Temporal Variations in School-Associated Student Homicide and Suicide Events – United States, 1992-1999

To evaluate whether the risk for school-associated violent death varies during the school year, CDC analyzed monthly counts of school-associated homicide & suicide events that occurred among elementary & secondary school students in the USA. This report summarizes the results of these analyses, which indicate that student homicide event rates are usually highest near the start of the fall & spring semesters, & suicide event rates are highest during the spring semester. These findings can assist school personnel in planning & implementing violence-prevention programs.
