This qualitative study examined perceptions of the causes and nature of conflicts and violence among African-American girls in an urban high school. In-depth, iterative interviewing was used to explore the perceptions of these girls, male students, teachers, and other school personnel. Ethnographic observation was also used. Conflicts and violence among girls were produced by an insult or accusation made by one girl against another which by group norms required a commensurately aggressive response. Peers actively pressured girls to fight and those that did not were scapegoated by others. However, a mediation service was used by girls to end conflicts successfully.
