There are early warning signs in most cases of violence to self and others, certain behavioral and emotional signs that, when viewed in context, can signal a troubled student. There are different forms of violence in schools.
What is characterized as school violence varies depending on the establishment , who speaks ( teachers , principals, students etc. . ) , Age and sex probably . There is no consensus about its meaning
Violence against the person is one that can be expressed verbally or physically and can take the form of threats , fights , sexual violence , discrimination , bullying , coercion through the use of weapons . Violence against property , in turn , as thefts , burglaries and robberies . The against property is one that is characterized by vandalism and vandalism of school facilities .
School violence is any form of aggression , disrespect and contempt for people , it is the transgression of norms and standards in schools .
It is caused by several factors , especially : family neglect and willful disregard of educating the rules . It is seen as the responsibility of families who failed in the education and the need to impose limits on their children and also the law in their precarious term would generate a sense of impunity in learners .
Educators' perspective the problem of school violence requires much more than mere actions in the educational context . Product being generated , largely because of problems unrelated to a school, school violence require execution of the measures provided for by law , of involvement and responsibility of families and social and governmental actions for solving them , even because the laws exist but have not been real in everyday life of educators and learners .

School violence is difficult to predict in part because many of the cues which in hindsight are indicative of a potential school shooter are prevalent among non-shooters as well. This is in part why the U.S. Secret Service National Threat Assessment Center on the Prevention of School Violence (Vossekuil et al., 2000) reported that while there are common traits among those who engage in school violence, a profile could not be used to identify such threats. Those traits include:
(1) White and male
(2) Engaging with violent forms of media (e.g., music, film, television, video games)
(3) A fascination or interest in weapons
(4) An interest in death or death related topics
(5) Depression or chronic negative affect
One additional findings common on a very high percentage of school shooters is that they often experience chronic social exclusion or ostracism and the violence preciptates after an acute, often severe experience of exclusion.
For students who may engage in violence towards themselves, I agree with what was posted by many others; general avoidance and disengagement (particularly when this is a change from previous behaviors), changes in performance, and obvious social ostracism will all be indicators of a student who may be consider harm.
