The education system is facing great challenges in recent times. Transformations can be observed in the dynamics of the teaching-learning processes, moving from methodologies based on the transmission of contents to other ways of proceeding oriented towards the association of knowledge, competences and values, where the involvement of students as the protagonist of their own learning is pursued. This is why issues such as the prevention of risk behaviour and the improvement of personal competences for the improvement of the psychosocial well-being of students (and also of teachers), are presented as priority objectives in the planning of educational actions. From this integrative perspective of development, it is necessary to have solid scientific evidence to support new initiatives in education. This symposium contains different papers, both empirical analysis and systematic review, as well as the proposal of different innovative initiatives that have been implemented with secondary school students. They give visibility to the different variables that make up the personal competences worked on in the educational field to favour the development of students and teachers in Secondary Education. Finally, a project is presented for the promotion of the integral wellbeing of adolescents, from a positive approach, with the development of innovative tools for the prevention of problematic behaviour, such as violence and consumption.
