There has been much debate whether the trend in school violence has increased or decreased during the last quarter of the 20th century and into the 21st century.Nationally, there has been a view that school violence was on the increase, especially in the areas of assault, sexual harassment, and the use or possession of weapons.While the perception indicated an increase, the research revealed otherwise. School violence, overall, has decreased, while the number of multiple homicides has increased(Wright and Clymer 2000).
