Cedefop’s RESET (REgional Skills EcosysTems index) is a new composite index designed to measure and compare skills ecosystems across EU (NUTS2 level) regions. By aggregating diverse indicators from four skills pillars into a single, robust score, RESET provides a holistic picture of how skills are developed, deployed, and supported. Skills underpin not only individual employability but also serve as critical enablers of broader economic and societal objectives, including productivity and social cohesion. RESET captures the complexity of skills ecosystems, highlighting their role as the foundation of innovation capacity, economic resilience and EU competitiveness.
