Suicide is a major public health issue that affects people of all ages, backgrounds, and racial and ethnic groups throughout the country. When a student commits suicide, it is not only a tragedy for his or her family, but it can also significantly affect other students and disrupt school learning environments. While the causes of youth suicide are complex and determined by multiple factors, the goals of suicide prevention are simple: reduce factors that increase the risk of suicide and increase factors that promote resilience and encourage an effective community response to the risk. Schools play an important role in reaching these goals. The U.S. Department of Education's Office of Safe and Healthy Students (OSHS) provides resources to promote safe and supportive learning environments for all students. This fact sheet gives an overview of youth suicide and links to useful resources for educators on suicide prevention. The following topics are presented: (1) Warning signs for suicide; (2) How prevalent is suicide among America's youths and students?; (3) What are the risk factors for suicide?; (4) What can schools do to prevent youth suicide?; and (5) Where can I find resources on suicide prevention?
