The PeaceBuilders program, developed by PeacePartners (California, USA) in 2003, aims to prevent violence in schools through the creation of safe, positive learning environments, and the promotion of prosocial behavior among students and adults. Core practices within the Peacebuilders program include: engaging parents and other adults in the community in teaching and promoting key values and behaviors, praising good behavior on a daily basis, and fostering the skills needed to resolve conflicts peacefully, without aggression or insults.

Peacebuilders is designed for use in elementary and middle schools (K-8) and has been implemented in more than 1200 schools and organizations in the US. Implementation tools (e.g., curriculum, materials for students), workshops and coaching for educators are available through the website.
