This document summarizes the key learnings from a project between schools in Greece and Norway focused on approaches to delinquent behavior. The Greek school of Archangelos had best practices in areas like clear attendance rules, teachers having close relationships with students, and involving the local police. The Norwegian school of Fyllingsdalen found that some of these practices could potentially be transferred, like increasing teacher-student engagement, but that other practices were difficult to replicate due to differences in laws and resources. The document concludes by thanking the Greek partners for their collaboration.
