Traumatized youth are at an increased risk of a host of negative academic and psychoeducational outcomes. Screening and identification of students who experience potentially traumatic events may help schools provide support to at-risk students. In light of this, the current study examines the availability and use of trauma screening measures to detect early indicators of risk among youth in schools. A systematic review was conducted to identify measures available to screen children and youth for trauma exposure and/or symptoms, as well as the associated psychometric properties to support each instrument’s applied use in schools. Eighteen measures met inclusion criteria, which consisted primarily of student self-report rating scales and clinical interviews. While many instruments measure the symptomology or exposure to trauma among children and youth, very little psychometric evidence was available to support the use of these measures in schools. Additional research is needed to endorse and expand the use of trauma screening measures in schools.
