Resumen: The 2PASS-4Health project (Promoting Physical Activity in Secondary School for Health) was founded by the Erasmus+ Sport programme of the European Union to improve the participation in sport and physical activity (PA). This project aims at examining examples of PA promotion interventions in secondary school, identifying good practices as well as the main barriers and difficulties linked to the design, implementation and evaluation of such interventions in order to improve their quality and sustainability. This project targets both the scientific community and various stakeholders involved in school-based PA promotion for adolescents to provide them with clear knowledge and usable tools. The overall design of this project will be presented as well as the first results and deliverables created to implement the interventions.
