Taking a decidedly practical approach to health education, this book describes and illustrates the various stages of the project process, taking into account the specific characteristics of the school environment. Designed as a methodological guide, it is intended to assist educational teams and practitioners in the development, implementation, monitoring, and evaluation of their health education initiatives. Produced in collaboration with stakeholders from the French Ministry of Education, it aims to provide meaningful support for the implementation and development of health education in schools.
