Conflict, generally defined as a fight, struggle, battle, disagreement, dispute, or quarrel (Johnson & Johnson, 2009, p. 368), exists wherever human interaction occurs and is a seemingly inevitable component of any social group. It is driven by such issues as incompatibilities between the parties, perceived differences in needs, beliefs, and values, and limited resources (Johnson & Johnson 1995, 1996, 2009). Schools as institutions and as communities are therefore not without conflict when students, staff, and parents interact in and around the school. Nor are schools without aggression. Intricately interwoven with conflict, aggression becomes evident early in life, involves a deliberate intent to harm, often uses force or domination over others, and evolves from physical through verbal to indirect forms as children develop their social skills, language capabilities, and social intelligence (Tremblay, Gervais, & Petitclerc, 2008).
