Suicide is a leading cause of death among youth ages 10 years and older. Further, recent federal surveillance data suggest the rates of suicidal ideation and behaviors to be increasing. With these facts in mind, in this paper, we examine the school psychologist's role in suicide risk assessment; which assesses the degree to which students, who have conscious thoughts of suicide, are at risk for engaging in a suicidal behavior. After acknowledging the limitations of school-employed mental health professionals when it comes to these activities, we begin by reviewing suicide risk factors and warning signs. Next, we discuss an approach to the identification of suicidal thinking. Finally, we provide guidance on a school-based suicide risk assessment protocol, which guides actions necessary to stop suicidal behavior and place students in a position from which suicidal ideation can be addressed.
