Final answer:
To have a successful peer mediation program, time during the school day, time after school, and a developmentally appropriate curriculum are necessary, but adult trainers for peer counselors are not.
Step-by-step explanation:
To determine which of the options is not necessary for a successful peer mediation program, we need to consider each choice. Option a) is important as it provides dedicated time during the school day for mediation sessions, allowing students to address conflicts promptly. Option b) is also beneficial as it offers additional time after school to accommodate students' schedules. Option c) is crucial as it ensures the curriculum is age-appropriate and suitable for students' development. However, option d) is not necessary for the success of a peer mediation program. While adult trainers can provide guidance and support, the primary goal of a peer mediation program is to empower students to mediate conflicts among themselves.
