The document summarizes key points from a European seminar on policies to prevent early school leaving. It provides an overview of the Drop In project, which aims to map actors, policies, monitoring systems, and exchange best practices. Models from Iceland, Finland, and remediation approaches are discussed. Some early conclusions stress the importance of early intervention, alternative pathways, counseling, and designing local prevention and remediation practices based on scientific models, with monitoring of student well-being, transitions, and feedback to schools.
