School Violence Overview
By virtually every measure, students in U.S. junior and senior high schools are at a lower risk of in-school victimization than they were ten years ago. Yet their perceptions say otherwise.
The statistics  show thefts and acts of violence declining in almost every category:
The picture was not altogether rosy:
While the level of overt violence was declining, student perception of school safety was deteriorating. In the two most recent national surveys,  students reported feeling more at risk at school than away from school, and the percentage of students who reported that they had skipped school at least once in the previous month because they were concerned for their safety increased 19 percent between 1993 and 2003.
