The purpose of this study is to determine the prevalence of research on the implementation of trauma-informed practices published in leading journals within the field of school psychology and within the auxiliary school-based mental health fields of social work and school counseling. The intention is to identify whether a call to action is warranted for school psychology researchers and practitioners to enhance their awareness and preparedness to address the increasing presence of trauma and its impact upon student development. Additionally, the inclusion of related research in the fields of social work and school counseling is motivated by an acknowledgment that the efforts required to systematically address the impact of trauma on student development necessitate a collaborative team strategy with school-based mental health professionals, school personnel, and administrators. Furthermore, as researchers have identified the disproportionate impact of trauma on urban schools (i.e., those whose populations are characterized by high poverty and a majority presence of minoritized identities), a supplementary aim of this systematic review is to investigate the prioritization of these demographics within published works.
