The purpose of this study was to examine school counselors' perceived role and self-efficacy in managing multiparty student conflict. Literature on conflict resolution in the field of education has not addressed conflicts that take place among three or more students, or multiparty student conflict. Therefore, investigated in this study were middle school counselor's perceptions of the frequency of multiparty student conflict, types of delivery used, theoretical approach, and self-efficacy in managing multiparty student conflicts. Participants included 357 members from the American School Counselor Association who were practicing middle school counselors. It was found that school counselors encounter multiparty student conflicts and have a high level of self-efficacy in managing these conflicts. ANOVA testing determined that counseling small groups, teaching conflict resolution skills to small groups, and teaching skills to large groups were types of delivery related to self-efficacy in managing multiparty conflicts. A Spearman correlation was calculated to find a significant relationship between self-efficacy in managing multiparty student conflict and the use of theoretical approaches.
