The School Violence Index (SVI) is a ratio of violent incidents to enrollment in a school and is determined by the number of incidents, the seriousness of the incidents, and the school’s enrollment. The table below provides the weights for each type of violent incident that carries a weight.

To calculate the SVI for each school, the incident counts for each type of incident are multiplied by the weight for that type of incident and those products are added together to obtain an overall weighted incident total. This total is then divided by the enrollment, which results in the SVI score.
