The EDDI project aims to help teachers, families and students to better understand the causality and consequences of leaving education in order to find possible solutions to the ESL (early school leaving) problem. We believe that only a comparative analysis of practices and interventions between countries which do well in the ESL statistics and those at the opposite end of the spectrum would deliver a sustainable solution to the ESL problem. Besides economic and social mobility impacts, ESL has been linked to bullying, violence or micro criminality. ESL is a threat to the successful future development of the workforce and community prospects.
