When does the expulsion rate increase?

The expulsion rate typically increases when schools take a more punitive approach to discipline, such as issuing suspensions or expulsions for even minor issues or for behavior that is not dangerous or disruptive to the educational process. When schools take such an approach, it can create a culture of fear in which students may be reluctant to express themselves freely, resulting in further misbehavior or rule-breaking, leading to a further increase in the expulsion rate.
