The EVOSST project is a groundbreaking initiative focused on enhancing the efficiency and understanding of social services across the European Union, aligning with the European Pillar of Social Rights. It aims to develop advanced models for life-course impact assessment, providing valuable insights into long-term outcomes in healthcare, childcare, education, and inclusion. By integrating well-being metrics and adopting a “beyond GDP” perspective, the project emphasizes sustainable development, societal well-being, and social cohesion.
