Suicide is the second (behind accidents) leading cause of death for 15- to 24-year-olds. Schools are in a unique position to make a difference in suicide prevention by addressing three distinct phases of the problem: prevention, intervention, and post factum. Factors are identified that have a direct bearing on level of risk and should be carefully incorporated into a suicide prevention planning effort. The goal of intervention is to identify at-risk youth early and to coordinate school resources to continue an active role of intervention until stability has been achieved. Each school will need to adopt plans and procedures to cope with the crisis of a student suicide. Excerpts from the suggested procedures for schools in Fairfax County, Virginia, highlight steps to take when a suicide or similar crisis occurs. Summaries of the suicide prevention programs in Fairfax County and in the Quakertown Community School District, Pennsylvania, illustrate what schools can do to prevent suicide.
