Examines the effectiveness of a peer mediation program in which 6th-8th grade students (N=30) were trained to serve as mediators for peers in conflict. Mediators' responses to written tests indicated increased knowledge of mediation skills after training. Results reveal that 32 of 34 mediations resulted in satisfactory conflict resolution and that school-wide suspensions decreased during the intervention year. (Contains 24 references and 3 tables.)
