research will be discussed.
